Primary production in the western tropical Pacific and equatorial warm waters

Third Institute of Oceanography, State Oceanic Administration, Xiamen 361005, China

摘要

摘要: 描述了对热带太平洋西部(1991年11月WOCE调查)及赤道暖水区(1992年11月至1993年2月的TOGA-COARE调查)的叶绿素a分布和初级生产力(C),及其与理化环境的关系.西部海域叶绿素a平均总量达19.79mg/m²,暖水区为2.168mg/m²;暖水区的潜在初级生产量高于西部海域,量值分别为228mg/(m²·d)和171mg/(m²·d),次表层最大值成为调查海域水体叶绿素a分布的一个明显特点.叶绿素a总量平面分布趋向表明:高生物量主要位于巴士海峡邻近、菲律宾以及伊里安岛的近岸站位,此外,在2°～4°N之间的观测区.低生物量主要位于外洋海域.生物量的分布与不同海域的物理过程变化有关,而海水涌升可能是导致温度、盐度和营养盐分布产生变化,并因而导致高生物量的一个重要的物理过程.

Abstract: Primary productions in the western tropicl Pacific and equatorial warm waters are studied in the WOCE cruise in November 1991and the TOGA-COA RE cruises from November 1992 to February 1993.It is shown that total amount of integrated chl a is 19.79 mg/m² in depth of 0~150 m and averagedaily primary production with, 171 mg/(m²·d) appears in the western tropical Pacific while higher chl a(21.68 mg/m²) and primary pr oduction [228 mg/(m²·d) ]occur in equatorial warm waters.The higher chl a is found at the coastal stations of the Philippines and Pulau Irian while lower chl a is at the offshore areas bounded by 2°~4°N.It shows that the distribution pattern of chl a biomass is related to different physical processes.Upwelling,which may have led to a high biomass, is a critical factor varying the distributions of temperature,sanility and nutrient in these areas.
