TideOutphasingBubaque_Min.tif – Raster of the differences (in minutes) in the tidal stage in relation to the tide in Bubaque (Latitude 11° 18,1’ N; Longitude 15° 50,0’ W) within a single Sentinel 2 scene.

IntertidalMask.tif – Mask of the intertidal mask of the Bijagós, calculated using the standard deviation of the Normalized Difference Water Index (NDWI) layers calculated for each pixel. Pixels with variability larger than 0.2 were considered to be in the intertidal area and were included as candidates for bathymetric estimation.

BathymetryCorrectedByTidalDelays_m.tif – Raster of the bathymetry of the Bijagós (in meters), following the correction of differences in tidal stage estimated within the Sentinel 2 scene.

ExposurePeriod_Hour.tif – Raster of the exposure period estimated from the corrected bathymetry, for an average tide in the archipelago (low water mark = 1.05 m, high water mark = 3.9 m, amplitude = 2.85 m);
