control on the global carbon cycle and is considered to be responsible for 40% of uptake of anthropogenic CO2, playing therefore a pivotal role in the global climate system. Southern Ocean phytoplankton

environments provide essential supporting, regulating, provisioning and cultural ecosystem services. Anthropogenic stressors such as nutrient input from agriculture, pollution, sediment dumping, and user pressures

utilised seas, and in the past centuries it has undergone significant changes as a result of anthropogenic influences. The various uses have particularly affected the sea’s ecosystems: native species and

Ocean. Thus, this system provides a unique natural model system to study the consequences of anthropogenic warming on food web dynamics and concurrent direct and indirect effects on biogeochemical cycles

shallower upper mixed layer. Secondly, there is a problem arising directly from CO 2 : As much of the anthropogenic CO 2 is taken up by the ocean, concentrations of CO2 and bicarbonate increase while the concentration

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. ___________

Marine Chemistry The Marine Chemistry team investigates the importance of natural and anthropogenic organic substances and nutrients in water and marine organisms and their significance for global material

both as free-living cells or attached to particles, the formation and dynamics of particles in anthropogenic coastal regions as well as industrial applications are another hot topic of our group. Algae-bacteria

the German Advisory Council on Global Change (WBGU). IPCC Climate Change Ocean acidification Anthropogenic climate change is altering the living conditions in the ocean more dramatically than in the past

research focus is on observations of the upper troposphere and stratosphere. With little local anthropogenic influence, the PAO is ideal for comparisons with other tropical stations and to study the impact
