Vertical mercury profile in relation to arsenic, cadmium and copper at the eastern north-atlantic ices reference station
Mercury (total mercury), arsenic, cadmium, copper and nutrient concentration profiles (fourteen depths) were obtained at the ICES (International Council for the Exploration of the Sea) reference station (46-degrees-N; 6-degrees-W) in 4 680 m of water in the northeastern Atlantic Ocean.

| Summary: | Mercury (total mercury), arsenic, cadmium, copper and nutrient concentration profiles (fourteen depths) were obtained at the ICES (International Council for the Exploration of the Sea) reference station (46-degrees-N; 6-degrees-W) in 4 680 m of water in the northeastern Atlantic Ocean. Concentrations of mercury generally ranged from 0.4 to 10 pM. The main feature of the vertical mercury profile was a broad peak between 150 and 1 500 m. Examination of the mercury profile in relation to water mass structure and comparison with nutrient and other elemental distributions suggested that its shape results from a remobilization of mercury during mineralization of sinking organic detritus combined with its intense scavenging in deeper waters. |
