Abstract:

The seasonal variation of chlorophyll a in Great Wall Bay,Antarctica and its adjacent waters was investigated in the period from March 1988 to February 1989. The content of chlorophyll a ranged from 0.16mg/m 3 to 1.33mg/m 3.The vertical distribution of chlorophyll a was basically uniform from December 1988 to February 1989,with a mimuinum value at surface layer.The relationships between chlorophyll a content and environmental factors such as light and temperature are also discussed in this paper.
