 The current status of Arctic sea ice

Lance expedition August/September 2011

Expedition on board R/V Lance in the Fram Strait

The NPI-led, R/V Lance cruise in Aug/Sep 2011 in Fram Strait gave us an opportunity to study the sea ice in the region at the end of summer. Onboard were scientists working on sea ice and snow (geophysics and mechanics), oceanography and chemistry. Main tasks were to gather data on sea ice thickness using helicopter born EM-bird measurements, and collecting in situ data on sea ice properties on ice stations, and do an oceanographic section across the Fram Strait. In addition significant time was spent to recover and re-deploy moorings in a NPI mooring array that spans across the East Greenland Current, and has instruments that measure ice thickness at regular intervals during the whole year until recovered, in addition to oceanography.


As part of ACCESS project, we initiated studies on melt ponds on sea ice. These were observed using measurements on ice floes, but mainly using a camera-system on the helicopter, coincidently with ice thickness measurements, to investigate the extent of melt ponds on sea ice. Freeze-up commenced at the time of the cruise, and a lot of the melt ponds had already started to refreeze. Understanding of the extent of melt ponds is important since they decrease the albedo of the sea ice, and allow more solar energy to be transmitted to the ocean, which in turn can accelerate sea ice melting.


Work on melt ponds will be continued during R/V expeditions in 2012 north of Svalbard (July/Aug) and Fram Strait (Aug/Sep).


Generally there was very little sea ice in the region, except towards the east Greenland coast, where fast ice extended fairly far west. The drift ice from the Arctic Ocean was rather thin.
