- 論文の詳細を見る
Chlorophyll α concentration in water column under the Antarctic fast ice was measured at five stations (10-675m depths) near Syowa Station (69°00′S, 39°35′E) for the period of 13 months from January 1982 to January 1983. High chlorophyll α concentrations were seen between December and March, while peaks were observed in late January. Maximum concentration was 11.30mg chl. α/m^3. During four months of the austral summer, a rapid increase of chlorophyll α was observed in late January. This phenomenon seemed to be caused by a slight increase of temperature (>-1.73℃) and a slight decrease of salinity (<34.15). Average chlorophyll α stock in water columns was 1.05-6.72mg/m^3,at least one order of magnitude higher than that reported from the Antarctic open water.
