Variable ocean conditions can greatly impact lower trophic level prey assemblages in marine ecosystems, with effects propagating up to higher trophic levels. Our goal was to better understand how varying ocean conditions influence diets and niche overlap among a suite of low- to mid trophic level predators. We studied the...
A summary of the first year of the THEMIS observation program is presented. The observations were made from November, 1968 to November, 1969. The primary measurements were time series of current velocity with supplementary data of wind velocity. The emphasis is on the methods of observation and the procedures used...
A large-scale west coast shelf experiment called SuperCODE
was conducted off Oregon and California between February 1981
and April 1984. Current and temperature measurements were made
from subsurface arrays off Coos Bay (43°N), Crescent City
(42°N), Eureka (41°N), Half Moon Bay (37.5°N) and Purisima
Point (34.70), between February 1981 and...
Several current meter moorings were deployed over the continental margin of Peru along 5° and 10°S to study the Peru current system. The observation period from November 1981 to March 1985 covered the occurrence of El Nino 1982-83. This report presents the six-hourly low-passed data sets of each mooring. Progressive...
Three deep-sea subsurface moorings, each equipped with five current meters at depths from 150m below the surface to 200m above the bottom, were deployed off Northern California from September 1984 to July 1985 as part of the OPTOMA program. The triad of moorings, centered near 38.5°N, 125°W, had mutual separations...
As part of the Peru Currents study, CTD observations were made off the
coasts of Peru and Ecuador between 3°N and 17°S from the R/V Wecoma,
February-March 1983 and March-April 1985, and from the R/V Endeavor,
November-December 1983 and April-May 1984. Repeated CTD sections were
occupied within 300 km of...
As part of the SuperCODE project, three hydrographic cruises were conducted
off Oregon and California in July 1983, and January to February 1984,
and April 1984. CTD observations were made near Coos Bay at 43°13'N during 12
July 1983 and 31 January 1984, and off Newport at 44°39'N on 11-12...
As part of the SuperCODE and CODE projects, two hydrographic cruises were conducted off Oregon and California in January and April 1984. CTD sections across the continental shelf and slope were made near Coos Bay at 43°13'N, off Crescent City at 41°54%, off Eureka at 40°51%, along the Arena and...
CTD observations of temperature and salinity were made off Oregon and California between 34° N and 44° N from the R/V Wecoma, 5 Feb. - 17 Feb. 1981. The stations were from 2-360 km off shore, in water depths ranging from 30 to 4,300 meters. The maximum sampling depth at...
