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...
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...
Pesticides, including insecticides, acaricides, fungicides, bactericides, and herbicides are essential for maintaining healthy grape crops with reliable
yields and quality. In many instances, pesticides have become less effective as target organisms have developed resistance. The first record of resistance dates to 1897, when orchardists began having problems controlling San Jose...
Measurements of suspended sediment concentration, velocity, salinity, and turbulent
microscale shear in the near-field region of the Columbia River plume are used to investigate
the mechanisms of sediment resuspension and entrainment into the plume. An east-west
transect was occupied during spring and neap tide periods in August 2005 and May...
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...
A multidisciplinary team of scientists (Appendix 1) examined 10 of the 16 environmental benchmarks that are tracked by the Oregon Progress Board. The intent of the environmental benchmarks is to provide a fair assessment of the status and trends of Oregon's environmental health. The scientists were asked to clarify benchmark...
