international waters
Enable an AI agent to identify a marine area's intended meaning as international waters, assess its conditions and applicable jurisdiction, and determine whether a proposed activity can proceed.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Enable an AI agent to identify a marine area's intended meaning as international waters, assess its conditions and applicable jurisdiction, and determine whether a proposed activity can proceed.
International waters is the colloquial label for maritime space beyond a coastal State's territorial sea, most strictly the high seas and the Area under UNCLOS, where no State may claim sovereignty and jurisdiction is mainly flag-State, with residual coastal-State rights in the EEZ and on the continental shelf.
It can be Classify a coordinate, footprint or route segment using dated maritime-limit evidence.; Compare a proposed transit, fishing operation, survey or cable activity against the rules applicable to its actor and location.; Identify required authorizations, notifications, reporting channels and unresolved prerequisites.; Detect entry into another maritime zone or an area subject to a relevant measure.; Assess whether sea conditions and emergency-support arrangements permit the proposed operation.; Produce an evidence-linked decision and specify when it must be reassessed..
Distinguishing features
Test the term's intended meaning before classifying the place: a high-seas classification excludes an EEZ, even though navigation freedoms also apply within an EEZ. [UNCLOS Articles 86-87](https://www.un.org/depts/los/convention_agreements/texts/unclos/part7.htm) and [Article 58](https://www.un.org/Depts/los/convention_agreements/texts/unclos/part5.htm)
Require dated maritime-limit evidence rather than treating distance from the nearest coastline as a sufficient classification test.
Classify the water column separately from the underlying seabed; do not infer the seabed's regime from the water's label.
Distinguish absence of territorial sovereignty from absence of jurisdiction: high-seas activities still engage flag-state jurisdiction and specified exceptions. [UNCLOS Articles 89-94 and 110](https://www.un.org/depts/los/convention_agreements/texts/unclos/part7.htm)
Distinguish a marine area's status from a vessel's passage rights: international navigation through a strait does not itself establish that the strait is high seas.

Characteristics
- Meaning asserted
- high seas | waters outside territorial seas | other explicitly defined usage | unresolved Prevents an ambiguous label from silently determining the applicable regime.
- Assessed spatial extent
- Coordinates or polygon with coordinate reference system, vertical coverage and positional uncertainty in metres Allows a position or route segment to be tested against the area.
- Water-column classification
- high seas | EEZ | territorial sea | internal waters | archipelagic waters | disputed | undetermined, by subarea and date Makes misclassification and mixed-zone geometries visible.
- Boundary proximity
- Nautical miles to a specified maritime limit, with uncertainty Shows whether position error or route drift could change the activity assessment.
- Assessment validity
- Assessment timestamp, evidence dates, validity interval where known, and current | stale | superseded | unknown Prevents outdated boundaries or expired measures from supporting present decisions.
- Underlying seabed regime
- Linked continental-shelf or international seabed Area model, including disputed or unresolved attribution Separates water-column uses from activities that touch or disturb the seabed.
- Activity assessment
- supported | conditional | prohibited | unresolved, for a specified actor, activity, place and time Avoids treating international waters as blanket permission for every activity.
- Applicable authority
- Named flag state, competent organization or other authority, linked to its activity-specific legal basis Identifies who can authorize, regulate, receive reports or enforce a measure.
- Operational sea conditions
- Wave height in metres, current speed in knots, wind speed in knots and visibility in nautical miles, with observation or forecast time Supports a separate judgment of practical safety.
- Applicable marine measures
- Linked fishing closures, protected-area measures, routing measures and environmental requirements with effective dates Captures restrictions that a broad zone label cannot express.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 18 findings · 28 questions.
Meaning and marine extent Establish what the label denotes and which marine space is being assessed.
International waters is an ambiguous label whose interpretation can change the entire decision.
Term interpretation
Separate the registry concept from the meaning asserted by a particular source or user.
Intended water category
Record whether the assertion concerns high seas or a broader set of waters outside territorial seas.
- Does international waters mean high seas here, or does the speaker include exclusive economic zones? definition
- Which source or explicit user definition establishes that interpretation? provenance
Spatiotemporal footprint
Locate the relevant marine area and delimit the assessment in space and time.
Assessed water volume
Represent the footprint and vertical coverage precisely enough to evaluate an operation.
- Which coordinates, reference system, depth interval and assessment date identify the waters concerned? measurement
- Does the footprint cross any maritime limit, requiring separate assessments of its parts? boundary
Maritime boundaries and seabed Determine water-column status without conflating coastal claims, navigational rights and seabed entitlements.
A single ocean position can engage different regimes vertically and competing interpretations horizontally.
Water-column limits
Evaluate the maritime limits needed to classify the area.
Boundary evidence and contestation
Record the basis, date and uncertainty of zone boundaries, preserving conflicting claims.
- Which official charts, deposited coordinates, agreements or decisions support the relevant maritime limits? provenance
- Could a competing claim, unresolved delimitation or positional uncertainty change the classification at this location? boundary
Vertical regime interface
Connect the water-column assessment to the separately governed seabed.
Seabed contact consequences
Identify when an operation requires a separate seabed assessment.
- Which seabed regime or competing entitlement lies beneath the assessed waters? boundary
- Will anchoring, drilling, sampling or cable placement require a linked seabed-rights assessment? action
Uses and jurisdiction Evaluate proposed uses against the actor's legal position and the relevant authority.
The area's label alone cannot establish permission, immunity or enforcement competence.
Activity-specific entitlements
Assess a concrete use instead of assigning unrestricted access to the area.
Proposed use conditions
Connect navigation, fishing, research and installation-related uses to their distinct prerequisites.
- What exact activity, vessel flag, operator nationality and operating period must the assessment cover? definition
- Which applicable rules support, condition or prohibit that use, and what must be verified before it starts? action
Enforcement and intervention
Identify the basis for exercising authority over an operation in these waters.
Competent intervening authority
Distinguish ordinary flag-state oversight from any separately justified intervention.
- Which authority has jurisdiction over this actor and conduct, and which instrument establishes it? provenance
- If boarding, seizure or pursuit is proposed, what specific legal basis and factual prerequisites support that intervention? action
Conservation and shared use Capture measures and interactions that constrain use of an otherwise accessible marine area.
Fishing controls, environmental obligations and interference with other uses require geographically and temporally specific assessment.
Resource and environmental measures
Find measures applicable to the activity, actor, species and area.
Applicable conservation controls
Record the reach and effective period of conservation and environmental requirements.
- Which fishing measures, protected-area measures or environmental-assessment requirements cover this activity at this time? boundary
- Which issuing instrument establishes each measure's applicability to this flag state or operator? provenance
Interaction with other users
Evaluate interference with existing marine uses and infrastructure.
Due regard and conflict
Identify the adjustments needed when an operation affects navigation, fishing, research or subsea infrastructure.
- Which shipping routes, fishing grounds, research operations, cables or installations intersect the proposed footprint? measurement
- What separation, coordination or operational changes are needed to address interference and applicable due-regard duties? action
Operational state and response Assess whether an operation is practicable and how incidents will be handled far from shore.
Legal availability does not establish safe operating conditions or timely access to assistance.
Marine operating conditions
Relate local sea conditions and warnings to the proposed activity's limits.
Operating window
Record the conditions and forecast uncertainty that determine whether the operation can proceed.
- What waves, currents, winds, visibility, ice and navigational warnings apply along the operation's footprint and time window? measurement
- Which activity or vessel limits would require delay, rerouting or suspension? action
Distress and incident coordination
Identify assistance and reporting arrangements without treating coordination areas as sovereignty boundaries.
Response access and reporting
Connect distress, pollution and other incidents to reachable responders and appropriate reporting channels.
- Which rescue coordination centre, communication channels and response assets serve this location? provenance
- For the anticipated incident, who must be alerted and what assistance can realistically arrive within the required time? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.

Regional variation
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- United States is not a UNCLOS party but treats most of UNCLOS as customary law and asserts a 12 nm territorial sea and 200 nm EEZ
- Some Latin American and African historic claims used 200 nm territorial seas before UNCLOS; residual political language still blurs EEZ and high seas
- China, some South China Sea claimants, and a few others assert security or historic rights in waters others treat as EEZ or high seas
- Mediterranean and enclosed seas: limited high-seas pockets because opposite coasts are closer than 400 nm
- Arctic: high-seas 'donut holes' (e.g. Central Arctic Ocean) plus extended-shelf claims; CAO Fisheries Agreement moratorium
- Southern Ocean: high-seas freedoms constrained by Antarctic Treaty, Madrid Protocol and CCAMLR
- Archipelagic States (Indonesia, Philippines) convert large sea areas to archipelagic waters, not high seas, with sea-lane passage
- UK/commonwealth and some others still use 'high seas' in statutes; popular English 'international waters' is broader and legally imprecise
- Which of these regional variation hold for the sense of international waters this model covers, and on what evidence? provenance
Neighbouring kinds and how to tell them apart
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- territorial sea - Coastal State sovereignty (subject to innocent passage) out to 12 nm; not international waters. Test: is the location landward of the territorial-sea outer limit measured from lawful baselines?
- exclusive economic zone (EEZ) - Coastal State has sovereign rights over resources and jurisdiction over artificial islands, marine science and environment to 200 nm, but other States retain high-seas-like freedoms of navigation and overflight. Test: resource rights vs water-column sovereignty - EEZ is not high seas (UNCLOS Art. 86).
- contiguous zone - 24 nm belt for customs, fiscal, immigration and sanitary enforcement only; not a resource zone and not high seas for those limited purposes.
- continental shelf - Seabed and subsoil rights may extend beyond 200 nm; the superjacent water may already be high seas. Test: water column vs seabed - different regimes can stack.
- the Area - Seabed beyond national jurisdiction, common heritage of mankind under ISA; not the same as the high-seas water column above it.
- internal waters / ports - Landward of baselines; no innocent-passage right as of right. Never international waters.
- international strait (transit passage) - May lie within territorial seas of bordering States; international navigation rights do not convert the water into high seas.
- global commons / ABNJ - Policy umbrella covering high seas plus the Area (and sometimes atmosphere/space by analogy); ABNJ is not a UNCLOS zone name.
- Which of these neighbouring kinds and how to tell them apart hold for the sense of international waters this model covers, and on what evidence? provenance

What the second pass must settle
- Should the registry definition adopt high seas as its canonical meaning, or retain a broader meaning that includes EEZ waters while explicitly distinguishing their regimes?
- Does an existing Vercy world model already cover this concept, requiring this registry entry to link to that publication?
- Which authoritative maritime-limit datasets provide adequate coverage, update history and representation of disputed claims for operational classification?
- How should the model resolve conflicting jurisdictional interpretations for a particular actor without presenting a disputed position as settled law?
- Which current global, regional and sectoral instruments, including measures under the BBNJ Agreement where applicable, create obligations for each assessed activity and actor?
