ATLANTIC_CH10_Specification_2 / Digital bathymetry uncertainty covering the North Atlantic, and a representative sample area within the North Atlantic.

This product is a map of the uncertainty of available digital bathymetry measurements for the North Atlantic Ocean. This is done for a spatial resolution feasible for this large area (25km x 25km). It is designed to assess the quality of the bathymetry readings with a view to supporting assessments of future need. The product is formulated through a number of characteristics of the data including age of measurement and slope.
