Temperature, salinity, and dissolved oxygen concentration
measured in an estuary were analyzed to determine if the effects of
coastal upwelling could be observed and used to effectively monitor
the degree of upwelling.
Hydrographic data collected weekly at a point four miles from
the entrance of Yaquina Bay (Buoy 15) were...
Coastal upwelling helps set the physical context for marine ecosystems, and upwelling zones are among the most productive regions of the global ocean. Unlike earlier models, two state‐of‐the‐art climate models exhibit little change during the next century in the magnitude and seasonality of coastal upwelling, but climate models are still...
Hydrographic observations were made over the continental shelf and slope off Oregon during the 1973 Coastal Upwelling Experiment (CUE-II) from three ships: R/V OCEANOGRAPHER, R/V THOMAS G. THOMPSON, and R/V YAQUINA. This report contains the observations made on four YAQUINA cruises between June and August 1973 (Table I). Observations were...
Air–sea coupling during coastal upwelling was examined through idealized three-dimensional numerical simulations with a coupled atmosphere–ocean mesoscale model. Geometry, topography, and initial and
boundary conditions were chosen to be representative of summertime coastal conditions off the Oregon coast. Over the 72-h simulations, sea surface temperatures were reduced several degrees near...
Abstract: Coastal upwelling zones may be at enhanced risk from ocean acidification as upwelling brings low aragonite saturation state (Ω[subscript Ar]) waters to the surface that are further suppressed by anthropogenic CO₂. Ω[subscript Ar] was calculated with pH, pCO₂, and salinity-derived alkalinity time series data from autonomous pH and pCO₂...
Observations of wind, currents, sea level and hydrography
obtained during the 1972 Coastal Upwelling Experiment (CUE-I) are
described. Only phenomena with periods longer than a day are considered.
One section describes the changes observed during a period
of variable winds in early July 1972. Another describes a ribbon of
relatively...
Ammonium uptake and regeneration rates were measured in time course experiments with 15N as a tracer. Both ammonium uptake and regeneration rates measured over 12 to 18 h remained essentially constant. However, as the length of the incubations increased the amount of usable data decreased dramatically due to substrate depletion...
