Creator:: Jay, Jeremy Barth
Abstract:: A sequence of volcanic, volcaniclastic, and epiclastic deposits from Oligocene to Recent age are exposed in the region from Lake Simtustus to Madras in central Oregon. The epiclastic sediments of the Oligocene John Day Formation are unconformably overlain by two flows of the middle Miocene Columbia River Basalt Group. The...

Variation in the position of the upwelling front on the Oregon shelf

Creator:: Austin, Jay A. and Barth, John A.
Abstract:: 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...

Drifter Behavior on the Oregon–Washington Shelf during Downwelling-Favorable Winds

Creator:: Austin, Jay A. and Barth, John A.
Abstract:: 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...

Small-boat hydrographic surveys of the Oregon mid- to inner shelf : May-September 1999 : a component of the Prediction of Wind-Driven Coastal Circulation Project

Creator:: Austin, Jay Alan, Barth, John A., Pierce, Stephen D., and Oregon State University. College of Oceanic and Atmospheric Sciences
Abstract:: 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...

Buoyancy-Driven Coastal Currents off Oregon during Fall and Winter

Creator:: Mazzini, Piero L. F., Barth, John A., Shearman, R. Kipp, and Erofeev, A.
Abstract:: 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...

Are large macroalgal blooms necessarily bad? nutrient impacts on seagrass in upwelling-influenced estuaries

Creator:: Hessing-Lewis, Margot L., Hacker, Sally D., Menge, Bruce A., McConville, Sea-oh, and Henderson, Jeremy
Abstract:: Knowledge of nutrient pathways and their resulting ecological interactions can alleviate numerous environmental problems associated with nutrient increases in both natural and managed systems. Although not unique, coastal systems are particularly prone to complex ecological interactions resulting from nutrient inputs from both the land and sea. Nutrient inputs to coastal...

Seasonal and interannual variation in the extent of hypoxia in the northern California Current from 1998–2012

Creator:: Peterson, Jay O., Morgan, Cheryl A., Peterson, William T., and Di Lorenzo, Emanuele
Abstract:: This study addresses the occurrence, severity, and extent of hypoxia over the continental shelf of the northern California Current (40–48.5°N latitude) from 1998 to 2012. Clear seasonal trends exist in the timing and duration of hypoxia. The highest bottom-water dissolved oxygen concentrations occurred from November to March, and levels below...
