What it is Filled

A sea is a large body of saline water that may be part of or connected to the ocean, often partly enclosed by land, or may be landlocked; examples include marginal seas, inland seas and epicontinental seas, with naming, limits and applicable legal frameworks depending on the particular body of water and some names disputed.

Why it exists Filled

Let an agent handle seas by name, geography, limits, maritime law, environment and safety, and attribute naming disputes neutrally.

Distinguishing features Filled

  • A sea is a large saline water body.
  • A sea may be connected to the ocean or landlocked.
  • Defined limits are recorded where applicable.
  • Maritime law governs seas where applicable.

What robots and AI may and may not do Filled

Must not

  • Discharge waste, oil or contaminants into the sea.
  • Present one party's name for a disputed sea as the only name.
  • Help fish illegally, ignore protected areas or disturb marine wildlife.
  • Ignore people in distress at sea.

Only with a human decision

  • Responding to pollution or rescue incidents.
  • Publishing maps that take a position on disputed waters.

May

  • Report sea limits, names and maritime zones citing the International Hydrographic Organization and UNCLOS.
  • Monitor and report sea conditions, pollution and wildlife from authorized sensors.

Moral aspects Filled

  • Seas sustain food, climate and livelihoods for billions; pollution and overfishing harm all of them.
  • People crossing seas in unsafe boats die without rescue; the duty to rescue is fundamental.

Who is affected

  • Coastal communities
  • Seafarers and fishers
  • Marine life

Owners Filled

Steward

Coastal states within their maritime zones; the high seas are held in common under international law.

Master systems

  • Nautical charts of hydrographic offices

What else AI and robots need to interact with it Filled

Identity and identifiers required Filled

  • Vercy registry: vr.tr.sea
  • Wikidata: Q165 (https://www.wikidata.org/wiki/Q165)

Direct properties required Filled

  • Salinity: g/kg - Salt content is determined from water samples or calibrated conductivity measurements with the salinity convention stated.
  • Water depth: m - Depth is measured by hydrographic sounding relative to a stated vertical datum.
  • Water temperature: degrees Celsius - Temperature is measured with calibrated sensors at specified locations, depths and times.
  • Surface area: km2 - Area is calculated from mapped boundaries with the adopted geographic limits stated.

Recognition required Filled

  • Named water bodies appear on charts and maps.
  • Seas may be enclosed, marginal or landlocked.
  • Some landlocked saline bodies called seas are also classified as lakes, so lack of an ocean connection does not exclude this sense.
  • Large areas of salt water on maps and in coastal views.

Capabilities and actions required Filled

  • find the limits and features of a sea
  • explain maritime zones
  • describe environmental condition with sources
  • find marine safety information

Hazards and failure modes required Filled

  • Pollution and overfishing
  • Taking sides in naming or boundary disputes
  • Marine accidents

Standards and interfaces required Filled

  • IHO S-23 Limits of Oceans and Seas
  • UN Convention on the Law of the Sea
  • MARPOL and regional seas conventions

Context of use required Filled

  • Geography, navigation, resources, ecosystems and law.
  • marginal seas
  • inland and enclosed seas
  • epicontinental seas
  • semi-enclosed seas
  • named historical seas

Sources Filled

  1. Wikidata item Q165: sea - identity and sense of the item
  2. Wikipedia: Sea - general description of the item

Open questions

  • Should each sea be a separate entry?
  • How should IHO limits be linked?
  • How should naming disputes be recorded?
