Distribution of nutrient salt and phytoplankton in the Antarctic Ocean
The phytoplankton standing stock and the nutrient concentration around the Balleny Islands were compared with those in the vicinity of the pack ice. The concentrations of phosphate, nitrate and chlorophyll-α fluctuated noticeably around the Balleny Islands, on the other hand, silicate concentrations...

The phytoplankton standing stock and the nutrient concentration around the Balleny Islands were compared with those in the vicinity of the pack ice. The concentrations of phosphate, nitrate and chlorophyll-α fluctuated noticeably around the Balleny Islands, on the other hand, silicate concentrations fluctuated in the vicinity of the pack ice. The concentrations of phosphate, nitrate, silicate and chlorophyll-α ranged 0.86-2.10μg-at/l, 5.0-29.6μg-at/l, 57.2-69.9μg-at/l and 0.15-2.41mg/m^3 around the Balleny Islands, respectively, and ranged 1.37-2.20μg-at/l, 26.4-28.4μg-at/l, 34.5-50.1μg-at/l and 0.098-0.323mg/m^3 in the vicinity of the pack ice, respectively. The concentrations of silicate around the Balleny Islands (mean=62.3μg-at/l) were more abundant than those of observed in the vicinity of the pack ice (mean=41.5μg-at/l). The inverse relationship between the concentrations of chlorophyll-α and those of nitrate were observed in the vicinity of the Young Island. This opposite relationship may suggest that nitrate and phosphate were uptaken by phytoplankton. The maximum concentration of chlorophyll-α was observed at 66°20'S, 162°05'E, where the dominant species were Thalassiosira gravida, Chaetoceros dichaeta and Fragilariopsis kerguelensis. |
