Creator:: Barth, John A., Pierce, S. D., and Castelao, R. M.
Abstract:: During summer 2001, high-resolution hydrographic, velocity, and bio-optical surveys were conducted over Heceta Bank off central Oregon. North of the bank, upwelling over simple bottom topography exhibited a classic response with a midshelf, baroclinic coastal jet and upwelled isopycnals. The coastal upwelling jet follows the bank topography as it widens...

Creator:: Barth, John A., Hebert, Dave, Dale, Andrew C., and Ullman, David S.
Abstract:: By mapping the three-dimensional density field while simultaneously tracking a subsurface, isopycnal float, direct observations of upwelling along a shelfbreak front were made on the southern flank of Georges Bank. The thermohaline and bio-optical fields were mapped using a towed undulating vehicle, and horizontal velocity was measured with a shipboard...

Abstract:: Horizontal current measurements from an array of moored acoustic Doppler profilers are assimilated sequentially into a model of coastal wind-driven circulation off Oregon during the upwelling season of May–August 2001. Model results are compared against independent moored and ship survey data to document a positive effect of velocity data assimilation...

Creator:: Barth, John A., Cowles, Timothy J., and Pierce, Stephen D.
Abstract:: As part of the U.S. Joint Global Ocean Flux Study Southern Ocean program, high-resolution surveys of the Antarctic Polar Front near 170øW were conducted during October-November 1997 with a towed undulating system equipped with conductivity-temperature-depth and bio-optical sensors. Transects along 170°W and two successive mapping surveys revealed zonal bands with...

Creator:: Kirincich, Anthony R. and Barth, John A.
Abstract:: The event-scale variability of across-shelf transport was investigated using observations made in 15 m of water on the central Oregon inner shelf. In a study area with intermittently upwelling-favorable winds and significant density stratification, hydrographic and velocity observations show rapid across-shelf movement of water masses over event time scales of...

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...

Creator:: Barth, John A. and Wheeler, Patricia A.
Abstract:: The Coastal Ocean Advances in Shelf Transport (COAST) program conducted an interdisciplinary study of coastal upwelling off central Oregon during summer 2001. Two intensive field efforts during May–June and August 2001 were coordinated with ocean circulation, ecosystem, and atmospheric modeling of the region. A primary goal was to contrast the...

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....
