During the summer months, the bay and the nearby coastline are mainly free of sea ice and there is always open water present [...] the following criteria is given: Wind direction within a 330°-30° sector, wind velocity <2.0 m/s or >18 m/s, or CN concentrations >2500 cm -3 during summer, >800 cm -3 during spring/autumn and >400 cm

Quite seldom the wind exceeds the threshold velocity from the wind turbine (about 10 m/s ). Thus, the battery voltages became very low during polar night. Fortunately, the battery provided

By these molecules we obtain detailed information about the sea-ice distribution (sea-ice proxy, IP 25 , F7 ) and the origin of the organic matter (terrigenous and marine biomarkers) [...] with autosamplers, cold injection systems (Gerstel KAS 4) and flame-ionization detectors (FID). 2 GC/MS-Systems, consisting of Agilent 6850/ Agilent 7890 GC, Agilent 5975/ Agilent 5977 MSD, and an autosampler

Earth is felt to be the same; it causes objects to fall according to a well-known acceleration - g (9.8 ms -2 ). In reality, this g varies by a few hundred tens of thousandths of metres per second squared (unit [...] to the different ways that the masses in Earth's various rock and fluid layers - atmosphere, ocean, ice-sheet, sediments, crust, mantle, and core, are arranged with respect to each other.

The application of Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS) yielded major advances [...] environmental factors (sea ice cover, water mass characteristics, light and nutrient availability) affect not only the timing, but also the physiology and biochemistry in sea ice algae and phytoplankton. [...] from unicellular algae to higher trophic levels. In polar regions zooplankton has to cope with winter ice cover and darkness and hence with a relatively short spring/summer period of food plenty. In general

Depending on the exact parameters chosen, this results [...] constant distance from the surface (e.g. underside of sea ice) or bottom.

It was used for the first time during the Polarstern PS131 expedition and allowed the collection of valuable data in the marginal ice zone north of Svalbard. Further
