Chemical and Biological Variability on the Upper Water Column

这项光合色素的研究是针对 了解控制生物和 上层水柱的化学变化。 意见 将继续在分配、改造 以及海洋中光合色素的降解。 研究强调：1）色素作为化学分类 标记物，2）物理-化学-生物相互作用， 锋面区; 3）海洋生物的光适应策略 浮游植物;（4）浮游动物摄食。 高性能 液相色谱（HPLC）技术已经用于 量化卟啉和类胡萝卜素的分布，浮游动物 摄食选择性和光合速率差异 色素合成 这些研究将继续在合作 与WHOI，U迈阿密，UCSB和实验室的研究人员 在苏联。 这项研究的结果将有 直接应用于美国的问题。S. JGOFS。

This study of photosynthetic pigments is directed at understanding the processes that control biological and chemical variability in the upper water column. Observations will continue to be made on the distribution, transformation and degradation of photosynthetic pigments in the oceans. Research has emphasized: 1) pigments as chemotaxonomic markers, 2) physical-chemical-biological interactions in frontal areas, 3) photo-adaptation strategies of marine phytoplankton, and 4) grazing by zooplankton. High performance liquid chromatographic (HPLC) techniques have been used to quantify porphyrin and carotenoid distributions, zooplankton feeding selectivity, and differential rates of photosynthetic pigment synthesis. These studies will continue in cooperation with investigators at WHOI, U Miami, UCSB and at laboratories in the Soviet Union. The results of this research will have direct applications to issues in the U. S. JGOFS.
