Equatorward jets and poleward undercurrents along the eastern boundary of the mid-latitude north Pacific

Creator:: Pierce, Stephen D.
Abstract:: We sharpen our view of an eastern boundary current region during the upwelling season through the analysis of several data sets. We focus on the mesoscale flow field off of northern California, observed during the Coastal Transition Zone (CTZ) experiment of 1988. First, we estimate tidal currents in the region...

Acoustic doppler current profiler observations during the Coastal Ocean Advances in Shelf Transport (COAST) Survey I : R/V Wecoma cruise W0105c, 23 May to 13 June 2001

Creator:: Pierce, Stephen D. and Barth, John A.
Abstract:: We present velocity observations from a shipboard acoustic Doppler current profiler (ADCP) on R/V Wecoma during cruise W0105c (23 May to 13 June 2001). The cruise was a component (Survey I) of the Coastal Ocean Advances in Shelf Transport (COAST) experiment. The ADCP was an RD Instruments hull-mounted 153.6-kHz narrowband...

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...

Dynamics of the Coastal Transition Zone Jet 1. Linear stability analysis

Creator:: Pierce, Stephen D., Allen, John S., and Walstad, Leonard J.
Abstract:: The linear stability of a coastal transition zone (CTZ) jet is analyzed using a six-layer quasi-geostrophic model with observed basic state velocity profiles. The velocity profiles are obtained from objectively analyzed hydrographic and acoustic doppler data from the 1987 CTZ pilot experiment. Along-jet perturbation wave-lengths of 260-265 km are found...

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...
