Columbia River Estuary Study Taskforce

Columbia Estuary Data Development Program - Dynamics of the Columbia River Estuarine Ecosystem, Volume 2

A major goal of this report is to provide an integrated presentation of Columbia River Estuary community dynamics in relation to physical processes. This chapter presents the conceptual model used in carrying out physical-biological integration. Problems in integrating CREDDP data and considerations in model selection are described (Section 6.1).

Columbia Estuary Data Development Program - Changes in Columbia River Estuary Habitat Types Over the Past Century

This study compares information on the Columbia River Estuary from a time predating most human impacts with corresponding information derived from recent sources. Section 2, Methods and Materials, describes the selection and use of materials to achieve this comparison. Surveys conducted from 1868 to 1873 are the source of the historical materials selected.

Columbia Estuary Data Development Program - Benthic Infauna of the Columbia River Estuary

This report provides information on the benthic infauna of the Columbia River Estuary collected as part of the Columbia River Estuary Data Development Program (CREDDP). The studies were conducted by the Benthic Infauna Work Unit, Robert L. Holton, Principal Investigator, of
the College of Oceanography, Oregon State University.

Columbia Estuary Data Development Program - Bathymetric Atlas of the Columbia River Estuary

This atlas is a collection of maps from several hydrographic studies undertaken by Northwest Cartography, Inc. between 1979 and 1982 for the Columbia River Estuary Data Development Program (CREDDP), the U.S. Army Corps of Engineers Portland District, and the Corps' Waterways Experiment Station (WES). It also includes maps from surveys undertaken around three other historical time periods (1868, 1935, and 1958) by the U.S. Coast and Geodetic Survey (now the National Ocean Survey, a division of the National Ocenaographic and Atmospheric Administration).

Columbia Estuary Data Development Program - Avifauna of the Columbia River Estuary

The purpose of the Avifauna work unit within the Columbia River Estuary Data Development Program (CREDDP) was to determine the role of birds within the Columbia River Estuary. The study was divided into several phases to meet this objective. Initially, a literature review of previous avian research was conducted (Jones & Stokes Associates 1980).
