Ocean properties below the ice shelf of Petermann Gletscher, Greenland, 2015-2017

Petermann Gletscher in North Greenland features the second largest floating ice shelf in the northern hemisphere. it is connected to Petermann Fjord and adjacent Nares Strait. Ocean temperature and salinities were measured from sensors placed below the 100-380 meter thick glacier ice shelf via conducting cables that connect Sea Bird Electronics SBE37sm sensors to dataloggers and Iridium communication satellites. The data originate from three discrete locations about 3 kilometers, 16 kilometers, and 26 kilometers from the grounding line of the ~50 kilometers long ice shelf. The data show that the floating ice shelf is strongly coupled to the ocean below and to Nares Strait at time scales from tidal to interannual and are published in (Muenchow et al., 2016; Washam et al., 2018; Washam et al., 2019)
