Abstract : This program, which has evolved over more than ten years, has had a long-term goal to document and understand chemical and biological variability in the upper water column of the world's oceans. In the final years of the project a major thrust was to develop methods that would more adequately link chemical and biological distributions in the marine environment. To this end an emphasis was placed on developing techniques and measuring photosynthetic pigment distributions as indicators of biological activity in the ocean. These investigations (1) developed and improved the methodologies for measurements of chlorophyll and carotenoid pigments, (2) improved the use of pigments as chemotaxonomic indicators, (3) investigated physical-chemical-biological interactions in frontal areas, (4) increased our understanding of the photo- adaptative strategies of marine phytoplankton, (5) documented unique and novel physiological functions for pigments, and (6) evaluated potential new and more powerful pigment analytical techniques.
