The Arctic-HYCOS project aims to collect and share hydrological data and information for the Arctic basin to enable better climate research and predictions in the Northern Hemisphere. The project serves as a vital platform for the regular collection and free exchange of Arctic hydrological data from all participating nations.

The available real-time and historical data is intended to allow researchers to:
  1. evaluate freshwater flux to the Arctic Ocean & Seas,
  2. monitor changes and enhance understanding of the hydrological regime of the Arctic region, and
  3. estimate flows in ungauged regions and develop models for enhanced hydrological prediction in the Arctic.

The map interface below displays the Arctic-HYCOS Basic Network of Hydrological Stations (BNHS) created from a selection of existing stations from the national hydrological networks in the Arctic basin. The stations can be filtered at the bottom of the map.

Each station on the map interface has a pop-up menu providing essential station’s metadata as well as a link to a webpage with the station's real-time and/or historical time series data available through the WMO Hydrological Observing System (WHOS). For each time series, any available time period of interest can be selected, plotted and downloaded in OGC NetCDF (CF conventions)OGC WaterML 2.0 or CUAHSI WaterML 1.0 formats. The time series metadata are harmonized by means of the WHOS Hydrological Ontology providing semantic interoperability among heterogeneous information sources.
