中文摘要 | 南海與蘇祿海的營養鹽垂直分佈有不同的特性,兩虛的表水幾乎都缺營養鹽。南 海水的營養鹽濃度愈深愈高,而蘇祿海的營養鹽在 400m 深度以下濃度均一。蘇祿海的中層 及底層水是自南海的中層水經海檻流入的。營養鹽躍層在陸棚區有淺化現象,它可能是因地 轉流的調整,或是由於內波進入淺水區而抬升水層的一個短暫現象。每一測站的葉綠素濃度 值最大的水層,都在營養鹽躍層之上,且與溶解氧最大值的水層在同一深度。整層水的初級 生產力在蘇祿海的深水區最大 (195 ± 2gC . m �鴃D yr �笐� '), 高於其淺水區 (166 ± 3 gC . m �鴃D yr �笐� ) 及南海的外海區 .147±3gC.m�鴃Dyr�笐�)。整層水的浮 游植物生質量在兩海域有相似的趨勢。 |
英文摘要 | A comparison of vertical nutrient characteristics in the South China Sea (SCS) and Sulu Sea showed the typical nutrient depletion in surface water and enrichment with depth with greater maximum apparent in the SCS relative to the uniform behavior of nutrients below 400 m in the Sulu Sea. This may be explained by sill inflow of SCS intermediate waters that supplies intermediate and bottom waters of the Sulu Sea. Shallowing of the nutricline on the shelf may be due to geostrophic adjustment or may be pulses of upwelled water associated with shoaling of internal waves. The deep chlorophyll maximum was found above the nutricline at all stations and coincided with the maximum dissolved oxygen concentration. The depth-integrated primary production rates in the oceanic region of the Sulu Sea (195 ± 2 gC . m �鴃D yr �笐� ) was determined to be the highest followed by the shoal area (166 ± 3 gC . m �鴃D yr �笐� ) and the oceanic region in the SCS (147 ± 3 gC . m �鴃D yr �笐� ). Plankton biomass estimates integrated with depth showed similar trends for both basins. |
