terrestrial, sea ice), age and transformation processes (e.g. microbial and photo degradation). 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

during winter, when open water is more than 1000 km away from Neumayer due to sea ice formation. It is believed that the sea ice surface can also act as sea salt aerosol source, but the process itself is still [...] concentrations is characteristic for coastal Antarc­tica and is linked with the seasonality of the sea ice coverage and insolation.

The rare earth element La is a typical

station which is located on the Ekström Ice shelf, about 8 km from the Atka Bay. 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

This is due to the special conditions in the Greenland Sea with subsurface advection
