Greenland fjords are the gateway connecting the Greenland Ice Sheet to the coastal ocean. The rapidly increasing discharge of meltwater and ice from the Greenland Ice Sheet has complex hydrodynamic and biogeochemically impacts on the coastal marine ecosystem around Greenland, although data is still limited for most fjord systems. Therefore, six different fjord systems in Northwest Greenland were investigated in August 2016 during an interdisciplinary research cruise aboard the R/V Sanna that On aimed to describe the physical, chemical and biological variability from glaciers to the shelf. This data set consists of 55 CTD profiles that were obtained with a Seabird 19plusV2 conductivity, temperature, depth CTD) instrument. In addition to measuring pressure, conductivity, and temperature, the CTD recorded chlorophyll-a fluorescence, photosynthetically available radiation (PAR), and dissolved oxygen. The instrument was factory calibrated before the cruise. The CTD recorded all variables at 4 Hz and the raw data were processed using Seabird standard workflow to produce 0.5 m binned profiles using the downcast data only. This dataset compiles all CTD variables measured from all profiles into a single netCDF file. We would like to thank the captain and crew of R/V Sanna for excellent collaboration. The cruise was funded by the Danish Center for Marine Research and by the EU Horizon2020 funded project INTAROS.
