Overview

What this was about

Britt Lonneville introduced Marine Regions as the backbone for the marine geoscheme: a gazetteer of nearly 65,000 marine places with persistent MRGIDs, taken from authoritative sources and hierarchically related, openly licensed maritime boundary datasets digitised from UNCLOS legislation, and other geospatial layers such as IHO S-23 sea areas and MEOW. Marine Regions provides base data to the task group, works on development and standardisation with WoRMS, and will host and maintain the resulting units.

Why it matters. A persistent, maintained gazetteer is what makes geographic standards usable and updatable over time.

Key ideas

In the room

  • Three pillars: a gazetteer, open maritime boundary datasets, and relevant geospatial layers.
  • The gazetteer is the geographic counterpart to WoRMS, with nearly 65,000 features and MRGID identifiers.
  • Names come from authoritative sources (WGSRPD, MEOW, GEBCO, national gazetteers), mapped to one identifier.
  • Parent-child relations allow hierarchies, including alternative parents.
  • EEZs and other UNCLOS zones are digitised from legislation under CC BY and updated for new legislation, rulings and feedback.
  • Final GeoScheme units will be added to the gazetteer and available for download.

Programme abstract

Marine Regions as a backbone for the TDWG Marine GeoScheme

Britt Lonneville

Marine Regions provides a standard of marine georeferenced locations, boundaries and regions for scientific and educational purposes. At its core is a hierarchical gazetteer that serves as a geographic backbone for a wide range of applications, from biodiversity infrastructures such as the World Register of Marine Species (WoRMS), to global fisheries initiatives such as Global Fishing Watch.

Beyond place names and boundaries, Marine Regions brings together diverse geospatial ecological classifications relevant to the recording and interpretation of marine biodiversity distributions. These include global and regional frameworks, such as the Marine Ecoregions of the World (MEOW), Longhurst provinces, DFO Marine Bioregions and IMCRA Provincial Bioregions. In addition, it develops and maintains data products that are important for distribution recording, but are not always readily available or consistently managed elsewhere, including maritime boundaries such as Exclusive Economic Zones (EEZ). Marine Regions has also integrated the TDWG Terrestrial Scheme since 2015.

This experience positions Marine Regions as an active contributor to the development of the proposed TDWG Marine GeoScheme within the broader GeoSchemes framework. Its contribution is twofold: providing relevant source data, including Exclusive Economic Zones and IHO Sea Areas, and contributing technical expertise on how to build, version and maintain such a standard in a consistent and sustainable way. Once finalised, the TDWG Marine GeoScheme will be integrated into Marine Regions, where its areas will receive persistent unique identifiers (PIDs), Marine Regions Geographic Identifiers (MRGIDs), enabling stable, unambiguous citation, machine to machine linkage, and use in (biodiversity) data publication.
