Confidence in Secchi disk depth ratio values
Confidence in Secchi disk depth ratio values, produced by EMODnet Seabed Habitats for the 2016 EUSeaMap broad-scale predictive habitat maps, and reused as an input to produce EUSeaMap 2019.
Values are on a range from 1 (Low confidence) to 3 (High confidence). Secchi disk depth confidence was calculated using the density of in situ Secchi disk sample points per 0.3 x 0.3 degree grid in the Baltic Sea.
