This page provides information about the valid indicative distribution map for the ecosystem functional group M4.1 Submerged artificial structures. For older or alternative maps, see here.

Methods

Here is the methods summary for Map code and version: M4.1.web.orig v1.0.

Marine ecoregions that include occurrences of submerged artificial structures were identified by overlaying a mapped distribution of shipwrecks (Monfils 2004) on marine ecoregions (Spalding et al. 2008). Occurrences were converted to 30arc second spatial resolution. In many cases these ecoregions encompassed other submerged structures such as energy infrastructure. To represent uncertainty, indicative distributions were mapped as minor occurrences.

Datasets

MEOW-2008 (Spalding MD et al. 2008):

Source of biogeographical range. Resolution: variable (polygons), static. Accuracy evaluation: qualitative (experts judgement).

Shipwrecks2004 (Monfils R 2004):

Processing steps used in this map are: Selection.

Map evaluation

This map is considered to be a Coarse quality map based on the following characteristics:

Concept alignment is Direct,general.

Ground observations are yes.

The accuracy evaluation Known records,undocumented.
