The dataset contains data on nutrients and organic matter, proxy pressure data on the upstream catchments and physical characteristics of the WISE-SoE lake monitoring stations. Waterbase contains timely, reliable and policy-relevant data collected from EEA member countries through the WISE-SoE data collection (formerly known as Eionet-Water and Eurowaternet) process. WISE-SoE data collection selects validated monitoring data from national databases and adds information on the physical characteristics of the water bodies being monitored and on the pressures potentially affecting water quality. The added value of Waterbase is that data collected through the WISE-SoE data collection process are from statistically stratified monitoring stations and groundwater bodies and are comparable at the European level. Waterbase data are primarily used in the production of the EEA's indicator-based factsheets.

The biogeographical regions dataset contains the official delineations used in the Habitats Directive (92/43/EEC) and for the EMERALD Network set up under the Convention on the Conservation of European Wildlife and Natural Habitats (Bern Convention). Changes in 2016 version: The Pannonian region of Serbia was missing in previous versions and this has been corrected in the 2016 version. Some Arctic islands which do not belong to the European part of Russia and which were erroneously included in previous versions have been removed. Biogeographical boundaries were obtained from the EU Member States and from the Emerald Network countries. These were merged together to produce a European wide map of the biogeographical regions independent of political boundaries. A number of the regions were updated during the work under Article 17 of the Habitats Directive (92/43/EEC) and in 2010 the Standing Committee to the Bern Convention adopted a number of changes according to progress in the setting-up of the Emerald Network. http://www.eea.europa.eu/data-and-maps/data/biogeographical-regions-europe-3

Revised Soil Sealing 2009, degrees of sealing 20m

Dataset contains data selected from reporting of member and collaborating countries on Ammonium, Nitrate and Nitrite concentrations in groundwater sites. Reported data have been assessed and processed by the ETC-Water and the EEA. Disaggregated records were annually aggregated and statistic value calculated. Results of quality assessment are incorporated.
