Primary Production in the Arabian Sea

该项目将调查季风主导的阿拉伯海一年中的初级生产和光合参数。该项目是美国联合全球海洋通量研究项目（JFOGS）的一个组成部分，该项目被称为阿拉伯海过程研究。阿拉伯海是一个低纬度的海洋区，有强烈的和反向的季风，太阳辐射和海面温度的季节性变化相对较小。强烈的偶发性风强迫伴随着养分的巨大变化和初级生产力高的浮游植物大量繁殖。该项目的目标是：1)利用原位和甲板孵育确定初级生产的季节和空间变化模式，以便了解控制总产量和出口产量的过程；2)确定光合参数孵化的季节和空间格局，了解养分等环境协变量对这些参数的影响；3)利用生物光学模型中新确定的光合参数来改进对初级产量的估计，并将这些模型估计与我们对初级产量的直接观测结果进行比较。* * *

9312355 Barber This project will investigate primary production and photosynthetic parameters during the course of a year in the monsoon dominated Arabian Sea. The project is a component of the U. S. Joint Global Ocean Flux Study (JFOGS) effort called the Arabian Sea Process Study. The Arabian Sea is a low latitude oceanic region with strong and reversing monsoon winds together with relatively modest seasonal variability in solar radiation and sea surface temperature. The strong episodic wind forcing is accompanied by large changes in nutrients and massive phytoplankton blooms with high primary productivity. The objectives of the project are to 1) determine the seasonal and spatial pattern of variability of primary production using in situ and deck incubations in order to understand the processes that control both total production and export production; 2) determine the seasonal and spatial pattern of the photosynthetic parameters incubations to understand the effect of environmental covariables such as nutrients on these parameters; and 3) use the newly determined photosynthetic parameters in bio-optical models to improve estimates of primary production and compare these model estimates with our direct observations of primary production. ***
