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...

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...

Genome-Wide Characterization of Light-Regulated Genes in Neurospora crassa

Creator:: Wu, Cheng, Yang, Fei, Smith, Kristina M., Peterson, Matthew, Dekhang, Rigzin, Zhang, Ying, Zucker, Jeremy, Bredeweg, Erin L., Mallappa, Chandrashekara, Zhou, Xiaoying, Lyubetskaya, Anna, Townsend, Jeffrey P., Galagan, James E., Freitag, Michael, Dunlap, Jay C., Bell-Pedersen, Deborah, and Sachs, Matthew S.
Abstract:: The filamentous fungus Neurospora crassa responds to light in complex ways. To thoroughly study the transcriptional response of this organism to light, RNA-seq was used to analyze capped and polyadenylated mRNA prepared from mycelium grown for 24 hr in the dark and then exposed to light for 0 (control) 15,...

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...

Anomalous ichthyoplankton distributions and concentrations in the northern California Current during the 2010 El Niño and La Niña events

Creator:: Auth, Toby D., Brodeur, Richard D., and Peterson, Jay O.
Abstract:: In late spring of 2010, the northern California Current (NCC) experienced a transition from El Niño to La Niña conditions resulting in anomalous distributions and concentrations within the ichthyoplankton community. We analyzed larval fish data collected during the four months before and after this transition and compared them to data...

A comparative analysis of coastal and shelf-slope copepod communities in the northern California Current system: Synchronized response to large-scale forcing?

Creator:: Bi, Hongsheng, Peterson, William T., Peterson, Jay O., and Fisher, Jennifer L.
Abstract:: The synchrony between coastal and shelf-slope copepod communities was investigated in the northern California Current (NCC) system, a strong upwelling zone, using time series of zooplankton sampled from a nearshore station (9 km offshore, water depth 62 m) and a shelf-slope station (46 km offshore, water depth 297 m). Long-term...

Anomalous Near-Surface Low-Salinity Pulses off the Central Oregon Coast

Creator:: Mazzini, Piero L. F., Risien, Craig M., Barth, John A., Pierce, Stephen D., Erofeev, Anatoli, Dever, Edward P., Kosro, P. Michael, Levine, Murray D., Shearman, R. Kipp, and Vardaro, Michael F.
Abstract:: 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....

Multiple trophic levels fueled by recirculation in the Columbia River plume

Creator:: Kudela, Raphael M., Horner-Devine, Alexander R., Banas, Neil S., Hickey, Barbara M., Peterson, Tawnya D., McCabe, Ryan M., Lessard, Evelyn J., Frame, Elizabeth, Bruland, Kenneth W., Jay, David A., Peterson, Jay O., Peterson, William T., Kosro, P. Michael, Palacios, Sherry L., Lohan, Maeve C., and Dever, Edward P.
Abstract:: Large rivers represent gateways for the transport of terrigenous and anthropogenic material to the coastal ocean. Here we document a ∼700 km2 recirculation or bulge associated with the Columbia River plume that retains recently discharged river water sufficiently to create a regional bioreactor. Fueled by a fluvial nitrate source, this...
