timing in Antarctic krill. With parts of the Southern Ocean experiencing rapid warming caused by anthropogenic driven climate change, it is of fundamental interest to understand the involvement of endogenous

pelagic key species to investigate their performance and acclimation capacity with regards to (anthropogenic) environmental change and to understand the role of these species in biogeochemical cycles. We

are currently changing more rapidly than at almost any time in Earth’s history. This is due to anthropogenic factors, which on the one hand have individual effects, but which are also mutually reinforcing

Ocean Acoustics
Due to construction work in the sea, shipping, and gas and oil extraction, the oceans are becoming increasingly louder. A comprehensive international study has now shown that this n

Climate change arises from natural and anthropogenic external forcing, as well as from variations within the climate system. Whereas synoptic to interannual variations in the climate system are well observed [...] time-scales. Estimating that variability is the basis for the detection and attribution of the anthropogenic component and determines the range of plausible future climate changes. Imprints created during

Waters of the Weddell Sea, reveal a steady CO 2 increase, of likely anthropogenic origin, as surface water, charged with anthropogenic CO 2 , is a major component with the formation of WSBW (Van Heuven [...] Heuven et al. 2011). The findings reflect the deep-sea sequestration of anthropogenic CO 2 , thus contributing to diminishing the burden of excess CO 2 in the atmosphere. The largest increase is found for NC [...] NC T in the surface layer (Van Heuven et al. 2014). Here, uptake of excess CO 2 , i.e. anthropogenic CO 2 , from the atmosphere has obviously occurred.
