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.

这项对光合色素的研究旨在了解控制上层水体生物和化学变异的过程。 将继续对海洋中光合色素的分布、转化和降解进行观测。 研究强调：1）色素作为化学分类学标记，2）额叶区域的物理-化学-生物相互作用，3）海洋浮游植物的光适应策略，4）浮游动物的放牧。 高效液相色谱 (HPLC) 技术已用于量化卟啉和类胡萝卜素的分布、浮游动物摄食选择性以及光合色素合成的差异速率。 这些研究将继续与 WHOI、迈阿密大学、加州大学圣巴巴拉分校和苏联实验室的研究人员合作。 这项研究的结果将直接应用于解决美国 JGOFS 的问题。
