The distribution of dissolved and particulate trace metals (Fe, Mn, Cu, Ni, Zn, and Pb) was studied for the first time during the spring high flow period of the Lena River (Arctic Siberia). The results show that concentrations of dissolved metals in the river Lena during the spring high flow in June 1996 (spring freshet) were significantly higher than those reported for the rest of the year.

Abstract. A suspended particulate matter distribution against a hydrographical background was studied at the oceanographic transect across equatorial Atlantic in year 2000. An area of abnormally high volume concentrations found above Sierra Leone Rise entire water column (eastern part transect). The suggested explanation for anomaly is based on ballast hypothesis whereby solid particles are inc...
