and biological pumps of carbon will shift in future, hence whether changes in climate due to anthropogenic greenhouse gas emissions will be amplified or dampened. As physical oceanographers we are inv [...] that the Weddell Sea bottom water became warmer during the last decades, and that its content of anthropogenic CO2 increased continuously; by detailed investigations it could be shown that the densest part
disciplines at the Alfred Wegener Institute were investigating how the carbon cycle has altered by anthropogenic influence and how this affects the oceans. But it took ten years after the working group started
definitely made a solid start: in the spring of 2015 they published the freely available book Marine Anthropogenic Litter, which summarises the current state of knowledge on marine litter research. Litter on an
Arctic and Antarctic is difficult because natural variability is large, masking the evidence of anthropogenic influences. Atmospheric measurements of surface energy balance, heat and moisture fluxes, cloud
litter floating on the ocean’s surface is considerably smaller than the total amount of marine anthropogenic plastic. Based on litter surveys in 680 regions, a recent study estimates that roughly 269,000
environments provide essential supporting, regulating, provisioning and cultural ecosystem services. Anthropogenic stressors such as nutrient input from agriculture, pollution, sediment dumping, and user pressures

Wegener Institut) Oceans as a carbon store The oceans have absorbed more than a fourth of the anthropogenically generated atmospheric carbon dioxide over the past 200 years. Without this natural store the
motivation is to identify the nature of the associated aerosol sources (biogenic, geochemical, or anthropogenic) as well as source regions, and to elucidate to what extend the atmospheric signal is authentically
