Ocean profile of temperature and salinity below the ice shelf of Petermann Gletscher, Greenland, 2015 (NCEI Accession 0282239)

browse graphicPreview graphic
Ocean waters penetrate below the floating ice shelf of Petermann Gletscher about 50 kilometers from its terminus towards the grounding zone of the glacier. Hot-water drilling from the surface of the glacier provided access to the ocean below it. In August of 2015 three such access holes were drilled by the British Antarctic Survey about 3 kilometers, 16 kilometers, and 26 kilometers from the grounding zone near the center of the floating glacier. The files here contain 5 profiles in its raw and native resolution of 16 Hertz during both down- and up-cast to allow for careful investigation of both the interface between glacier and ocean and fine-structure within the ocean. A subset of the data were used and explained as Washam et al. (2019) in the Journal of Glaciology. Sediment cores were recovered at the same location and times.
