| Abstract: | The concentration and distribution of Chlorophyll-a in surface seawater of Chinese Great Wall Bay and its adjacent waters, Antarctica were determined once monthly, altogether three times during an austral summer period from Dec. 1993 to Feb. 1994. The results obtained show:The concentration of Chl-a is about 1. 29 mg/m3, ranging from 0. 18-6. 75 mg/m3. The concentrations are higher inside the Bay than that outside and in Ardely Bay, This situation is consistent with that respect of the water temperature of surface layer in the area surveyed. However, the time for the occurrences of high and low values of Chl-a concentration are not the same as those for water temperature.The results of analysis correlation between each of the 4 concentrations of nutrient salts and Chl-a show that there is an apparent positive correlation only between (NO2-N) and Chl-a in the sea water surveyed.It is inferred from the results obtained that the distribution and changes of Chl-a in the Bay and its adjacent waters are still interfered with by other ecological factors including activities of the heterotrophic microbes. |
