| 中文摘要: |
| There is a wind-caused upwelling along the east coast of Guangdong in summer.Its central position is above the depth of 20 m, and its annual variation is quite large.In August 1982, the velocity of the upwelling was 1.2×10-3 cm/s, the vertical flux of active phophate, 1.5m mol/(m2·d); and the primary productivity, 1558 mg/(m2·d), in the area outside the bay of Jieshi.Inside the up-welling facing the shore, a phenomenon of lacking oxygen existed at the sea bottom above 5 m depth.In the area outside the upwelling center, there was a phenomenon of upward water temperature inversion.The physical and chemical characteristics in the area of the upwelling are as follows:temperature, 22.13℃; salinity, 34.19, dissolved oxygen, 3.72 ml/l; oxygen saturation degree, 74.6%; pH value, 8.14; and active phosphate, 1.10 m mol/m3. |
