MarineBasis-Nuuk has been conducting year-round monthly hydrographic water column measurements at the standard monitoring station (GF3) since october 2005. The water column profiles are obtained using a SeaBird 19Plus Profiler equipped with SeaPoint Fluorometer and Li-Cor Spherical PAR sensor. The CTD profiler and sensors are calibrated app. yearly. More information on the dataset can be found in: Mortensen et al. (2022). Multidecadal water mass dynamics on the west Greenland shelf.
