August - October 2008 – RV Polarstern is the first research vessel in the world to circumnavigate [...] care is still fit for the trip to the ice. Birthday spends the research icebreaker in the vastness of Antarctica. The public can visit the ship in June, before it traveled the southern hemisphere for a year [...] During the Polarstern’s 29th Antarctic expedition, the researchers on board investigate the status of the Antarctic ecosystem after the polar winter, as well as the causes of differences in the development

At the positions of the [...] gy (Christina Bienhold) The Arctic Ocean is rapidly changing due to increasing temperatures and the loss of sea ice. One of the central questions about the consequences of the shrinking sea ice cover is [...] Narrative of the Cruise Cruise leg MSM29 started in the morning of June 23 in Tromsø, Norway. After two days transit, where the scientists and technicians used the time to finish the preparation of the labs

After all, many of the Atlantic [...] under the ice with a minimum temperature of minus 1.8 degrees Celsius. Life in the ocean is significantly influenced by the circulation of the water and thus by the topography of the seafloor. The map shows [...] sea ice of the Arctic in summer shimmers turquoise-blue. The thinner the ice layer at the bottom of the pond, the darker its colour because the ocean shimmers through the ice from below. At such ponds AWI

This takes advantage of the recorder now sitting just under the icy surface of the ice shelf, accessible by the Neumayer overwintering [...] Strait, respectively. See the maps to the right for of the recording sites occupied so far. Please note that not all sites are equipped with recorders at all time. Maps of the Arctic and Antarctic with [...] Tracking of Antarctic marine mammals) The aim of the PASATA project was to use time-synchronized passive acoustic recorders to localize vocalizing marine mammals in the Atka Bay area. Alongside the passive

During the first week of the expedition, we mainly [...] correlated with Matlab according to the time-stamp of the images and the time of the CTD.

As a proof of operation of the system some example images taken during the deployments should give an impression of the power of the system (Fig. 5.3.7). Table 5.3.3 List of ROSINA stations. Profile

The focus is on the current status of the biodiversity of the genus Azadinium [...] Objective The One Blue project analyses concentrations, degradation and impacts of contaminants of emerging concern (CECs) in the oceans through case studies in the Atlantic, the Arctic and the Mediterranean [...] Research objective The goal of CONMAR is to provide information on the distribution and condition of munitions in the German North Sea and Baltic Sea and to generate an understanding of the release and dispersal
