Columbia River Land Margin Ecosystem Research Project Datasets

Land-Margin Ecosystem Research in the Columbia River Estuarine Turbidity Maximum (CRETM) is an interdisciplinary approach to investigating couplings between hydrological, geochemical and ecological processes within estuarine turbidity maxima. General hydrographic profiles indicate the nature of physical, biological, and particle stratification in the water column. From these data, the principle investigators determined depths to sample during pump casts. In addition, profiles of hydrographic and biophysical parameters may be used to explore potential links between or among these parameters and to verify instrument accuracy.
