Station and Environmental Data Sets from Pump Casts from the Columbia River Land-Margin Ecosystem Research Project from 16 June 1999 to 29 June 1999 (NODC Accession 0000420)

Chemical, phytoplankton, and other data were collected from the Columbia River estuary from 16 June 1999 to 29 June 1999. Data were collected from the R/V Robert Gordon Sproul, R/V Clifford Barnes, and fixed platforms as part of the Land-Margin Ecosystem Reaseach (LMER) and the Columbia River Estuarine Turbidity Maximum Research Program (CRETMRP). Data were collected by pump casts and include water depths, temperatures, salinities, percent transmissivities, beam attenuations, and rates of primary production per hour. Data also include concentrations of chlorophyll a, phaeopigments, particulate organic carbon, particulate nitrogen, and particulate organic nitrogen.
