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

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. ___________

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

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

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

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

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

Biological effects of marine organisms Pollutants of anthropogenic origin have also been polluting our oceans since the industrialization of the world. Coastal seas such as the North and Baltic Seas in

natural variations that would occur even if humans were absent. Information regarding the pre-anthropogenic state of the Holocene can be obtained either from proxies that record past climate and environmental

constraints for 14C-free fossil CO2 emission changes on the global and regional scale. KEYWORDS: anthropogenic 14CO2 perturbations, bomb radiocarbon, global carbon cycle, tropospheric 14CO2 data. INTRODUCTION [...] test ban treaty in 1963. Today, the transient bomb-radiocarbon signal has levelled off, and the anthropogenic input of radiocarbon-free fossil CO2 into the atmosphere has become the dominant driver of the [...] of the 14C/C ratio in global atmospheric CO2 (Levin et al. 2010; Graven 2015). This 14CO2-free anthropogenic CO2 flux from the burning of fossil fuels and cement production has increased globally by more
