Última Speciation of dissolved copper within an active hydrothermal edifice on the Lucky Strike vent field (MAR, 37 degrees N) 5 Sarradin, Pierre-marie; Waeles, M; Bernagout, Solene; Le Gall, Christian; Sarrazin, Jozee; Riso, R. The objective of this study was to deter-mine the concentrations of different fractions of dissolved copper (after filtration at 0.45 mu m) along the cold part of the hydrothermal fluid-seawater mixing zone on the Tour Eiffel edifice (MAR). Dissolved copper was analyzed by stripping chronopotentiometry (SCP) after chromatographic C-18 extraction. Levels of total dissolved copper (0.03 to 5.15 mu M) are much higher than those reported for deep-sea oceanic waters but in accordance with data previously obtained in this area. Speciation measurements show that the hydrophobic organic fraction (C18Cu) is very low (2 +/- 1%). Dissolved copper is present mainly as inorganic and hydrophilic organic complexes (nonC(18)CU). The distribution of copper along the pH... Tipo: Text Palavras-chave: Mid Atlantic Ridge; Hydrothermal vent; Speciation; Dissolved copper.
