This is a meta-database bringing together information about lake, stream and river sites for which there are long-term time series data. The meta-data include details of chemical, physical and biological series collected of varying length of time. The monitored sites have been funded under a range of different sources and cover various time periods. This is not a single monitoring network but includes a mixture of individual sites and co-ordinated networks. More information on this dataset can be found in the Freshwater Metadatabase - BF47 (http://www.freshwatermetadata.eu/metadb/bf_mdb_view.php?entryID=BF47).
