coastMAP is the former marine geoportal of Helmholtz-Zentrum Hereon. It combines analyses and model data referring to seafloor conditions and the overlying water column, with a focus on the German Bight
The data collection with focus on North Sea contains different parameters describing the composition and structure of the seafloor substrate. This includes parameters characterizing the sediment type like
abstract: In grain size analysis, the proportion of particles with a diameter of less than 63 µm is commonly referred to as the mud content of a sediment sample. The mud content is an important biophysical
purpose:
The map shows the median grain size (or d50) of surface sediments in the North Sea predicted by interpolation of legacy grain size distribution data. It has been produced to aid in describing
purpose: This map shows the total organic carbon content (TOC) of surface sediments in the North Sea. It was produced by interpolation of legacy data from more than 3000 samples collected between 1960
Full grain size distributions were compiled from over 30,000 sediment samples collected by national and European surveys conducted during the past 50 years. The percentage mud content was calculated from
Full grain size distributions were compiled from over 30,000 sediment samples collected by national and European surveys between 1960 and 2014. The median grain size was determined at the 50% percentile
The map of weight percent TOC of North Sea surface sediments was derived from geostatistical interpolation of TOC measurements gained from more than 3000 samples collected between 1980 and 2014. The data
