Summary: | <p class="p">We present bathymetry and hydrological observations collected in
the summer of 2014 from two fjord systems in southeastern Greenland with a
multibeam sonar system. Our results provide a detailed bathymetric map of the
fjord complex around the island of Skjoldungen in Skjoldungen Fjord and the
outer part of Timmiarmiut Fjord 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 240 m in Timmiarmiut Fjord being 1–2 °C warmer
than in the two fjords around Skjoldungen, but data also illustrate the
influence of sills on the exchange of deeper water masses within fjords.
Moreover, evidence of subglacial discharge 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
