through runoff from large rivers and through the distilling process of sea ice formation and melting. Nearly 11% of the global river runoff enters the Arctic, with the majority discharged to the Siberian shelves

. It offers researchers ideal conditions for studying permafrost soils in the Lena Delta – either near the station itself, or on the surrounding islands. Discover what AWI scientists investigate in the
variation of parameters and processes in the coastal transition zone. A second important observatory near Helgoland is the Margate field, which hosts a large number of moored sensor and is used for insitu
13000 m) measuring since 2011-01-15 20:05 UTC. The raw data are available at www.pangaea.de . The near real time backscatter profiles of the last 24 hours are presented here . They are processed and updated [...] The different colors mean different signal strength (cyan - low, blue - medium, red - high). The near real time cloud heights are not used automatically for the synoptic observations but used as help
made available on our DynAMo homepage. This will allow everybody at any given time to access the "near-realtime" data sent by the buoy in Beagle Channel. Picture gallery: the first buoy is ready to be
Based on the results, turbulence parameterizations have been developed for strong convective flow, for near-surface fluxes over sea ice in the inner polar ocean regions and over the marginal sea ice zone with [...] Impact of sea ice morphology on energy and momentum transport Marginal sea ice zone (Fram Strait, near Svalbard) with drifting floes and small ridges at the floe edges. (Photo: Alfred-Wegener-Institut) [...] the differences between surface temperatures of open water and sea ice and their difference to the near-surface air temperatures are large enough to generate convective turbulence in the lower atmosphere

Some square box are equipped with a removable front plate to obtain a undisturbed section of the near-surface sediments. A box corer samples a comparable large area of the sediment surface (50 x 50 cm)
