The overarching goal is to facilitate a politically, socially and ecologically acceptable [...] 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 of explosives in water and

for atmospheric research and geophysics purposes, the airplane has landed on the Arctic sea ice near the North Pole, and at the South Pole.

an ice shelf is born. Meteoric ice floats on sea water because of its density being smaller (910 kilograms per cubic meter) compared to the density of sea water (1028 kilograms per cubic meter). An ice [...] part of an ice sheet and floats on the ocean, but it rests on the sea floor at its fringes and on embedded islands. Contact with the sea floor slows down the seaward movement of shelf ice and thus the ice [...] formed by intensive sea ice formation in coastal polynyas (large ice-free area near the coast) flushes the ice shelf cavity (Fig. 2), causing melt rates less than 1 meter per year. Sea water at the surface

international projects on the energy and mass balance of sea ice (radiation measurements above, in and below sea ice) and on the properties of snow on sea ice. Much of his work and results are based on measurements [...] Marcel Nicolaus is a sea ice physicist and climate scientist at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) in Bremerhaven. Born in 1976 in Haan (North Rhine-Westphalia) [...] and modelling of snow on Arctic and Antarctic sea ice at the AWI and the University of Bremen in 2006. He then studied the interactions of sunlight and sea ice at the Norwegian Polar Institute in Tromsø

In 2010, the Centre for Scientific Diving of the AWI has installed an underwater experimental field North of Helgoland [...] the Arctic. The AWI contributes to COSYNA with two cabled underwater observatories in the North Sea (Helgoland) and in the Arctic (Kongsfjord Spitzbergen). Both systems are part of the Helmholtz Observatory

Over centuries the deep sea was considered as a vast, desert-like environment with low number of species. However, in recent years knowledge about biodiversity in the deep sea has started to increase and [...] life. Biodiversity in the deep sea depends among other parameters on water depth, which in turn is linked to food availability. In contrast to the past assumption that deep-sea organisms live in very stable [...] changes in a the transition zone between the northern North Atlantic and the central Arctic Ocean, and to determine the factors controlling deep-sea biodiversity, the Alfred Wegener Institute established

how the SHW interacted with past changes in sea surface temperature and how this is linked to changes in Antarctica. We aim to reconstruct precipitation and sea surface temperature on decadal to millennial [...] southern hemisphere westerly wind belt (SHW) encircles Antarctica, tracking the mid-latitude meridional sea surface temperature gradient (e.g. Lamy et al., 2010 ). The SHW is an important component of global [...] understanding of the dynamics of the SHW and temperature evolution. To this end, we investigate a north-south transect of marine and lake sediment cores spanning the range of the SHW (Fig. 1). From these
