| 摘要: |
| 1985年9月，中国科学院海洋研究所对斜贯南黄海的断面(图1)进行了现场观测。该断面呈东南－西北走向，起始测站B6位于济州岛西南，终点测站Hl2位于青岛外海，全长约329.5 km。断面东南端位于南黄海暖流水附近(蓝淑芳等，1986)，中部横截黄海冷水团，西北端位于青岛水团附近，因此对该断面的调查是很有意义的。
本文着重分析研究这一南黄海斜断面的水文状况以及温度和盐度的垂直微细结构。 |

| Abstract: |
| Observations of the temperature and salinity microstructures with Mark-III CTD microprofiler were carried out by Institute of Oceanology, Academia Sinica in September 1985, along an oblique section through the Huanghai Cold Water Mass, the Qingdao Water Mass, and near by the Southern Huanghai Warm Current Water in the South Yellow Sea.
In this paper, hydrological conditions along the section, including temperature T, Salinity S, conditional density σt Brunt-V?is?l? frequence N, geostrnphic current V, Richardson number Ri and so on are separately analysed according to the data obtained with Mark-III CTD.
Microstructures of temperature and salinity along the oblique section are apparent and rich. Statistic characteristics of the temperature and salinity gradient layers, including the intension, thickness, and depth of upper and lower boundary of the gradient layers are represented in histogram and discussed. In addition, statistical parameters of the gradient layers such as the mean value, the mean-square deviation, the skewness S, and the kurtesis K are also calculated and analysed. |
