自1988年11月至1989年3月,对南极乔治王岛的长城湾沿岸水域中的海洋生物和环境因子进行了调查,1988年11月20日在2号站采得的冰芯中部有一层约5cm的棕色层,而1988年11月17日、20日和26日在5号站采得的冰芯样中有二层棕色层。固定冰中叶绿素a浓度范围在2.55～56.8mg/m~3之间,而且大部分含量集中在海冰的中间层中,而不象其它海区如昭和、戴维斯、凯西和麦克默多等站,大部分叶绿素a集中在海冰的底部,造成这种差别的原因、可能是由于海冰的结构和形成过程不同所致。
From November 1988 to March 1989, a survey of marine life and environmental factors in the waters off the Great Wall Bay in the island of King George of Antarctica was carried out. On November 20, 1988, there was a layer in the middle of the ice core collected at Station 2 About 5 cm brown layer, while on December 17, 20, and 26, 1988, there were two brown layers in the ice cores taken at Station 5. Chlorophyll a concentration ranged from 2.55 to 56.8 mg / m 3 in fixed ice, and most of the concentration was concentrated in the middle layer of sea ice, unlike other sea areas such as Showa, Davis, Casey and McMurdo At the station, most of chlorophyll a was concentrated at the bottom of sea ice. The reason for this difference may be due to the different structure and formation process of sea ice.
