Abstract

We present bathymetry and hydrological observations collected in the summer of 2014 from two fjordsystems in southeastern Greenland with a multibeam sonar system. Our results provide a detailed bathymetricmap of the fjord complex around the island of Skjoldungen in Skjoldungen Fjord and the outer part of TimmiarmiutFjord and show far greater depths compared to the International Bathymetric Chart of the Arctic Ocean.The hydrography collected shows different properties in the fjords with the bottom water masses below 240min Timmiarmiut Fjord being 1–2 °C warmer than in the two fjords around Skjoldungen, but data also illustratethe influence of sills on the exchange of deeper water masses within fjords. Moreover, evidence of subglacialdischarge in Timmiarmiut Fjord, which is consistent with satellite observations of ice mélange set into motion,adds to our increasing understanding of the distribution of subglacial meltwater. Data are available through the PANGAEA website at https://doi.pangaea.de/10.1594/PANGAEA.860627.
