About coastMap


The marine geoportal coastMap of the Institute of Coastal Research at the Helmholtz-Zentrum Geesthacht provides access to existing geodata and information products of the HZG and its partner institutions. It combines analyses and model data relevant to seafloor conditions and those in the overlying water column and the atmosphere with a focus on the North Sea.

Matters of marine and environmental relevance have stimulated increasing interest by media and the public. Therefore coastMap targets different user groups: experts, professionals of other disciplines and the interested public. On the basis of modern IT functionalities the data and information are readily accessible and mostly free for download.

Research activities of the scientists are the starting point for scientific information that is channeled into knowledge for the management in the coastal zone and the marine environment. This includes the definition of a good environmental status, or to examine management options. Therefore activities were often co-designed with authorities and institutions in line with HZG's mandate and motto "Wissen schafft Nutzen".

The following geodata and information products and components are provided to users:

  • Data from field expedictions and laboratory work of the HZG and its partner institutions
  • Coupling with World Data Center PANGAEA (for obtaining a DOI for data sets)
  • Innovative Array Database Management System
  • Ongoing and updated map gallery
  • Linking to Geographical Information Systems (GIS)
  • Edited accounts of scientific topics in scientific "Spotlight" format
  • Linking of Story contents and the coastMap data and visualisation tools
  • Interactive map material and figures

coastMap is a sibling of the existing showcases of HZG's Institute of Coastal Research COSYNA (Coastal Ocean Observatory of the Unit KO) und coastDat (Modell System of the Unit KS).
