EFG FM1.1 Deepwater coastal inlets – current maps
FM1. Semi-confined transitional waters biome
This page provides information about the valid indicative distribution map for the ecosystem functional group FM1.1 Deepwater coastal inlets. For older or alternative maps, see here.
Methods
Here is the methods summary for Map code and version: FM1.1.web.map v1.0.
Known locations of fjords where selected from a global geographical gazetteer (GeoNames 2020) and the composite gazetteer of Antarctica (SCAR 1992-2020). We further selected related coastal areas from a global coastal typology (Type IV in Dürr et al. 2011) and the adjacent marine shelves to 2000 meter depth (Becker et al 2009). A composite map was created at 30 arc seconds spatial resolution in geographic projection, occurrences were then aggregated to half degree spatial resolution and reclassified as major occurrences (cells with at least one known occurrence) and minor occurrences (cells with > 5% occurrence of coastal/marine shelf areas). Minor occurrences were clipped to a 10km buffer along the coast to remove inland and oceanic areas.

Processing
Processing steps used in this map are: Thresholds :: Clipping :: Selection :: Buffering.
Map evaluation
This map is considered to be a Coarse quality map based on the following characteristics:
Concept alignment is Direct,specific.
Ground observations are indirect.
The accuracy evaluation Known records,documented,quantitative.
