Dataset specification
- Title: MarineBasis Nuuk - Water column - CTD measurements
- Description: Monthly measurements from SeaBird 19Plus Profiler equipped with SeaPoint Fluorometer and Li-Cor Spherical PAR sensor (CTD profiler is calibrated app. yearly) Water column:Water column MarineBasis Nuuk:The MarineBasis programme collects physical, chemical and biological data from the Greenland coastal zone. Work is focused in two fjord systems (Godthåbsfjord and Young Sund) both influenced by glaciers connected to the Greenland Ice Sheet.
