Certain special cruises of radiochemical or radioecological import were funded by the Atomic Energy Commission, as was much of the equipment for radioanalysis and stable element analysis. We gratefully acknowledge the role of these agencies in support of the research reported in the following pages. We also wish to express our thanks to the numerous students and staff who contributed to the preparation of this progress report. NOTICE The progress report that follows includes research results ranging from unproved ideas to scientific papers published during the tenure of this contract. The end of the contract year finds several facets of our work in various states ofpreparation,therefore the reader is cautioned that all except the published papers are subject to revision. iii PRINCIPAL INVESTIGATOR NormanH.

during the 20-month period from 1 July 1972 through 31 March 1974 as part of the program "Ecological Studies of Radioactivity in the Columbia River Estuary and Adjacent Pacific Ocean". This program is a continuing study supported by the Division of Biomedical and Environmental Research of the U.S. Atomic Energy Commission under ContractAT(45-1)-2227,Task Agreement 12 with Oregon State University. The report format is one which has evolved in recentyears. In this introductory section we attempt to describe the history and goals of the program and to identify the major physical facilities which are dedicated primarily to the program. This presentation
