Subsea NHI: A Field Brief

NOTE: This document is a work of fiction and should not be interpreted as a reflection of official policy, doctrine, or capabilities. Any resemblance to actual events, organizations, procedures, or individuals, whether living or deceased, is purely coincidental and unintentional.

The following field brief provides an overview of subsea non-human intelligence (NHI), related subsea and transmedium craft - variously termed unidentified anomalous phenomena (UAP) or unidentified submerged objects (USOs) - and NHI bases of operation, as well as guidance for communication, interaction, and OPSEC. ‡

INTRODUCTION:

As human operations in the subsea domain expand in both scope and complexity, increased contact with subsea NHI is inevitable. This field brief provides a conceptual framework for assessing and responding to subsea NHI activity. It enables operators, analysts, and commanders to approach encounters with clarity, consistency, and tactical discipline, and equips them with the foundational knowledge needed to interpret contact, inform response planning, and support cross-domain awareness.

The principal audience includes the Surface Warfare (SUW), Undersea Warfare (USW) and Subsea and Seabed warfare (SSW) communities. Commanders and analysts within Navy, Coast Guard, or joint task force elements tasked with anomalous activity assessment or undersea domain awareness are advised to reference this brief as a baseline for planning, identification, and containment protocols. Researchers, wargamers, and defense educators working in advanced threat modeling, future warfare, or cross-domain phenomena may also employ this publication to support scenario development and strategic foresight.

To preserve operational security and ensure consistent reference across reporting channels, the following designations have been adopted for use in all official documentation and communications pertaining to anomalous subsea phenomena. The term “RESIDENT” refers to any biologically or artificially intelligent non-human entity operating within the maritime domain. “FAST MOVER” is the assigned designation for unidentified craft, vehicles, or transmedium platforms exhibiting advanced mobility, control, or propulsion characteristics. “CLUSTER” denotes a fixed or mobile subsea structure, installation, or habitat associated with Resident activity. These designations are intended to standardize internal reporting and reduce exposure risk through controlled terminology.

RESIDENTS

▶︎ ORIGINS
The nature of Residents remains unknown, and no confirmed evidence exists regarding their origins. However, three prevailing hypotheses offer distinct ontological frameworks, each with unique implications for detection, engagement, and strategic interpretation.

1. Extraterrestrial - Residents travelled to Earth from either within or outside our solar system, and established a Cluster or Clusters in hidden or inaccessible environments of the deep ocean.
2. Indigenous - Residents are a non-human, intelligent species coexisting with humanity on Earth in hidden or inaccessible environments of the deep ocean. (Sometimes referred to as the Cryptoterrestrial hypothesis.)
3. Interdimensional - Residents originate from or exist in a dimension beyond the three spatial dimensions and one time dimension we experience, and are capable of moving between dimensions by manipulating time and space. These dimensions could be higher spatial dimensions (4D and beyond), parallel realities or universes, or alternate timelines.

▶︎ INTERPRETIVE FRAMEWORKS
In the absence of confirmed origin, biology, or intent, three primary frameworks have emerged to contextualize Resident presence and behavior. These models are not mutually exclusive and may represent different facets of a single phenomenon. Each carries distinct implications for detection, engagement, and strategic posture.

• Biological Evolution – Adapted to high pressure, low light, and isolation.
• Artificial Constructs – Engineered for deep-sea deployment, capable of mimicry and autonomous function.
• Non-Physical Entities – Manifestations of energy or information given temporary form.

▶︎ MORPHOLOGY
Residents exhibit varied and possibly non-standardized morphology, suggesting either multiple subspecies, specialized castes, or modular/biological-machine hybridization. Reported and recovered forms generally fall into four primary classifications:

I. Cephalomorphic
Biologically adapted to deep-ocean pressure, darkness, and stealth; highly intelligent marine analogs.

• Fluid, boneless bodies with radial symmetry
• Tentacular extensions used for motion, manipulation, or sensing
• Chromatophore-like surfaces capable of shifting color, texture, or luminescence
• Eye structures resembling cuttlefish or octopus — large, forward-facing, capable of polarization or multi-spectrum vision
• May include a central body “core” surrounded by a semi-transparent mantle

II. Plasmorphic / Amorphous
Possibly advanced Residents, field-manipulating entities, or projections of higher-dimensional structures into 3D space.

• Shape-shifting or non-rigid form with gelatinous or liquid structure.
• Movement by pulsed expansion, vortex locomotion, or fluidic compression.
• Surfaces may shimmer, ripple, or phase in and out of visual range
• Edges may appear poorly defined, constantly in motion or blur

III. Exoskeletal / Biomechanical
Possibly artificial lifeforms, autonomous extensions of a larger Resident presence, or biomechanical hybrids.

• External symmetry and defined limbs or fins; surface may resemble insectoid, crustacean, or polymer-based materials
• Segmented appendages with integrated tools, emitters, or sensors
• May produce harmonic vibrations, light pulses, or internal glow from within transparent casings
• Often mistaken for Fast Movers, as they resemble unmanned underwater vehicles (UUVs)

IV. Anthropomorphic
Resembling the human form in basic structure and proportion, though exhibiting significant physiological and anatomical deviations. This class is characterized by bilateral symmetry, upright bipedal posture, and cranial dominance.

• Short, slender stature, typically 3.5 to 5 feet tall (1–1.5 meters).
• Thin, narrow shoulders, with no visible musculature.
• Smooth, grayish, non-porous skin, sometimes metallic or pearlescent, possibly synthetic or biologically advanced.
• Long arms, sometimes reaching below the knees. Three to five fingers, often with no visible nails or joints. Fingers may taper unnaturally or end in small pads. Legs are narrow and short. |
• Small and narrow torso, rarely any sign of ribs, gender differentiation, or external organs, interpreted as asexual, cloned, or post-biological.
• Disproportionately bulbous head relative to the body, with a long and thin neck, appearing too fragile to support the head indicating internal support or gravity compensation.
• Large, black, almond-shaped eyes with no visible sclera or pupils.
• Slits or slight indentations for a nose, rarely observed actively breathing
• Small horizontal mouth, with no visible lips, teeth, or vocalization mechanism.
• Ears usually absent, or represented as tiny openings or recessed features.
• Smooth, gliding, deliberate bipedal locomotion. Some reports describe floating rather than walking.

Several variations of anthropomorphic Residents have been reported:

• Tall: Often described as 6–7 feet tall, authoritative, possibly a commander or supervisory caste.
• Hybrid: Appear more human-like, with skin tone variations, visible pupils, or more expressive facial features.
• Drone: Engineered entities or avatars for a distant intelligence.

KEY MORPHOLOGICAL FEATURES (Cross-Type)

FAST MOVERS

Fast Movers are objects or craft under direct or indirect control of Residents. They exhibit extreme motion characteristics, are unbound by known physical constraints (gravity, inertia, electromagnetism), and appear to violate our understanding of cause and effect, locality, or time. Their manifestations might be partial or distorted, appearing as glowing orbs, disappearing craft, or vanishing beings that seem inconsistent with material objects.

• These may be semi-intelligent agents rather than piloted craft, possibly comprising a distributed intelligence gathering system.
• Swarms of Fast Movers can appear biological or mineral in structure, avoiding detection and carrying out surveillance, repair, or sampling functions.
• Fast Movers may mimic fish, bioluminescent organisms, or ambient sounds to blend seamlessly into the environment.

▶︎ OPERATIONS
Documented Fast Mover activity has been categorized into three primary operational modes based on environmental interaction and mobility across domains. These classifications reflect observed behavior patterns and are intended to assist with threat assessment, reporting accuracy, and the development of tailored response protocols.

1. Submerged
   Confined to underwater domains (littoral, pelagic, benthic). Never observed to breach surface or enter air.

2. Transmedium
   Capable of moving seamlessly between air and water, often with no splash or disturbance.

3. Amphibious
   Observed operating in water and making contact with land or structures, such as beaches, ships, and docks.

▶︎ PROPULSION AND MOTION CHARACTERISTICS
Fast Movers exhibit distinct kinematic signatures suggestive of advanced manipulation of inertial, gravitational, or fluidic forces. Their movement often defies hydrodynamic expectations, with abrupt changes in velocity, seamless transmedium transitions, and low acoustic profiles. The following categories summarize observed motion behaviors:

Linear-Vectored
Moves at high speed, in a hydrodynamic manner, but with abrupt, precision-controlled changes in heading or velocity that generate no acoustic signature due to flow noise, control surface turbulence, or thrust.

Oscillatory
Exhibits subtle, rhythmic undulations or pulsing motion resembling propulsion through vibration or waveform displacement commonly seen in stationary hover or slow drift.

Stationary / Fixed-Point
Maintains perfect spatial stability in open water or turbulent environments, often for extended periods, without anchoring, thrust vectoring, or mechanical station-keeping.

Jump / Displacement
Appears to vanish and reappear instantaneously or relocate between two points with no observable travel path or propulsion signature, often accompanied by localized sensor anomalies.

Flow-Adaptive
Aligns with and rides dynamic ocean currents or thermohaline flows with minimal energy signature, suggesting advanced environmental awareness or integration.

▶︎ MORPHOLOGY / VISUAL FORM
Fast Movers display a wide range of visual geometries, with no standard shape, scale, or surface signature. Observed forms range from highly symmetric constructs to organic, seemingly biomimetic structures, many of which exhibit shape-shifting, refractive, or light-absorbing characteristics.

Spherical
Smooth, featureless, and capable of high-speed multidirectional movement, spherical Fast Movers exhibit controlled buoyancy and often emit low-frequency harmonic tones or soft internal luminescence.

Disc or Ovoid
Flattened or elliptical forms that demonstrate agile, transmedium behavior and have been observed executing sharp-angle maneuvers and sustained hover above the surface and within the water column, with no visible propulsion.

Angular/Geometric
Angular, faceted Movers resembling squares, prisms, pyramids, or polyhedrals, often metallic or refractive, display unusual light interaction properties and appear resistant to conventional sonar or EM mapping.

Amorphous or Shifting Form
Shifting in shape, opacity, and edge definition, they appear to lack rigid structure, sometimes phasing in and out of visibility and leaving behind thermal or magnetic distortions.

Organic/Biomimetic
Mimic marine life in form and motion, such as fish, cephalopods, or cetaceans, suggesting camouflage behavior or psychological adaptation, which complicates detection and classification.

▶︎ OPERATIONAL PROFILE
Fast Movers interact with their environment in ways that defy conventional aero/hydrodynamics and known propulsion mechanics. Their operational behavior suggests domain awareness, adaptive response to sensor presence, and in some cases, deliberate evasion or observation of manned and unmanned platforms.

Observed Fast Mover Behaviors:

Passive Observation – Appears to loiter, surveil, or monitor.
Active Interaction – Responds to human presence, sonar, lights, or attempts contact.
Defensive/Evasive – Retreats or hides upon detection.
Aggressive/Intrusive – Approaches or interferes with craft or sensors.
Oblivious/Unresponsive – Moves as if unaware of human presence.

▶︎ FREQUENCY OF OBSERVATION
Fast Mover incidents remain rare and unpredictable, though there is anecdotal and classified reporting indicating higher activity near nuclear-powered undersea infrastructure, nuclear-powered submarines (SSNs and SSBNs), and thermohaline anomalies. Variations in detection frequency and limitations in current sensor coverage likely distort actual Fast Mover presence.

The frequency of Fast Mover activity falls roughly into three general categories:

Persistent – Obeserved regularly in a specific location.
Sporadic – Rare or one-off encounters.
Triggered – Appear in response to specific stimuli, such as sonar pings or the presence of nuclear-powered undersea platforms.

CLUSTERS

Clusters are underwater structures or formations associated with Resident activity, typically located in deep or otherwise inaccessible subsea environments. They can be fixed or mobile, and their appearance ranges from geometric and engineered to organic or geologically camouflaged, often exhibiting anomalous energy signatures, environmental disruption, or active acoustic masking. While their precise function remains unknown, Clusters are assessed to serve as hubs for observation, staging, resource extraction, or long-duration habitation. Engagement with or proximity to a Cluster should be treated as strategically significant and operationally sensitive.

▶︎ NATURE
The sociobiological organization of Resident Clusters remains largely speculative. Several theories have emerged to explain their structural characteristics, operational functions, and integration with the surrounding environment.

Naturally Evolved Deep-Sea Habitats
Resident social structure is derived from adaptation to an extreme environment.

• Residents are indigenous beings that evolved in the deep ocean over millions of years, in parallel to surface life.
• They have evolved in geothermal vent ecosystems or deep benthic zones, beyond human detection.
• They have adapted to pressure, darkness, and chemical energy metabolism, potentially based on chemosynthesis rather than photosynthesis.

Submerged Ancient Surface-Origin Habitats
Clusters are home to an advanced race of cryptoterrestrials lost to history and surviving in oceanic exile.

• A civilization that once existed on the surface or shallow coastal zones but retreated underwater after a cataclysm (natural or self-inflicted).
• Over millennia they have developed architectural, life support, and energy systems to survive at depth.

Technologically Advanced Outposts
Clusters are nodes in mission-driven observation network.

• Residents are non-indigenous, stationed or embedded here long-term, using the oceans for concealment.
• The deep ocean offers natural shielding from orbital surveillance, EM emissions, and human interference.

Interdimensional Presence Anchored to the Ocean
Clusters are not physical structures but energy fields, phase-shifted zones, or non-Euclidean constructs.

• The ocean acts as a dimensional veil, with certain regions (trenches, thermal vents, magnetic anomalies) serving as portals or lensing points.
• Clusters may not physically exist in our reality, but manifest themselves through localized dimensional distortions.

▶︎ APPEARANCE
Clusters vary in size, geometry, and structural complexity, with some presenting as natural formations and others exhibiting clear signs of artificial patterning, symmetry, or energy emissions. Many appear partially embedded in the seabed, with only limited external architecture visible.

Biological Megastructures

• Living organisms grown or engineered into complex architectures.
• Constantly repairing and adapting; semi-sentient or possibly fully conscious.
• Integrated sensing, defense, and energy systems using biological processes.

Geothermal Integration

• Built around hydrothermal vents, using chemosynthetic energy systems or geoengineering.
• Structures shaped to channel heat, minerals, and gases into usable energy.
• Possibly camouflaged as geological features, such as false seamounts or trenches.

Phase-Shifted or Cloaked Structures

• Invisible to human sonar and radar.
• Structures that exist slightly out of phase with normal spacetime, and are detectable only through disturbances or environmental anomalies.
• Could resemble optical illusions, flickering into view under certain energetic conditions.

Crystalline or Resonant Architecture

• Composed of advanced materials that use harmonics, resonance, or quantum properties.
• May emit sound or light not perceptible to humans.
• Could function as data nodes, navigation beacons, or consciousness amplifiers.

Distributed Swarm Colonies

• Not centralized bases, but roaming clusters of biomechanical entities (like UUVs or autonomous constructs).
• Constantly in motion, hiding in the dynamic flow of ocean currents.
• Colonization is networked and mobile rather than fixed infrastructure.

Environmental Features

• EM Cilence Zones – Areas where electronics or navigation systems fail or behave erratically.
• Dead acoustic zones – Where passive and active sonar cannot penetrate.
• Unexplained bioluminescent patterns – Perhaps used for cryptic communication.
• Shifting magnetic anomalies – Consistent with phased infrastructure or exotic energy use.

INTENTIONS

While the motivations behind Resident and Fast Mover activity remain unconfirmed, recurring behavioral patterns suggest a set of operational priorities that extend beyond passive presence. This section outlines four prevailing assessments regarding intent, all of which carry strategic implications for undersea operations, infrastructure security, and broader domain awareness.

▶︎ HUMAN SURVEILLANCE
A growing body of sensor and anecdotal data suggests Residents routinely observe human maritime and subsea activity, with a particular focus on naval operations, unmanned systems, and sensor networks. This pattern indicates a sustained interest in human technological progression and operational behavior.

• Monitoring military and commercial naval traffic, particularly around subsea nuclear-powered vessels and seabed installations.
• Placement of sensors or probes on the seabed or in the water column to intercept acoustic, electromagnetic, or quantum signals.
• Close-in observation of human vessels or subsea infrastructure (e.g., underwater mining, sonar systems, or undersea bases).
• Interest in how humans respond to anomalies — perhaps to study cognition, perception, and reaction time, or as a behavioral stress test.
• Controlled appearances may be intended to elicit specific human reactions to explore consciousness modulation, perception thresholds, or neuro-linguistic feedback.
• Fast Mover sightings and/or Resident encounters may be deliberate insertions into the human cognitive landscape to test boundaries between external reality and internal experience.

▶︎ RESOURCE EXPLOITATION
Harvesting Rare Earth Elements or Exotic Materials:

• Targeting undersea hydrothermal vent fields, manganese nodules, or subduction zones for energy-rich or exotic materials.
• Possibility of exploiting materials not yet known or understood by humans (zero-point energy substrates or hyperconductive minerals).

Biological Sampling for Research or Engineering:

• Collection of DNA, proteins, or cellular structures from extremophile organisms, cephalopods, or cetaceans — possibly for biotechnology, genetic hybridization, or pharmaceutical analogues.
• Harvesting or tagging of marine life to track biological networks or neurological structures.

▶︎ ENVIRONMENTAL SAMPLING
Multiple Fast Mover and Resident encounters indicate the collection or manipulation of biological, chemical, or geological materials. Activity has been observed near hydrothermal vents, fisheries, and pollutant plumes, suggesting targeted sampling operations possibly tied to ecosystem modeling or biointeraction.

Geological and Chemical Sampling

• Collection of core samples from the seabed to study Earth’s inner composition, tectonic history, or chemical processes.
• Possible interest in radioisotopes, magnetic anomalies, or quantum-level geological phenomena.

Oceanographic Studies

• Detailed sampling of salinity, temperature, magnetic fields, and acoustic propagation to map Earth’s energy dynamics or detect global-scale shifts.

Long-Term Ecosystem Monitoring

• Observing changes in biospheric conditions, perhaps for planetary diagnostics, ecological stability, or baseline intelligence gathering.
• Tracking species migration, genetic drift, or pollution as part of a longitudinal Earth-monitoring program.

Quantum or Dimensional Probing

• If Residents are interdimensional or use non-local physics, the ocean may serve as a medium for resonance mapping, quantum entanglement testing, or dimensional anchoring.
• Areas of interest may include deep trenches, geomagnetic hotspots, or places associated with anomalous time-space phenomena.

▶︎ INFRASTRUCTURE DEPLOYMENT
Certain Cluster formations and seafloor patterns imply the existence of constructed or emplaced infrastructure. These may serve as observation hubs, energy harvesting nodes, or communication relays, and their proximity to human undersea infrastructure raises the possibility of co-use or signal interception.

Seafloor Installations

• Bases embedded in trenches, undersea caves, or volcanic systems — cloaked, phased, or shielded from detection.
• Could serve as forward operating posts, data relays, or energy harvesting nodes.

Transmedium Launch/Recovery Nodes

• Platforms from which transmedium craft enter and exit Earth’s atmosphere or dimensional planes.
• May include stealth portals, wormhole anchors, or antigravity lift systems embedded in the seabed.

▶︎ EXPERIMENTAL OPERATIONS
Some Resident activity patterns are consistent with environmental manipulation, such as controlled current redirection, acoustic propagation interference, or biological alteration. These signatures raise the possibility of experimental operations focused on bioengineering, planetary regulation, or long-term ecological shaping.

Bioengineering

• Genetic or neurological manipulation of marine species, potentially including cephalopods, cetaceans, or even human subjects.
• Behavioral tagging or stimulation — for unknown, possibly emergent intelligence studies.

Planetary Engineering

• Subtle manipulation of the undersea environment as part of a planetary stewardship, terraforming, or climate mediation program.

ENCOUNTERS

Given the unpredictable behavior and unknown capabilities of Fast Movers, all personnel are advised to adhere to strict protocols when an encounter occurs. This section outlines recommended tactics, techniques, and procedures (TTPs) to ensure operational safety, avoid provocation, and preserve the integrity of sensor and telemetry data, and is intended to support rapid assessment, controlled disengagement, and immediate reporting in accordance with SAP-SEA protocols.

Maintain Composure and Operational Discipline

• Do not engage unless directly threatened or ordered.
• Avoid rapid or aggressive maneuvering that might be interpreted as hostile.
• Maintain mission posture; treat the anomaly as a contact, not a combatant, unless ROE (Rules of Engagement) are updated.

Note: During an encounter, instrument disruption or loss of control may occur. It is unclear whether this is caused by close proximity to energy or spacetime distortions, or an intentional hostile act meant to probe or disrupt capabilities.

Record and Log All Sensor Data

• Immediately mark the contact in sonar logs and record broadband and narrowband data (including full-spectrum acoustic, magnetic, and EM signatures).
• Capture precise geo-coordinates, depth, time, and environmental conditions (temperature layers, thermoclines).
• Record crew observations, especially if visual contact is made (e.g., via periscope or UUV camera).

Note: If the object is transmedium, also record hydrostatic and surface disturbance data.

Do Not Attempt Acoustic Communication Unless Authorized

• Active sonar or pings should not be directed at the object, unless directed by command.
• Acoustic signaling should be avoided to prevent unintended provocation.

Note: Resident communication thresholds or threat perception are not understood.

EMCON and Stealth Protocols

• Minimize electromagnetic emissions, especially if the contact is behaving in an observational or mirroring capacity.
• Remain silent unless contact with higher command is essential.
• Use secure burst transmission protocols if contact is required (ELF/VLF burst or satellite relay via buoy if surfaced).

Monitor for Unusual Environmental Effects

• Ambient noise (e.g., sudden silences or unexplained broadband patterns)
• Magnetic field anomalies
• Equipment glitches or sensor malfunctions
• Crew disorientation, confusion, or psychological effects

NOTE: Report any potential cognitive, emotional, or perceptual anomalies through medical or command channels.

Rules of Engagement

• Treat Movers as non-hostile unless directly threatened.
• Do not pursue unless explicitly ordered.
• Movers engage in parallel tracking, flash lights, or emit directed acoustic bursts, treat this as possible communication, not aggression.

Debrief and Compartmentalized Reporting

• Upon return to port or secure communication window, file a compartmentalized Special Incident Report (SIR) through proper channels.
• Crew may be subject to a non-disclosure protocol, especially if the event is under classification.

NOTE: A small number of submarine crews may receive advanced briefings under SAPs (Special Access Programs) or sensitive operations frameworks.

Psychological Operations (PSYOPS) and Escalation Awareness

• Be aware that Resident/Mover behaviors may be non-intuitive, involving mirroring, delayed reactions, or symbolic gestures.
• Refrain from assigning human behaviors or motives (mirror imaging).
• Understand that no-response may be a form of Resident interaction or control.

Training and Simulation

• Regular drills involving unknown contacts, transmedium phenomena, or non-responsive underwater objects may be included in advanced undersea warfare curricula.
• Some training simulations may include intentionally ambiguous encounters to prepare commanders for situations where existing doctrine fails.

COMMUNICATION

Communication among Resident entities and between Residents and human observers remains a poorly understood, but it is critically significant component of contact scenarios. Available data suggests that Residents may employ advanced forms of acoustic signaling that are largely indistinguishable from environmental background noise. Instances of potential Human-Resident, while rare, indicate the possibility of targeted messaging, cognitive influence, or symbolic signaling, all of which merit structured observation and disciplined reporting.

▶︎ INTER-RESIDENT COMMS
Multiple factors may contribute to the elusiveness of Resident acoustic signaling. These include deliberate signal obfuscation, where transmissions are engineered to mimic ambient ocean noise or operate outside standard sensor bandwidths, as well as inherent limitations in existing detection infrastructure, which is typically calibrated for large vessels or marine mammals rather than exotic, high-frequency sources. Temporal masking further complicates detection, with signals occurring in irregular pulses or nonstandard intervals that defy conventional time-series analysis. Additionally, if the acoustic patterns are non-linear, non-repetitive, or phase-encoded, they may resist classification even by advanced machine learning or anomaly detection algorithms.

Data gathered to date suggests that Resident undersea communication may leverage any combination of the following:

Hypersonic or Ultrasonic Frequencies

• Residents may utilize frequencies above the range of human and conventional passive sonar detection (>100 kHz or even into the MHz range).
• These signals could be used to encode data, trigger devices, or interact with biological organisms.
• Many hydrophones are tuned for commercial or military-relevant ranges (~10 Hz–50 kHz); Resident signals could exist just outside or far beyond these bands.

Frequency-Hopping Acoustic Transmission

• Similar to spread-spectrum radio communications, Resident systems might rapidly switch between frequencies, making detection difficult and rendering the message indistinguishable from background oceanic "scatter."
• This method also resists jamming and interception, a hallmark of secure communication protocols.

Mimicry of Biotic or Abiotic Soundscapes
Residents may disguise their signals as naturally occurring sounds:

• Whale calls, dolphin clicks
• Seismic tremors or tectonic creaks
• Vent or bubble column emissions
• Acoustic signals could piggyback onto marine mammal vocalizations or modulate ambient soundscapes, effectively hiding in plain sight — like an audio form of camouflage.

Low-Frequency, Long-Wavelength Infrasound

• Operating at extremely low frequencies (<20 Hz), they might transmit signals that propagate across ocean basins, but blend seamlessly with natural infrasound sources like earthquakes or wave action.
• These signals could serve as broadcasts between distant Clusters or as environmental control systems influencing marine life behavior.

Acoustic Phase Coding

• Rather than relying on frequency or amplitude, Residents may encode information in phase variations or subtle wavefront distortions that evade traditional signal processing.
• These waveforms may be indistinguishable from noise unless you know the phase key or decoding algorithm.

Directional, Beamforming Emissions

• Highly focused narrow-beam acoustic projectors could direct signals to precise locations or vehicles, minimizing exposure to unintended receivers.
• Could mimic echolocation, but with data-rich content embedded within the returning pulses (like a sonar version of a QR code).

Biological-Acoustic Hybrids

• Residents may use living organisms (engineered or symbiotic) as transmitters or transducers, much like whales or squid use their anatomy to produce complex sounds.
• These organisms could generate, interpret, or relay signals, forming a biological mesh network across the seafloor or water column.

Quantum-Acoustic Coupling (Highly Speculative)

• Residents may use non-classical acoustic phenomena, such as quantum coherence in water molecules, to encode signals that manifest as faint, fleeting acoustic disturbances.
• These signals would not be persistent in time or frequency, and would appear as "quantum blips" or non-repeating patterns in the acoustic background.

NOTE: Effective detection or decoding of Resident communication may require a significant expansion of current acoustic surveillance capabilities. This includes deployment of broadband hydrophone arrays capable of simultaneously capturing both infrasonic and ultrasonic frequencies, as well as adaptive signal processing techniques tailored to non-linear dynamics and phase-space reconstruction. Interpreting such signals will likely demand a cross-disciplinary approach drawing from marine biology, oceanography, cryptography, linguistics, and bioacoustics. Critically, it may also require a reframing of ambient “noise” itself, viewing it not as interference but as potential information. Archived acoustic datasets, when revisited with these frameworks in mind, may already contain overlooked anomalies of intelligence significance.

▶︎ HUMAN-RESIDENT COMMS
No protocol exists for human-initiated communication with Resident entities. However, there are numerous reports of Human-Resident communication.

• Isolated encounters have featured sudden, directed acoustic pulses, visual signaling via bioluminescence, or cognitive effects including perceived “downloads” or induced emotional states.
• Communication may occur via telepathy, symbolism, or emotion rather than spoken language or traditional technology — reflecting a consciousness-based interface rather than physical.
• Communication events are rare and highly variable, lacking repeatable triggers or outcomes.
• The ambiguity of such interactions demands cautious interpretation, strict documentation, and a readiness to recognize potential patterns that may indicate an emergent communicative framework.

PHYSIOLOGICAL EFFECTS

Encounters with Fast Movers and/or Residents could have profound and varied physiological and psychological effects on human witnesses, especially in the unique environment of underwater operations, where isolation and sensory deprivation already tax human limits.

Drawing from real-world accounts of Fast Mover and Resident encounters, deep-sea psychology, and theoretical extrapolation, here is a breakdown of observed and potential physiological effects:

Neurological Disturbances

• Headaches, confusion, vertigo
• Disruption of fine motor control
• Electrical sensitivity, or tingling in extremities

Possible exposure to EM radiation, infrasound, or exotic field effects.

Dermal or Ocular Reactions

• Temporary blindness, flash burns, or retinal afterimages
• Skin rashes, itching, or burns, especially after exposure to glowing objects or light phenomena

Reported in some CE2 (Close Encounter of the Second Kind) cases involving Fast Movers.

Cardiovascular or Autonomic Effects

• Sudden changes in heart rate, respiration, or blood pressure
• Cold sweats, tremors, or fainting
• Potential disruption of inner ear balance

Radiological or Energetic Exposure

• Nausea or vomiting
• Low-grade radiation burns or symptoms consistent with radiation poisoning
• Equipment malfunction due to localized EM surges

Could suggest exposure to ionizing radiation, high-frequency EM fields, or unknown energetic phenomena.

Unusual Biological Changes

• Temporary enhancement of sensory perception
• Genetic alteration, such as cell mutations or mitochondrial disruption
• Altered circadian rhythms or hormonal imbalances

Contextual Factors That Could Amplify These Effects

• Depth and isolation of encounter (more extreme conditions = greater stress)
• Psychological profile of the witness (e.g., susceptibility to dissociation or suggestibility)
• Presence of acoustic anomalies, bioluminescence, or sudden silence
• Resident behavior (passive, probing, communicative, evasive, intrusive)

Post-Encounter Protocol

A post-encounter medical/intelligence debrief should include:

• Cognitive assessment to gauge memory, coherence, orientation
• EMF or radiological screening
• Medical evaluation for sensory or dermal anomalies
• Psychological support or compartmentalized observation
• Compartmented reporting, possibly under a special access program

PSYCHOLOGICAL EFFECTS

In addition to potentially serious physiological effects, encounters with Fast Movers and/or Residents could have profound psychological effects on human witnesses, especially in the unique environment of underwater operations, where isolation, pressure, and sensory deprivation already push human limits.

Cognitive Dissonance or Perceptual Breakdown
Witnessing something that defies known physics can result in:

• Confusion or denial
• Difficulty forming coherent memories
• A sense of unreality or dream-like detachment

Anomalous Memory Distortions

• Memory gaps, time loss, or conflicting recollections among crew members
• Memories that return later under unusual circumstances
• Feeling that information was neurologically “implanted” or altered

Hyper-Arousal or Presence Response

• Intense, unexplainable awareness of being observed or mentally “touched”
• Fight-or-flight activation with no external provocation
• Heightened vigilance, euphoria, dread, or awe

Altered States of Consciousness

• Sudden emotional shifts (calmness, terror, euphoria)
• Perceived telepathic communication or symbolic impressions
• Dissociation or ego dissolution, especially in proximity to energy fields or light phenomena

Post-Encounter Psychological Impact

• Nightmares, flashbacks, or obsession with the event
• Paranoia or hypervigilance (especially if met with secrecy or denial)
• In extreme cases: depersonalization, depression, or PTSD-like symptoms

Sensory & Emotional Response
Observers often report an overwhelming emotional reaction upon visual contact, including:

• Awe, dread, or reverence
• A sense of being observed or “read”
• Perceived telepathic contact or message imprinting
• Auditory hallucinations, such as harmonic tones or voices

These responses may be neurological side effects, deliberate effects, or the byproduct of higher-dimensional space-time distortional.

OPERATIONAL SECURITY (OPSEC)

In addition to standard OPSEC protocols governing undersea operations, the persistent ambiguity surrounding Resident activity and intent necessitates enhanced measures, including the use of cover stories, compartmentalization, and controlled disinformation in order to mitigate risk, prevent adversary exploitation, and prevent uncontrolled public disclosure.

▶︎ INTERNAL COMPARTMENTALIZATION

1. Need-to-Know Only

• All information related to subsea Fast Mover encounters is compartmented under a special access program (SAP). Only designated personnel (e.g., commanding officer, intel officer, specific sonar analysts) are briefed.

2. Immediate Data Sequestration

• Upon detection or encounter, sensor logs are marked "Eyes Only / Special Collection".
• Logs are segregated from standard mission data and transferred via secure channels.

3. Crew Debrief Protocol

• Crew not in the SAP are told the contact was a classified U.S. or allied undersea test platform, and warned under UCMJ Article 92 (Failure to Obey an Order) not to discuss details.

▶︎ CIVILIAN INTERACTION PROTOCOL

1. Scripted Engagement
All interactions with civilian or third-party vessels are handled with scripted responses, e.g.:
“You may have observed a sonar anomaly related to a U.S. Navy training exercise.”
“The object was likely an unmanned undersea vehicle undergoing testing.”

2. Containment of Civilian Observation
If a civilian vessel reports the encounter:

• A Navy Public Affairs Officer (PAO) is deployed to control the narrative.
• Civilian witnesses may be interviewed by NCIS or another agency under the guise of routine maritime safety inquiry.
• In rare cases, civilian data, such as sonar recordings or imagery may be confiscated.

▶︎ INFORMATION & DISINFORMATION CONTROL

1. Pre-Authorized Cover Narratives
All anomalous activity is pre-assigned a conventional explanation, selected from a list:

• False sonar returns
• Geological activity
• U.S. Navy undersea drone experimentation
• Marine mammal sonar confusion
• Classified acoustic signature testing

2. Disinformation Channels
Non-attributable leaks may be seeded in online forums and social media to muddy the waters, for example:

• Claims that sightings were part of an experimental propulsion test
• Use of pseudonymous posts to suggest misidentification of common underwater phenomena

3. Meme-ification
In the modern information landscape, some narratives may be intentionally ridiculed or memed to discredit serious inquiry, creating a buffer of plausible deniability.

▶︎ COVER STORY GENERATION (Rapid Deployment)

1. Cover Story Cell (CSC)
A dedicated communications unit generates mission-aligned, time-specific cover stories for field use.

2. Key Attributes of a Successful Cover Story
Stories are plausible but vague, non-escalatory, dismissive of further inquiry, and aligned with known naval activity in the area (e.g., ASW exercise, seismic mapping).

3. Synchronization with Public Records
Maritime traffic logs, NOTMARs (Notices to Mariners), and AIS data are updated or redacted to support the cover narrative.

▶︎ DECEPTION-BY-DESIGN IN OPERATIONAL PLANNING

1. Layered Ambiguity
Intentional use of overlapping operations (e.g., drone testing during ongoing Fast Mover activity) to create plausible confusion about what was seen.

2. Integration with Black Programs
All anomalous detections may be routed through existing black project communication structures, providing built-in obscurity.

3. Compartmentalized Exercise Naming
Use ambiguous or benign exercise names for operational files, briefings, and calendar entries.

▶︎ ESCALATION PROTOCOLS

If Compromised
If a third party gains incontrovertible data:

• Conduct damage assessment immediately.
• Initiate information dampening via allied channels, tech platforms, or legal mechanisms.
• Activate Media Engagement Protocol (MEP) to seed discrediting narratives.

If Threat Perceived

• Do not engage unless directly ordered.
• Begin passive data collection and prepare satellite or airborne ISR assets for supplementary tracking.

REPORTING

The following Resident Encounter Reporting Protocol (RERP) ensures:

• Integrity of data for scientific/military analysis.
• Containment of narrative during early response window.
• Protection of personnel from psychological harm or reputational risk.
• Strategic control over potential disclosure or engagement decisions.

▶︎ CLASSIFICATION AND SECURITY HANDLING

• All reports must be marked Top Secret / SAP-SEA (Special Access Program – Submerged Encounter Anomalies).
• Information is NOT to be shared outside cleared personnel.
• Immediate handling and transmission must follow Restricted Access Channel protocols.

Crew Guidance: Do not speculate, discuss, or record outside official channels.

▶︎ INITIAL ONBOARD RECORDING

1. Commanding Officer’s Immediate Report
Within 15 minutes of the encounter (or as soon as tactically feasible), CO should submit an encrypted Preliminary Incident Notification (PIN) to theater command via:

• Secure SATCOM (if surfaced)
• Buoy or UUV relay burst (if submerged)
• Pre-established ACOMMS channel (in exceptional cases)

2. Log and Data Tagging
All relevant sonar, acoustic, magnetic, video, or EM sensor files should be timestamped and geo-tagged, physical copies (where applicable) stored under double-lock custody until offload.

3. Witness Isolation
Crew directly involved in observation (sonar techs, control room staff, etc.) are temporarily isolated post-incident for immediate interview and psychological baseline checks.

▶︎ POST-MISSION REPORTING

1. Formal Incident Report: SITREP-77 (Subsea Anomaly)
To be filed within 24 hours of return to port or uplink window and include:

• Narrative account from CO
• Timeline of events
• Sensor logs and schematics
• Witness statements
• Environmental conditions

2. Psychophysiological Addendum
Incident Report should include a separate annex capturing:

• Any reported psychological effects (e.g., time distortion, confusion)
• Physiological anomalies among crew (nausea, fatigue, perception shifts)
• EMR exposure if suspected

3. Technical Data Package
Raw files should be delivered to Naval Intelligence via secure courier or encrypted digital channel, including:

• Acoustic spectrograms
• Magnetic anomaly logs
• Sonar beam returns and overlays
• Visual/IR camera feeds (from periscope, mast, or UUV)

▶︎ REVIEW AND ESCALATION CHANNELS

Tiered Intelligence Review
Initial triage conducted by the Deep Phenomena Unit (DPU) or equivalent. If confirmed anomalous, passed to:

• Joint Interagency Subsurface Phenomena Task Force (JISPTF)
• Advanced Undersea Threat Office

Flag-Level Notification
Reports meeting criteria for transmedium behavior, intelligence mimicry, or non-kinetic interaction are briefed to select flag officers under closed-door, SAP protocols.

▶︎ POST-INCIDENT BRIEFING & NDA ENFORCEMENT

• All crew members present during the encounter are debriefed by intelligence officers and medical staff.
• Standard Non-Disclosure Agreements (NDAs) are reaffirmed, and any deviations from reporting are documented as security violations.

▶︎ PROHIBITED ACTIONS

• Absolutely no personal logging or recording of the incident (journal entries, digital notes, private debriefs).
• No discussion with foreign or allied navies unless explicitly authorized
• No unsanctioned transmission or storage of sensor data on non-cleared systems.

CONCLUSION

Resident and Fast Mover activity remains insufficiently understood, yet its operational significance is undeniable. Observed capabilities in mobility, concealment, and environmental manipulation suggest access to advanced technologies or scientific principles beyond current human understanding. In the absence of confirmed origin or intent, all encounters must be treated with maximum discretion and strategic gravity. Existing protocols emphasize containment, passive observation, and strict information control. Until technical comprehension advances or authoritative policy guidance is issued, all contacts are to be classified as sensitive, non-engageable, and of high intelligence value. Maintain heightened situational awareness, ensure all data is preserved in full fidelity, and restrict all communications to cleared channels only.
