Secondary circulation associated with a shelfbreak front

Creator:: Barth, John A., Bogucki, Darek, Pierce, Stephen D., and Kosro, P. Michael, 1951-
Abstract:: Evidence for secondary circulation associated with a shelfbreak front is obtained from a high‐resolution, cross‐shelf section of hydrographic, optical and velocity fields. Convergence in the bottom boundary layer on the inshore side of the front and subsequent upwelling into the interior is evident by a mid‐water region of suspended bottom...

Improving Acoustic Doppler Current Profiler Accuracy with Wide-Area Differential GPS and Adaptive Smoothing of Ship Velocity

Creator:: Pierce, Stephen D., Barth, John A., and Smith, Robert L.
Abstract:: Accurate ship velocity is important for determining absolute currents from acoustic Doppler current profiler (ADCP) measurements. In this paper, the authors describe the application of two methods to improve the quality of ship velocity estimates. The first uses wide-area differential global positioning system (WADGPS) navigation to improve ship positioning. During...

Declining Oxygen in the Northeast Pacific

Creator:: Pierce, Stephen D., Barth, John A., Shearman, R. Kipp, and Erofeev, Anatoli Y.
Abstract:: Climate models predict a decrease in oceanic dissolved oxygen and a thickening of the oxygen minimum zone, associated with global warming. Comprehensive observational analyses of oxygen decline are challenging, given generally sparse historical data. The Newport hydrographic (NH) line off central Oregon is one of the few locations in the...

Anomalously warm July 2005 in the northern California Current : historical context and the significance of cumulative wind stress

Creator:: Pierce, Stephen D., Barth, John A., Thomas, Rebecca E., and Fleischer, Guy W.
Abstract:: In the northern California Current, the onset of the 2005 upwelling season was five weeks later than usual, and well established upwelling with a cold surface signature did not occur until about seven weeks after this. As part of the joint US-Canada Pacific hake survey, from 14–16 July 2005 we...

Mesoscale physical and bio-optical structure of the Antarctic Polar Front near 170°W during austral spring

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...
