Connectivity and larval dispersal along the Oregon coast estimated by numerical simulations

Creator:: Kim, Sangil and Barth, John A.
Abstract:: Connectivity and larval dispersal is explored off the Oregon coast during the summer upwelling season of 2001 using numerical ocean circulation simulations. The study region, with strong wind-driven currents and variable topography, is modeled using the Regional Ocean Modeling System (ROMS) forced by the Coupled Ocean Atmosphere Mesoscale Prediction System....

Temporal variability of near-bottom dissolved oxygen during upwelling off central Oregon

Creator:: Adams, Katherine A., Barth, John A., and Chan, Francis
Abstract:: In the productive central-Oregon coastal upwelling environment, wind-driven upwelling, tides, and topographic effects vary across the shelf, setting the stage for varied biogeochemical responses to physical drivers. Current, temperature, salinity, and dissolved oxygen (DO) measurements from three moorings deployed during the upwelling seasons of 2009–2011 off the central-Oregon coast are...

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....

Evaluating tradeoffs among ecosystem services to inform marine spatial planning

Creator:: Lester, Sarah E., Costello, Christopher, Halpern, Benjamin S., Gaines, Steven D., White, Crow, and Barth, John A.
Abstract:: A central challenge for natural resource management is developing rigorous yet practical approaches for balancing the costs and benefits of diverse human uses of ecosystems. Economic theory has a long history of evaluating tradeoffs in returns from different assets to identify optimal investment strategies. There has been recent progress applying...

The front on the Northern Flank of Georges Bank in spring : 2. Cross-frontal fluxes and mixing

Creator:: Ullman, David S., Dale, Andrew C., Hebert, Dave, and Barth, John A.
Abstract:: Hydrographic observations made with an undulating vehicle carrying a CTD and concurrent shipboard ADCP velocity observations over a 12‐day period are combined to investigate vertical mixing and cross‐frontal fluxes on the Northern Flank of Georges Bank. The CTD density time series is analyzed to detect the presence of vertical overturns,...

Injection of carbon from the shelf to offshore beneath the euphoic zone in the California Current

Creator:: Barth, John A., Cowles, Timothy J., Kosro, P. Michael, 1951-, Shearman, R. Kipp, Huyer, Adriana, 1945-, and Smith, Robert L. (Robert Lloyd), 1935-
Abstract:: High concentrations of chlorophyll are found in the California Current System over 300 km offshore, far from the productive coastal upwelling region, and between 150 and 250 m, well below the depth to which photosynthetically active solar radiation penetrates. This exceptionally deep chlorophyll feature is formed near the coast and...

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...

Seasonal dynamics of the near-surface alongshore flow off central Chile

Creator:: Aguirre, Catalina, Pizarro, Oscar, Strub, Paul T., Garreaud, Rene, and Barth, John A.
Abstract:: The seasonal cycle of the near-surface circulation off central Chile was analyzed using satellite altimetry and an oceanic model. To evaluate the role of the wind stress curl on the circulation we performed two identical simulations except for the wind-forcing: the "control run" used long-term monthly mean wind stress and...

Coastal ocean response to summer upwelling favorable winds in a region of alongshore bottom topography variations off Oregon

Creator:: Castelao, Renato M. and Barth, John A.
Abstract:: Repeated mesoscale surveys of waters over the shelf and slope off Oregon were conducted during spring and summer of 2001 to study the spatial structure of the velocity and hydrographic fields. The ocean response to wind forcing is compared between a region of relatively simple topography with alongshore uniformity and...

Northern Monterey Bay upwelling shadow front : observations of a coastally and surface-trapped bouyant plume

Creator:: Woodson, C. B., Washburn, L., Barth, John A., Hoover, D. J., Kirinicich, A. R., McManus, M. A., Ryan, J. P., and Tyburczy, J.
Abstract:: During the upwelling season in central California, northwesterly winds along the coast produce a strong upwelling jet that originates at Point Año Nuevo and flows southward across the mouth of Monterey Bay. A convergent front with a mean temperature change of 3.77 ± 0.29°C develops between the warm interior waters...
