| Abstract: |
| Based on the field data obtained during summer cruises in 2006, the overall perspective of chemical and hydrographic characteristics of the Yellow Sea Cold Water Mass (YSCWM) are discussed through the cross-YSCWM transect profiles and horizontal distributions of hydrological and chemical variables, with emphasis on the differences between the northern Yellow Sea Cold Water Mass (NYSCWM) and the southern Yellow Sea Cold Water Mass (SYSCWM). The results show that YSCWM is characterized by low temperature (<10℃) and dissolved oxygen (DO) concentration, high salinity (>32.0) and nutrient concentrations. Compared to the SYSCWM, the NYSCWM possesses lower values of temperature, salinity and nutrient concentrations but higher values of DO. Also its smaller variation ranges of variables (except for temperature) demonstrate that NYSCWM is more uniform than that of SYSCWM. In addition, thermocline is more intensive in the SYSCWM than that of NYSCWM. Furthermore, DO and Chl a maxima appear at the depth of 30 m in the SYSCWM, while these phenomena are not obvious in the NYSCWM. |

| 基于2006年夏季在黄海获得的现场调查数据,本文深入讨论了生源要素和水文要素在黄海冷水域的平面分布及其在纵穿黄海冷水团断面上的垂直分布特征,并着重分析了黄海冷水团水文和化学要素的空间异质性。结果表明:黄海冷水团具有低温(<10℃)、低氧、高盐(>32.0)和高营养盐的特性。相比于南黄海冷水团,北黄海冷水团具有相对较低的温度、盐度和营养盐含量,而溶解氧和叶绿素含量则相对较高。各要素在北黄海冷水团中较小的变化范围表明北黄海冷水团内部水体混合较南黄海冷水团更为均匀,而南黄海冷水团的跃层更强。此外,在南黄海的30m层附近,溶解氧出现垂直分布中的最大值并伴有SCM现象,而在北黄海中这种现象不明显。 |
