An average of approximately 200,000 pounds of bay clams were harvested annually in Oregon for the years 1943-49, inclusive. The commercial harvest of bay clams is composed of the gaper, cockle, and softshell clams. The recreational, or noncommercial, harvest of bay clams is composed mainly of the gaper, cockle, softshell,...
As part of the Coastal Ocean Processes (CoOP) project Coastal Ocean Advances in Shelf Transport (COAST), this was the second of two cruises in 2001 to study cross-shelf transport processes in a wind-driven coastal ocean. The project includes field experiments off the Oregon coast and coordinated ocean circulation/ecosystem and atmospheric...
An analytical model of subtropical mode water is presented, based on ventilated thermocline theory and on numerical solutions of a planetary geostrophic basin model. In ventilated thermocline theory, the western pool is a region bounded on the east by subsurface streamlines that outcrop at the western edge of the interior,...
As part of the U. S. GLOBEC NorthEast Pacific Program we made repeated seasonal hydrographic surveys in the northern California Current system (Figure 1) between July 1997 and September 2003. These surveys included early spring sampling along a pair of hydrographic sections, one north (at 44.6ºN) and one south (at...
As part of the GLOBEC Northeast Pacific Program, a Long Term Observation Program (LTOP) of repeated hydrographic observations along lines off Oregon began in September 1997 (Fleischbein et al, 1999). Of these lines, NH, off Newport, had been sampled frequently during the decade from 1961 to 1970, and another, FM,...
PURPOSE: To determine physical, plankton and nutrient/chemical conditions over the continental margin for climate change studies in NE Pacific. In particular, to make CTD and CTD/rosette and net tow stations along the Newport Hydro line, to make continuous bio-acoustic observations between the 50-500m. isobath, and to make continuous observations of...
PURPOSE: To determine physical, plankton and nutrient/chemical conditions over the continental margin for climate change studies in NE Pacific. In particular, to make CTD and CTD/rosette and net tow stations along 5 lines (off Newport, Heceta Head, Coos Bay, the Rogue River and Crescent City, OR, to deploy drifters at...
This report contains the data gathered at Ocean Station "P" in late June and early July of 1971 on the "SUBARCTIC-A" cruise of R/V YAQUINA. The data include: 1) temperature, salinity, and oxygen profiles; 2) estimates of zooplankton displacement volumes at different depths; and 3) estimates of the numerical density...
CTD observations were made in the CODE region between Pt. Arena(39° N) and Pt. Reyes(38°N), during 1-4 August 1981. The observations included two repeated sections along the Central Line, one section along the North Line, and one section in the region of the Pt. Ross Line rur during previous cruises....
CTD observations were made in the CODE region between Pt. Arena (39°N) and Pt. Reyes (38°N) during 20-24 April 1982. The observations were made along seven sections: Irish Gulch, Arena, North, Code-North, Code Central, Code-2 Central and Ross Lines, and along the fifty fathom contour. Maximum sampling depth was 1000...
CTD observations were made in the Code region near Pt. Arena on the northern California coast at 39° N during 14-27 July 1982. The observations in the Code region included three repeated sections along the Central Line, two mesoscale surveys of the shelf/slope region, and an alongshore section over the...
Temperature observations are presented from 4 Aanderaa thermistor chains suspended from a free-floating surface buoy during October-November 1983 near 33.5° N, 126.5° W as part of the Mixed Layer Dynamics Experiment (MILDEX). Each chain contained 11 sensors; the upper two were 30 min length, the lower two were 100 m...
CTD observations were made over the continental shelf and upper continental slope from the coast to approximately 60 km off central California between latitudes 34°N and 37.5°N. The measurements were made by Raytheon Service Company as part of the Central California Coastal Circulation Study sponsored by the Minerals Management Service....
Temperature, salinity, sigma-t and dissipation profiles from the Rapid Sampling Vertical Profiler for six transects as part of the Coastal Transition zone pilot experiment, June 1987.
Hydrographic and optical measurements were made in situ in the Congo River and the Angola Basin during May 1978. These measurements were made by members of the optical oceanography group at Oregon State University in cooperation with scientists from the Netherlands Institute for Sea Research. The data taken by the...
We present velocity observations from a shipboard acoustic doppler current profiler (ADCP) on RN Wecoma during cruise W9508b, 17-27 August 1995. Results from the short half-day cruise W9508c on 31 August 1995 are also shown. The ADCP processing procedures for W9508b are described in detail. This cruise was part of...
We present velocity observations from a shipboard acoustic Doppler current profiler (ADCP) on RJV Revelle during cruises R9710 (20 October to 23 November 1997) and R9801 (9 January to 7 February 1998). The cruises were conducted as part of the Southern Ocean JGOFS (Joint Global Ocean Flux) Antarctic Polar Frontal...
We present velocity observations from a shipboard acoustic Doppler current profiler (ADCP) on R/V Wecoma during cruise W0105c (23 May to 13 June 2001). The cruise was a component (Survey I) of the Coastal Ocean Advances in Shelf Transport (COAST) experiment. The ADCP was an RD Instruments hull-mounted 153.6-kHz narrowband...
