| Summary: | Temporal and spatial variations of phytoplankton chlorophyll a concentration together with the variations of oceanographic parameters (temperature, conductivity, dissolved oxygen and nutrient salt concentrations) were studied with an automated data acquisition system, which was newly designed and installed on board the Japanese icebreaker SHIRASE. Variations of chlorophyll a concentration across three oceanic frontal zones (Subtropical Convergence, Subantarctic Front and Polar Front) in the Indian sector of the Antarctic Ocean showed positive and/or negative correlations with the oceanographic parameters. Temporal variations of chlorophyll a concentration at a fixed point in coastal fast ice area in the Ongul Strait showed a negative correlation with nutrient salts. |
