This database comes from different sources (monitoring programs in the period 2005-2012) aiming to create an information system on the state of water environment in the Middle Elbe basin. This information includes environmental (water, land use) and biological (phytoplankton, status of benthic macroinvertebrates and fish) elements obtained from sampling stations placed in larger rivers and lakes connected to the river network and from GIS maps in the whole catchment. The database is also used for empirical modelling of ecological status of phytoplankton and is compiled within the context of the FP7 MARS project.
More information on this dataset can be found in the Freshwater Metadatabase - MARS_15 (http://www.freshwatermetadata.eu/metadb/bf_mdb_view.php?entryID=MARS_15).
