摘要：The marine record of the Independence–Danmark fjordsystem extending out to the Wandel Hav in eastern NorthGreenland (Fig. 1A) is little known due to the almost perennial sea-ice cover, which makes the region inaccessiblefor research vessels (Nørgaard-Pedersen et al. 2008), andonly a few depth measurements have been conducted inthe area. In 2015, the Villum Research Station, a new logistic base for scientific investigations, was opened at StationNord. In contrast to the early exploration of the region, itis now possible to observe and track the seasonal characterand changes of ice in the fjord system and the Arctic Oceanthrough remote sensing by satellite radar systems. Satellitedata going back to the early 1980s show that the outer partof the Independence–Danmark fjord system is characterised by perennial sea ice whereas both the southern part ofthe fjord system and an area 20–30 km west of Station Nordare partly ice free during late summer (Fig. 1B). Hence,marine-orientated field work can be conducted from thesea ice using snow mobiles, and by drilling through the iceto reach the underlying water and sea bottom.
