    dct:description """The database of the EU project MARS contains point data of macroinvertebrates, fish and macrophytes including hydromorphological, physico-chemical and land use information. Most biotic and physico-chemical data have been collected as part of an extensive national monitoring survey. Land use infromation (ATKIS land cover data) was GIS-based generated for fixed buffer strips with different widths and lengths. \r

More information on this dataset can be found in the Freshwater Metadatabase - MARS_14 (http://www.freshwatermetadata.eu/metadb/bf_mdb_view.php?entryID=MARS_14).""" ;
