Ziel der Reise / Objectives of Cruise:
1-Geophysical experiments were conducted to investigate the sedimentary structure of the Lena Trough and North Svalbard Margin. The major scientific goal was to gather further critical geophysical data to constrain the opening of the Fram Strait. For this the following types of data were collected: MCS seismics, multibeam, gravity. 2-Multinet samples have been processed to determine counts, species composition and depth distribution of planktonic foraminifera. The highest abundances of planktonic foraminifera were observed in the ice-free water in the eastern part of the transect, tending to lower values towards the Greenland margin. 3-To investigate the benthic environment in the Fram Strait. It is influenced by various biotic and abiotic factors on a geographic small scale. 4-Dredge sampling of the Lena Trough
