Summary and Itinerary
„Polarstern“ expedition ARK-XXIV/3 5 August – 25 September 2009
Reykjavik - Bremerhaven
The marine scientific programmes of he RV Polarstern expedition ARK_XXIV/3 aim to retrieve new information on the geoscientific evolution of the East Greenland margin. The experiments include deep seismic sounding profiles to unravel the deeper structure of the East Greenland margin supplemented by seismic reflection data, which map in detail the sediment structures beneath the sea floor. These lines will be acquired as far north as the ice permits and is supplemented by a small geological sampling programme.
The second focus of this cruise is the support of geological and geodetic programmes, which aim to retrieve new information from onshore East Greenland. The geological field party will try to probe lakes along the coast to gather new information on the latest glacial history and/or extent of the Greenland ice shield, the geodetic programme will measure how fast the Greenlandic main land is presently moving vertically. We expect vertical movements, which are normal for formerly glaciated continental regions like Scandinavia.
The geoscientific programme is supplemented by a water sampling, atmospheric, and bird/whale watching project.
