only (Fram Strait). The western, sea ice-dominated, part of Fram Strait proved to have short, late (middle May) and time varying phytoplankton blooms. At the marginal sea ice zone of the western Fram Strait [...] warm and salty Atlantic waters, experienced earlier (end of April) and longer blooms. In the eastern Fram Strait, stratification due to solar warming proved to act as a guiding factor for the the open ocean [...] Boetius, A.

During the sixth week of expedition PS101 we are making our way home through the ice. A FRAM “superbuoy” station needs to be rescued before we leave the ice.

4 September 2016
Today we have completed our research programme at the Knipovich Ridge south of Fram Strait. We are now on the transit toward Tromsø, where we will arrive in the morning of 6 September

week was characterized by intense station work both in the West Spitsbergen Current and in central Fram Strait.

lead to study areas northwest of Bear Island, south of Spitsbergen and in the central and eastern Fram Strait.

determines the sea ice volume flux in Fram Strait region and other key areas. Results are used to quantify whether coupled sea ice ocean models are capable of reproducing Fram Strait sea ice volume fluxes correctly [...] of Arctic sea ice are changes of ice volume export rates through major gates of the Arctic, such as Fram Strait. The Sea Ice Physics group investigates to what extent ice volume loss through major export
