As part of an experiment to study wind-driven coastal circulation, 17 hydrographic
surveys of the middle to inner shelf region off the coast of Newport, OR (44.65°N, from
roughly the 90 m isobath to the 10 m isobath) were performed during Summer 1999
with a small, towed, undulating vehicle. The...
Drifters released offshore of Oregon during predominantly downwelling favorable alongshore winds during three different deployments (October 1994, January 1998, and September 1998) display similar behavior: after being advected around in the offshore eddy field, they move onshore to a particular isobath and are advected poleward alongshore, without coming ashore. Numerical...
During Spring and Summer 1999, as part of the Oregon State University National Oceanographic Partnership Program (OSU-NOPP) field program, 20 successful hydrographic surveys were undertaken on the Oregon mid- to inner shelf, all near Yaquina Bay. These consisted of 17 cross-shelf sections along the Newport Hydrographic line ( extending approximately...
During fall/winter off the Oregon coast, oceanographic surveys are relatively scarce because of rough
weather conditions. This challenge has been overcome by the use of autonomous underwater gliders deployed
along the Newport hydrographic line (NH-Line) nearly continuously since 2006. The discharge from the
coastal rivers between northern California and the...
From mid-May to August 2011, extreme runoff in the Columbia River ranged from 14,000 to over 17,000 m³/s, more than two standard deviations above the mean for this period. The extreme runoff was the direct result of both melting of anomalously high snowpack and rainfall associated with the 2010–2011 La Niña....
