Integrated Ecophysiology at the Alfred Wegener Institute. IPCC Climate Change Ocean acidification Anthropogenic climate change is altering the living conditions in the ocean more dramatically than in the past
adressed to examine the ecology of mussel beds and to survey the settlement of alien species on anthropogenic hard bottom substrates. Dives around Sylt are characterised by shallow water depths, strong tidal [...] (ESDP consultant document No 4)“. Scientific dives in the North Sea are done mainly to adress anthropogenic impacts (like the construction of windmill power plants) on the marine ecosystem. ___________
a research team led by Alfred Wegener Institute scientists investigated what long-term impact anthropogenic climate change will have on ocean eddies and their far-reaching effects. Using climate model
warming by absorbing most of the excess heat in the climate system and a large fraction of the anthropogenic carbon dioxide emissions. However, over the past years the Southern Ocean has experienced drastic
important implications for Southern Ocean phytoplankton ecology. By the year 2100, the ongoing anthropogenic emissions of carbon dioxide (CO2) will likely have increased atmospheric CO2 concentrations from

changes are also studied in such experiments. Large scale circulation changes as captured by anthropogenic tracers Contact: Michael Karcher The Arctic Ocean surface circulation is characterized by the [...] mark specific water masses on their paths through the Arctic. Such a tracer is 129 Iodine, an anthropogenic radionuclide which is dumped as waste into the Irish Sea and the North Sea by nuclear reprocessing
Antarctic natural resources is currently (still) prohibited under the Antarctic Treaty. Hence few anthropogenic acoustic sources exist in this region while the sea ice cover absorps sound more efficiently than [...] reducing ambient sound levels further.

with modeling studies, this information will be used to attribute the relative importance of anthropogenic activity and natural phenomena on the marine ecosystem and biogeochemical cycling of the Southern
summer Over the past 200 years, our planet’s oceans have absorbed more than a quarter of all anthropogenic carbon dioxide from the atmosphere. As a result, their acidity has increased by nearly 30 percent
