Nutrients depression in the blooming area of Prydz Bay, Antarctica
During the SIBEX cruise of R. V. KAIYO MARU to the Indian Sector of the Southern Ocean in 1983/84,nutrient depression in the phytoplankton blooming was observed in the innermost part of Prydz Bay (75°01.2′E, 69°01.4′S). The lowest concentrations of inorganic phosphate (0.30μg-at/l), dissolved total...

Summary: | During the SIBEX cruise of R. V. KAIYO MARU to the Indian Sector of the Southern Ocean in 1983/84,nutrient depression in the phytoplankton blooming was observed in the innermost part of Prydz Bay (75°01.2′E, 69°01.4′S). The lowest concentrations of inorganic phosphate (0.30μg-at/l), dissolved total phosphorus (1.06μg-at/l), nitrate (10.5μg-at/l) and silicate (8μg-at/l) were observed, while the concentration of dissolved organic phosphorus (0.76μg-at/l) as well as chlorophyll α (2.19μg/l) was high. These low concentrations of inorganic nutrients would be attributable to the consumption by phytoplankton. However, phosphate and silicate seem to be consumed faster than nitrate is. |
