| 摘 要： | 掌握北极海水水质特征及地域分布等第一手数据对北极科考意义重大。该项研究工作是全国青少年北极科考子任务,于2017年夏季在北极斯瓦尔巴德群岛中部海域对表层海水水质特征、地域差异及相关控制因素进行了研究。选取了6个区域共40个采样点采集表层海水样本,从温度、酸碱度、电导率、溶解性总固体量、实际盐度和溶解氧饱和度等方面进行了水质特征测量分析,发现该海域6个区域在海水温度、电导率、溶解性总固体量、实际盐度及溶解氧饱和度等方面均有较大差异,而酸碱度差异不大: 北部冰区水温最低,溶解性总固体量最低,溶解氧含量较高; 西北部海湾溶解氧饱和度最高; 中部海峡溶解性总固体量最高,盐度和电导率最低; 南部海域水温最高,实际盐度和电导率最高,溶解氧饱和度最低; 东部沿海水温偏低。采样点地理位置、洋流情况、地形地貌等因素对表层海水水质均有影响。这些研究成果对补充我国在北极地区的第一手科考数据和进行深入的科考研究具有重要意义。

| Abstract: | The first hand data of Arctic Ocean water quality and region distribution are crucial for the Arctic expedition. During the process of taking part in the sub-task of National Youth Arctic Expedition, the author investigated the characters of surface sea water, including its quality, region difference and control factors in central Svalbard Islands of Arctic Region in the summer of 2017. 40 sampling sites were selected in 6 areas to collect the surface water samples, and temperature, pH, EC (electrical conductivity), PSU (practical salinity units), DO (dissolved oxygen) and TDS (total dissolved solids) were tested to analyze the water quality. The results show that there are big differences in temperature, EC, PSU, DO and TDS among the samples in these 6 areas, while the difference in pH is notbig. The northern ice region has the lowest water temperature, the lowest TDS and relatively higher DO. The northwestern bay has the highest DO. The central channel has the highest TDS value and the lowest PSU and EC. The southern area has the highest surface sea water temperature with highest PSU and EC and lowest DO. The eastern coast has relatively low water temperature. The author concluded that sampling location, ocean currents and topography of the areas have effects on the surface water quality. These achievements are of significant importance to the supply of first hand data of Arctic Ocean. |
