Dataset specification

  • Title: BioBasis Nuuk - Lakes - Water chemistry etc.
  • Description: The two sampling lakes are located in the Kobbefjord catchment area in the bottom of Kobbefjord (Badesø / Kangerluarsunnguup Tasia: 64,13ºN, 51,36ºW and Qassi Sø: 64,15ºN, 51,31ºW). They are monitored monthly during the ice-free period. Monitoring include ice cover estimation, water chemistry, DOC (dissolved organic carbon), chlorophyll a, physical conditions, species composition of plankton, vegetation and fish. For further details, please refer to the newest BioBasis manual available at the website. Lakes:Lakes BioBasis Nuuk:The BioBasis programme monitors the dynamics of organisms and biological processes in the terrestrial and limnic ecosystems at Zackenberg and Nuuk. The BioBasis programme plays a central role in the development and implementation of the Circumpolar Biodiversity Monitoring Programme (CBMP) http://www.caff.is/monitoring across the Arctic.
