This project studies Greenlandic River Plumes as integrated signals of a rapidly changing Arctic hydrological cycle. Observed increased rates of melt on the Greenland Ice Sheet (GrIS) are expected to have a profound impact on the runoff of numerous rivers draining the ice sheet margin. River plumes are prominently visible on remote-sensing imagery, and their dimensions and reflectance characteristics can be mapped on a daily-weekly basis over the length of the MODIS satellite record, which amount to a detailed reconstruction of 10+ years. Plume characteristics are related to suspended sediment concentration patterns and freshwater melt of the GrIS. This datasetconsist of CTD - conductivity,temperature,depth measurements collected over field surveys in three different fjords in West-Greenland over 2010,2011 and 2012. The data originate from a Seabird CTD instrument, which has been casted for 5-20m along transects in each of these fjords.
