Reference codes modelling the entity submitting a dataset to the IOTC Secretariat.

It generally corresponds to a country, but can also reference:

  • the European Union (EUR) submitting data on behalf of one of its flag states;
  • IOTC or IPTP (Indo-Pacific Tuna Programme) when historical data was available to these two institutions only;
  • an unknown data provider (NEI).

Geospatial Data

A set of code lists used to model a vessel flag / data reporting country (typically, referenced by ISO-3 code), as well as several different types of irregular Indian Ocean areas of relevance, such as the main IOTC convention sub-areas, the National Jurisdiction Areas of the coastal States, and some irregular areas of statistical relevance at national or regional level (e.g., I.R. Iran coastal sub-areas, large-scale purse seine fishery statistical areas, stock assessment areas, etc.).

The centre coordinates and the ocean area in km2 of each irregular area or regular grid are calculated with respect to the fraction of the theoretical area (potentially overlapping with the mainland) that falls within the IOTC area of competence.

Country Areas

Reference codes modelling the (undisputed) areas of all countries.

Indian Ocean Irregular Areas

These include the various irregular sub-areas in which the Indian Ocean can be subdivided, plus the various National Jurisdiction Areas (NJAs) within it, and any other irregular area defined (and used) for statistical purposes at national and regional level.

Indian Ocean Areas

Reference codes modelling other important areas in which the Indian Ocean might be split (e.g., north-western Indian Ocean, etc.).

Indian Ocean Main Areas

Reference codes modelling the two main areas in which the Indian Ocean is split (western / eastern Indian Ocean).

Indian Ocean Stock Assessment Areas

Reference codes modelling IO areas / sub-areas used for stock assessment purposes.

Indian Ocean National Jurisdiction Areas

Reference codes modelling the coastal states’ areas under national jurisdiction which are constituted of their territorial waters, contiguous zone, and Exclusive Economic Zone (EEZ).

Indian Ocean Purse Seine Data Processing Areas

Reference codes modelling the statistical areas used by the French National Research Institute for Sustainable Development (IRD) and its collaborators to produce Indian Ocean purse seine catch estimates through the T3 process.

Indian Ocean Regular Grids

These include the various types of regular grids (generally with the same height and width, in degrees) in which the Indian Ocean can be subdivided. The adopted coding scheme is built on top of of the FAO / CWP areal grid system.

1°x1° Grid

CWP areal grid system codes for all 1°x1° regular CWP grids that overlap - at least partially - with the Indian Ocean area.

IOTC Area of Competence

This includes the irregular subdivisions in which the IOTC Area of Competence can be subdivided.

IOTC Areas

Reference codes modelling all important areas in which the IOTC area of competence might be split (e.g., north-western, high-seas, NJA, etc.).
