The Exceptional Oder Flood in Summer 1997- The Fate of Nutrients and Particulate Organic Matter in the Baltic Sea

摘要

The distribution of dissolved inorganic nutrients, particulate organic matter and phytoplankton pigments in the Oder plume was investigated at peak discharge of the Oder River during the exceptional flood event in summer 1997. Mixing diagrams of dissolved inorganic nutrients (NO_3~-, PO_4~4-, SiO_4~4-) reveal a nearly com- plete removal of nitrate during the first steps of estuarine mixing, whereas phosphate and silicate were still available over the entire salinity range.
