Ziel der Reise / Objectives of Cruise:
The target area of the RV Polarstern expedition ARK-XXIV/3 was the shelf and margin of Nordeast Greenland. The main objective of the geoscientific programs were to gather new information on the tectonic and glacial history of East Greenland and its ice shield. The expedition started at August 5th, in Rejkjavik (Iceland) and terminated on September 25th, in Bremerhaven. The ship sailed almost 8097 NM (15000 km) during this leg. The final position of the geophysical profiles significantly differ from the original plan. Dense pack ice north of 76?N prevented any geophysical experiments on the shelf and along the margin. To safely operate the streamer system as well as the oceanbottom seismometers, the geophysical profiles were shifted south- and eastwards.
