This page provides information about the valid indicative distribution map for the ecosystem functional group M1.3 Photic coral reefs. For older or alternative maps, see here.

Methods

Here is the methods summary for Map code and version: M1.3.web.orig v1.0.

Indicative maps of Photic coral reefs were obtained from Institute for Marine Remote Sensing et al. (2011). Occurrences were converted to 30 arc second spatial resolution.

Datasets

Corals500m (IMaRS/USF 2011):

Source of validated distribution records. Resolution: <1km2, static. Accuracy evaluation: qualitative (experts judgement).
