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
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
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
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

air-supported spring expeditions, autonomous ice-tethered buoy systems like FRAM or MIDO have enabled a nearly year-round, Arctic basin-wide coverage of temperature and salinity profile observations since 2006
layer, thinner sea ice, more open water area and are very likely to experience ice-free summers in the near future. These shifts in turn alter solar irradiation, nutrient transport and plankton seasonality
in the water, driving them forward - away from the shore and due north. As a result, the ice cover near the coast is increasingly broken up, briefly leaving behind areas of open water referred to as polynyas
