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

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.

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

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

The upward speed is much slower than the downward speed (0.7 to 1.0 m/s), and measurements are performed only during the downcast. The vehicle is long and slim to achieve [...] proposed concepts winter ventilation can result in an increase in temperature and salinity, and that no ice formation is needed. This is due to the special conditions in the Greenland Sea with subsurface advection
