An empirical statistical model is developed that relates the non-tidal motion of the ocean surface currents off the Oregon coast to forecasts of the coastal winds. The empirical statistical model is then used to produce predictions of the surface currents that are evaluated for their agreement with measured currents. Measurements...
The Northern California Current (NCC) ecosystem exhibits extreme seasonal, interannual and interdecadal shifts in the abiotic environment and shifts in primary and higher production. This variability is also apparent in the spatial structure of the ecosystem with nearshore-shelf waters (<150 m isobath) being highly productive and having a different community...
Inner-shelf circulation and mechanisms of across-shelf transport of water masses were examined using seven years of observations collected by the Partnership for Interdisciplinary Studies of Coastal Oceans (PISCO) program, a long-term monitoring effort along the central Oregon coast. Since 1998, moored velocity and hydrographic measurements have been obtained during the...
This is the first data report of a program designed to study physical
processes in Oregon shelf waters by means of moored instrument arrays.
Various statistics and plots of smoothed data are presented for time
series of current velocity and of temperature. Data were collected in
July, August, September, and...
The area near Point Arguello has long been recognized as a location of strong
upwelling. A tongue of biologically active waters was observed in the earliest studies of
this region (Sverdrup and Allen, 1939). More recently, satellite estimates of chlorophyll by
the Coastal Zone Color Scanner (CZCS) on Nimbus-7 have...
A summary of one phase of a direct observational program conducted
in the coastal region off Oregon is presented. The measurements
were made primarily on the continental shelf during most of the coastal
upwelling season (May and June 1967; April through September 1968).
The principal measurements were time series of...
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...
Observations from an instrument array moored over the continental
shelf off Oregon from 31 July to 21 September 1969 are presented. Temperature,
current and wind observations were obtained every 20 minutes.
First order statistics, histograms, progressive vector diagrams and time
series plots are presented. Supplementary wind observations at Newport
are...
