    dct:description "Land-Margin Ecosystem Research in the Columbia River Estuary 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. The specific data set description is the following: Particle concentration in estuarine turbidity maxima (ETM) will have profound effects on zooplankton community structure, population dynamics, and secondary production. Pelagic and demersal copepods dominate the zooplankton in the ETM due to a combination of passive retention and active behaviors. High concentrations of phytoplankton, microbes, and protozoans in the ETM lead to high grazing rates and secondary production of zooplankton. Zooplankton may, thus, play an important role in cycling of organic matter in the ETM." ;
