| A Spot satellite image was processed to assess the suitability of this facility for the cartography of epibenthic populations and bottom types in the Mediterranean sublittoral fringe. The area studied was on the north coast of Porquerolles island (Hyeres, SE France). The treated data were compared with mapping carried out by diving. We show that satellite remote sensing may permit a distinction between certain epibenthic populations and bottom types down to 10 m depth. Thus the usefulness of the satellite is reduced where the sublittoral is steeply shelving, as the mappable area is narrow and represented by only a few pixels, each of which tends to overlap several separate biocoenoses. The image treated was obtained in June under very favourable... |
