This page provides information about the valid indicative distribution map for the ecosystem functional group M3.7 Chemosynthetic-based-ecosystems (CBE). For older or alternative maps, see here.

Methods

Here is the methods summary for Map code and version: M3.7.web.orig v1.0.

Major occurrences of Chemosynthetic-based ecosystems was based on the distribution of hydrothermal vents on spreading plate boundaries mapped in ‘Plate lines and polygons’ data by USGS/ESRI. Occurrences were converted to 30 arc second spatial resolution. The distribution of cold seeps is poorly known and was not mapped.

Datasets

ESRI-plate-tectonics (USGS/ESRI N/D):

Source of topography and geomorphology. Resolution: variable (polygons), static. Accuracy evaluation: not found.
