EFG FM1.3 Closed/open inlets – current maps

FM1. Semi-confined transitional waters biome

June 7, 2024

This page provides information about the valid indicative distribution map for the ecosystem functional group FM1.3 Intermittently closed and open lakes and lagoons. For older or alternative maps, see here.

Methods

Here is the methods summary for Map code and version: FM1.3.web.orig v2.0.

Marine ecoregions (Spalding et al. 2008) containing major or minor occurrences of each ecosystem functional group were identified by consulting global and regional reviews, maps of relevant ecosystems, imagery available in Google Earth and expertise of authors. Occurrences were converted to 30 arc second spatial resolution and clipped to a 20 km buffer along the coastline to exlcude inland and offshore areas of the ecoregions.

Datasets
