GIS of standard Regions for averaging data from plankton and trawl surveys with their morphometric characteristics

Shape-files with polygons of the regions by which data is summarized in the plankton dataset with information about surface areas, water volumes and centroid coordinates in each of them. These standard biostatistical regions are natural systems characterized by relatively uniform waters according to the formation of their properties in specific local geographical, geomorphological, climatic and hydrological conditions.
