CTD profile and pump cast data from the Columbia River Estuary for the Columbia River Land-Margin Ecosystem Research (LMER) project from 1996-07-09 to 1998-03-06 (NCEI Accession 9800145)

Hydrophysical, hydrochemical, and other data were collected from CTD and pump casts in the Columbia River Estuary from 09 July 1996 to 06 March 1998. Data was collected as part of the Columbia River Land-Margin Ecosystem Research (LMER) Project. Data include water depths, temperatures, salinities, sigma-thetas, optical backscattering, chlorophyll a concentrations, beam attenuations, and percent transmissivities of pure water. CTD data, unless otherwise noted, were taken on the downcast and the resulting salinity and temperature profiles were used to select pump depths on the following upcast.
