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

today we will provide some information on the work of our colleagues here on board assessing anthropogenic impacts on the marine ecosystem on our way from Bremerhaven to Fram Strait (and back) and at

surface has risen noticeably over the past decades. This warming is to a large extent due to the anthropogenic emissions of CO2 that amplify the natural greenhouse effect. Observations show, however, that

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

Global Carbon Budget - Ocean Accurate assessment of anthropogenic carbon dioxide (CO 2 ) emissions and their redistribution among the atmosphere, ocean, and terrestrial biosphere – the “global carbon budget” [...] land sink have approximately balanced. The oceans are therefore the most important net sink for anthropogenic CO 2 emissions. The ocean in the Global Carbon Budget Less than half of all CO 2 emissions remain [...] land sink have approximately balanced. The oceans are therefore the most important net sink for anthropogenic CO 2 emissions. Each year, we collect estimates of the ocean carbon sink from global ocean bi

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.
