Wind-driven inner-shelf circulation off central Oregon during summer

Creator:: Kirincich, Anthony R., Barth, John A., Grantham, Brian A., Menge, Bruce A., and Lubchenco, Jane
Abstract:: Velocity measurements from 17 deployments of moored acoustic Doppler current profilers obtained during four summer upwelling seasons are used to describe the crossshelf divergence of Ekman transport in the inner shelf off Oregon. For each deployment the measured surface and bottom cross-shelf transports were compared with estimates of the theoretical...

Semidiurnal Baroclinic Tides on the Central Oregon Inner Shelf

Creator:: Suanda, Sutara H. and Barth, John A.
Abstract:: Semidiurnal velocity and density oscillations are examined over the mid- and inner continental shelf near Heceta Bank on the Oregon coast. Measurements from two long-term observation networks with sites on and off the submarine bank reveal that both baroclinic velocities and displacements are dominated by the first mode, with larger...

Alongshelf Variability of Inner-Shelf Circulation along the Central Oregon Coast during Summer

Creator:: Kirincich, Anthony R. and Barth, John A.
Abstract:: The spatial and temporal variability of inner-shelf circulation along the central Oregon coast during the 2004 upwelling season is described using a 70-km-long array of moorings along the 15-m isobath. Circulation at three stations located onshore of a submarine bank differed from that of a station north of the bank,...

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....

Wave-Driven Inner-Shelf Motions on the Oregon Coast*

Creator:: Kirincich, Anthony R., Lentz, Steven J., and Barth, John A.
Abstract:: Recent work by S. Lentz et al. documents offshore transport in the inner shelf due to a wave-driven return flow associated with the Hasselmann wave stress (the Stokes–Coriolis force). This analysis is extended using observations from the central Oregon coast to identify the wave-driven return flow present and quantify the...

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...

SeaSoar observations during the Coastal Ocean Advances in Shelf Transport (COAST) mesoscale survey II : R/V Wecoma cruise from 6 to 26 August 2001

Creator:: O'Malley, Robert T., Barth, John A., and Erofeev, Anatoli Y.
Abstract:: As part of the Coastal Ocean Processes (CoOP) project Coastal Ocean Advances in Shelf Transport (COAST), this was the second of two cruises in 2001 to study cross-shelf transport processes in a wind-driven coastal ocean. The project includes field experiments off the Oregon coast and coordinated ocean circulation/ecosystem and atmospheric...

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...

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...
