Summary
Abstract: 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.

Purpose: The fundamental research goal is to understand how
circulation phenomena in the estuary, called
estuarine turbidity maxima (ETM), trap particles
and promote biogeochemical, microbial and
ecological processes that sustain a dominant
pathway in the estuary's food web.


Geographic Description:
The Columbia River Estuary from the mouth of the river to a site 53
miles (86 km) upstream. In 1992 a survey was conducted more than 200
km upstream.

Methodology Description:
See individual datasets.
