中文摘要 | 本研究為探討臺灣沿近海域及黑潮海域之色素濃度分布,在現場利用水中光譜 儀計測表水至水深50m共12水層之向上及向下光譜輻射照度值,並採水分析各水層之葉綠 素a及總色素(葉綠素a加褐色素)濃度值。本實驗共進行四航次相測站,以葉綠素a及總色 素濃度之分布,通常往外海遞減,以及在臺灣南部及北部沿近海域兩者濃度之變動並不顯 著。在沿近海城及黑潮海域總色素濃度主要以葉綠素a為主,而且在黑潮海域中有較高之 葉綠素a:褐色素之比值,且葉綠素a與褐色素之濃度與光學深度成反比。 |
英文摘要 | Four cruises, focused on the Taiwan coastal seawater and Kuroshio water, were carried out to study the relationship between pigment and optical properties of seawater by means of in situ measurements of upwelling and downwelling irradiance using the underwater scanning spectroradiometer. This study shows the preliminary results focused on the temporal and spatial variations of chlorophyll a and total pigment off Taiwan coastal seawaters. The concentration of chlorophyll a and total pigment generally exhibited decrease with seaward direction and the variation of both concentrations in the Northern and Southern Taiwan coastal seawater was not very distinguished. No matter whether in the coastal seawater or in the Kuroshio water, the pigments of seawater were primarily dominated by the chlorophyll a. The Kuroshio water has a higher ratio of chi. a: phaeopigment than that of the coastal water. The relationship between optic depth and concentration of pigment-in the water column showed inverse proportion to each other. |
