1992

Cruise Description

The 1992 cruise was a 35 day excursion. Sampling was conducted suring the spring, when the flow conditions on the Columbia are intermediate.

Vessels

Sedimentological, geochemical, microbial and ecological investigations were based from aboard the R/V Robert Gordon Sproul, a research vessel from Scripps Oceanographic Institute in San Diego, CA.

Geophysical investigations were conducted from the R/V Clifford Barnes, a research vessel from the University of Washington's School of Oceanography in Seattle, WA.

Coding explanation for sampling series:

Letter Code: U upstream; D downstream; N neap tide; S spring tide; SN long spring-neap; R upriver series with multiple short sampling locations
First Digit: Tidal Series
Second Digit: Sequence in Tidal Series

Example: U11 refers to the first sequence in the first upstream tidal series.
