چکیده انگلیسی
Metal concentrations, sediment properties and benthic foraminiferal assemblages were investigated in sediment cores in the SW Barents Sea, to reconstruct environmental baselines and natural variability of Atlantic Water inflow since 1800Â CE. Metal concentrations correspond to no effect levels and do not influence the foraminifera. Increased Hg and Pb was linked to inflow of Atlantic Water. The data set is considered to reflect the pre-impacted environmental baseline and range in natural variability of the study area. The foraminiferal assemblages in the SW part of the study area showed warming and presence of Atlantic Water towards 1900Â CE. The NE part of the region indicate presence of cold Artic Water influenced conditions. Between 1900 and 1980 CE, the SW region indicates reduced inflow of Atlantic Water. From 1980Â CE towards the present the assemblages of the entire study area show warming of Atlantic Water and northward retreat of the Arctic Front.
