Richard 14,: Epplev has established himself as one ~f ttte most iJ!fluential biological oceanographers of this century through his contributions to the fieM of phytoplankton physiological ecology and his interdisciplinary approach to oceanographic processes. Dick's ability to generalize and conceptualize, to take separate threads of research and weave them into a cohesive fi'amework, has enabled hint to use established techniques in novel appli~'ations, to define new approaches to old oceanographic questions, and to chart new paths. The nature attd quality of his work, and particularly the breadth c~'his interest and e.wertise, places hint with H.H. Gran, G.A. Riley, J.D.H. Strickland, and others who have given the field ef biological oceanography its conceptual structure. Dick's retirement in December 1989, after thirty-m'o years ~?/ progressional service to the oceanographic community, provides an opportlmi(v to reflect on his various accomplishments. In this article, his./briner Ph.D. students and postdoctoral associates briefly (and incompletely) review his contributions to oceanographic research attd the oceanographic community. While Dick built on the work ~?f earlier researchers and matt 3' others ~ 'ere cono'ibuthlg to the same topics that Di~ "k was studyhtg, due to .wace ~'onstraints only those papers authored by Dick are cited. Because Dick always strove to place his work in historical cmztext, the papers referred to below provide a key to the groundbreaking work by othepw.
