A mass of coastal water is a distinct and significant part of the surface waters between the baseline used to measure the width of territorial waters and a distance of one nautical mile. Correspondence report DCE: this entity corresponds to WISE’s Coastal Water Body (CWBODY) concept. It makes it possible to define environmental objectives, to assess the state of the environment and subsequently to verify the achievement of these objectives.
The next version of the Water Mass (provisional water bodies, defined for the State of Places) is planned for 2019.
The layers are distributed in a format consistent with the SANDRE data dictionary of the Water Mass Reference, version 1.3.
