Tidal mixing over a slope was explored using moored time series observations on Kaena Ridge extending northwest from Oahu, Hawaii, during the Survey component of the Hawaii Ocean Mixing Experiment (HOME). A mooring was instrumented to sample the velocity and density field of the lower 500 m of the water...
In the heat of summer in the Rogue Valley, yellow starthistle (Centaurea solstitialis) raises heads of brilliant yellow flowers rigidly defended by sharp spines. Although bees reap double benefits of nectar and pollen during a season when most native plants no longer are flowering, this nonnative weed is a threat...
These thistles are native to Europe and the Middle East.
Some are not true thistles; for example, purple/Iberian and
yellow starthistle actually are knapweeds. All of these plants, however,
share a spiny, thorny, invasive nature and long-lasting, hard seed. These traits make people who use or manage land for recreation,...
This report documents the observations of velocity, temperature and conductivity made from two moorings deployed in the Kauai Channel on the ridge extending NW from Oahu, Hawaii. The moorings were deployed in November 2000 for two months as part of the Hawaii Ocean Mixing Experiment (HOME) Survey Program.
This report documents oceanographic and meteorological measurements made from instruments deployed on four moorings over the continental shelf west of Oregon, from spring through
summer, 1999. These moorings were a component of an observational and numerical modeling program to study the response of the coastal ocean to wind forcing.

Closely spaced vertical profiles through the bottom boundary layer over a sloping continental shelf during relaxation from coastal upwelling reveal structure that is consistent with convectively driven mixing. Parcels of fluid were observed adjacent to the bottom that were warm (by several millikelvin) relative to fluid immediately above. On average,...
‘Sacajawea’ (OSU 540.130) was developed and evaluated at Oregon State University, Corvallis, Oregon, and was released in February 2006. Compared to ‘Barcelona,’ ‘Sacajawea’ is a slightly smaller tree but has a higher yield efficiency, a higher percent kernel, fewer kernel defects, and smaller nuts. Nuts mature and fall free of...
Near the bottom, the velocity profile in the bottom boundary layer over the continental
shelf exhibits a characteristic law-of-the-wall that is consistent with local estimates of
friction velocity from near-bottom turbulence measurements. Farther from the bottom, the
velocity profile exhibits a deviation from the law-of-the-wall. Here the velocity gradient
continues...
"'Yamhill' (OSU 542.102) was developed and evaluated by the hazelnut breeding program at Oregon State University, Corvallis, Oregon, and was released in January 2008. Trees of 'Yamhill' are completely resistant to eastern filbert blight (EFB) caused by Anisogramma anomala (Peck) E. Müller. Compared to 'Barcelona', trees of 'Yamhill' are smaller...
