Columbia Estuary Data Development Program - Zooplankton and Larval Fishes of the Columbia River Estuary
Zooplankton and larval fish data were collected by the University of Washington in 1980-81 as part of the Columbia River Estuary Data Development Program. Oregon Department of Fish and Wildlife analyzed these data.
Columbia Estuary Data Development Program - Water Column Primary Production in the Columbia River Estuary
This report on water column primary production in the Columbia River Estuary was prepared for the Columbia River Data Development Program by Drs. Bruce E. Frey and Lawrence F. Small of the College of Oceanography, Oregon State University, Corvallis, Oregon, and Dr. Ruben Lara-Lara, of the Centro de Investigacion Cientifica y Educacion Superior de Ensenada, Ensenada, Mexico.
Columbia Estuary Data Development Program - Tidal Marsh Plant Production in the Columbia River Estuary
The Emergent Plant Primary Production Work Unit of the Columbia River Estuary Data Development Program (CREDDP) describes the species composition, standing crop, and primary production dynamics of the tidal marsh vegetation found within the estuary. An estuary-wide field reconnaissance conducted in October 1979 confirmed the floristic diversity of Columbia River Estuary tidal
Columbia Estuary Data Development Program - Sedimentary Processes and Environments in the Columbia River Estuary
This report summarizes the results of several years of research into the sedimentology of the Columbia River Estuary.
The Marine Mammal Investigations team of the Washington Game Department began an extensive research program in 1980 to document marine mammal populations of the region and document their relationship to fisheries of the area. The overall research program has received funding from multiple sources, including: National Marine Fisheries Service, the U.S.
This index is the result of a cooperative effort on the part of most of the research contractors of the Columbia River Estuary Data Development Program (CREDDP). The structure of the document and the introductory material are the work of Howard Mercier, CREDDP Data Management contractor.
The research reported in the following two volumes was funded primarily by CREDDP in two parts. The first part of the study employed the U. S. Army Corps of Engineers Waterways Experiment Station Implicit Flooding Model (WIFM). Thanks are due to Lee Butler of WES for supplying the original code for WIFM.
Columbia Estuary Data Development Program - Guide to the Use of CREDDP Information For Environmental Assessments
The Columbia River Estuary Data Development Program (CREDDP), a federally-funded research program, began in 1978 and was completed in 1984. The purpose of the program was to provide a foundation of scientific knowledge about the estuary and to provide information useful in managing land and water resources through the public planning and permitting processes.
