The distribution of Antarctic Intermediate Water in the South
Pacific has been examined using a model of horizontal advection,
along the Sigma-t surface 27.10, with three point vertical mixing.
The core of the Antarctic Intermediate Water mass was traced
from the Antarctic Convergence northward. The charts used to
describe the...
On Oregon coastal rocky shores, filter‐feeders were relatively abundant and macrophytes were relatively scarce at Strawberry Hill, whereas opposite abundance patterns occurred at Boiler Bay. To determine whether nearshore oceanographic differences were associated with these patterns, we made shore‐based measurements of nutrient and Chl a concentrations. We used a three‐level...
During July 1970, albacore boats trolling surface jigs (jig boats) had record catches in an area off the mouth of the Columbia River. The jig fishery declined suddenly in late July and was poor throughout the remainder of the summer. No obvious oceanographic changes were correlated with these drastic changes...
Gravity observations were made with the LaCoste-Romberg underwater
gravity meter during July and August 1962 at 149 stations
in an area 10 by 40 miles (44°10' to 44°50'N latitude and 124°
07' to 124°20'W longitude) off the north-central Oregon coast
from Heceta Head to Depoe Bay. The primary purpose of...
Marine renewable energy promises to assist in the effort to reduce
carbon emissions worldwide. As with any large-scale development in the marine
environment, however, it comes with uncertainty about potential environmental
impacts, most of which have not been adequately evaluated—in part because many of
the devices have yet to be...
Oregon State University is now observing its Centennial Year. The
first hundred years has brought immense growth to the institution which
is reflected in the last decade.by the initiation and development of a
Department of Oceanography.
The rip current field resulting from the transformation of surface gravity waves over offshore submarine canyons is studied. Employing a wave transformation model and a wave-induced circulation model over observed bathymetry we find that rip current circulation cells exist with alongshore spacing of O(1OOm) even though the nearshore bathymetry displayed...
The temporal and spatial variability of crescentic sandbars is analyzed with hourly
long-term (months) video observations collected at four barred sites and are qualitatively
compared to the temporal and spatial variability predicted by hypotheses underpinning
existing approaches and models for crescentic bar formation (edge-wave template model,
linear stability analysis, and...
