【摘要】利用我国首次在南极长城湾海域布放的极地近岸海洋环境监测系统,以2010年12月13日至2011年3月22日期间获得的监测数据为例,对该海域基本环境参数和叶绿素a含量季节变化进行了初步分析。结果表明,温度变化在观测期间总体上呈上升趋势,而受夏季陆地淡水输入的影响,盐度的总体变化趋势正好相反。观测期间温度的变化范围为0.27~2.52°C,在1月中旬和2月下旬分别出现明显峰值;盐度变化范围为33.86~34.19,在1月初、1月中旬、2月下旬以及3月上中旬出现明显的低峰值。叶绿素a含量在观测开始至12月底迅速上升,而后一直维持在一个相对较高的水平。在观测时间内分别在12月底、1月中旬和2月下旬出现峰值,最高值达4.22 μg/L。叶绿素a含量与水温存在明显的相关性。初步数据分析及与历史监测数据的对比分析表明,研发并在长城湾布放的极地近岸海洋环境监测系统作为一种新型的极地海洋环境监测工具稳定、可靠,与传统监测方法的结合可实现对南极近岸海域环境的精细监测。

【Abstract】The preliminary analysis of basic environmental and chlorophyll a concentration data in Great Wall Bay near Chinese Great Wall Station, King George Island, West Antarctica was carried out, based on the monitoring data from December 13, 2010 to March 22, 2011 by a POLAR COASTAL MARINE ENVIRONMENTAL MONITORING SYSTEM (PCMENS). Results show that, water temperature increased in general in this period, but influenced by fresh water inflow, the salinity were decreased in general. Water temperatures varied between 0.27°C and 2.52°C,and the obvious peaks occurred in middle January and late February; Salinities ranged from 33.86 to 34.19, and the marked low peaks were observed in the beginning of January, middle January, lat February and early March. Chlorophyll a concentrations increased rapidly from beginning to the end of December, and then maintained a relative higher level. Three peaks occurred in the observing period, which occurred in the end of December, middle January and late February. The maximum was 4.22 μg/L on 14 January. There was a significant correlation between chlorophyll a concentrations and water temperatures. The basic data analysis and comparison to the historical monitoring data obtained from traditional methods shows that, the PCMENS, as a new polar marine environmental monitoring tool, is successful and reliable, combined with the traditional methods, can carry out the fine environmental monitoring in the polar coastal waters.
