thesis, I have been examining the question of how this warm Atlantic water is transported from the Fram Strait to the 79°North Glacier. But no data have so far been available for the area crucial for me [...] has yet made it to this point During the first five weeks of our Polarstern trip when we work in the Fram Strait we are spellbound as we see the satellite image and observe how every day big cracks develop

Once there, the Fram would – accord- ing to his projections – be carried across [...] ships a proper send-off, complete with speeches, music and a ceremo- ny, just as was done for Nansen’s Fram expedition 126 years ago. Let’s all get our handkerchiefs ready, because giv- en all the emotions [...] expedition was planned to include twelve men and take five years to complete. On 25 June 1893 the Fram left the port of Oslo, departing for its unprecedented polar expedition. Nansen had his (wooden) research

It was interesting to observe that the boundary layer [...] boundary layer in a region of roughly 120 km times 30 km over a still sea ice covered part of the Fram Strait. The flight was very successful, the data look promising. Wed, 21 June A visit on RV Polarstern [...] very lucky in this regard. We suppose that one reason for the large sea ice cover in the Northern Fram Strait during the entire campaign was the prevailing northerly winds. Collocation with Polarstern

Polarstern travels to the Fram Strait so that the AWI oceanog- raphers can gather their observational data. The future of the Arctic Ocean will be decided in part in the Fram Strait, a region between Greenland [...] pulse of the Atlantic current system in the Fram Strait, the region between Svalbard and the northeast coast of Greenland. “There are three reasons why the Fram Strait is so important to us. Firstly, it [...] from the Fram Strait is finding its way under their ice tongues, melting them from below. We’re currently studying the 79° North Glacier to determine how this warm water travels from the Fram Strait to

deep-sea focus has been on the Arctic. In 1999, the institute established a long-term observatory in Fram Strait between Greenland and Svalbard. Today, the HAUSGARTEN observatory consists of 21 monitoring [...] temperatures are provoking rapid responses in the deep-sea ecosystem. This can already be seen in Fram Strait between Svalbard and Greenland, where the composition of the phytoplankton has changed. Whereas [...] As such, it’s quite possible that climate change will reduce diversity in the biotic communities of Fram Strait. To FAQ element How will it affect the Arctic deep sea when the sea ice continues to melt?

To quantify the variation of volume, heat and salt fluxes through Fram Strait, an array of moorings is [...] salinity in the WSC in Fram Strait were highest in the 10-year observation record. An increase of the AW spatial coverage was also observed.
