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...
Two physical oceanography cruises on the R/V Endeavor were conducted by the co-PIs Jack Barth and Mike Kosro as part of the ONR-sponsored Coastal Mixing and Optics (CMO) Accelerated Research Initiative. The objective was to rapidly survey a region around 40.5N, 70.5W where a set of moorings and a stationary...
We present velocity observations from a shipborne acoustic Doppler current profiler (ADCP) on RIV Wecoma during cruise W9408A, August 23 to September 2, 1994. The ADCP processing procedures are described in detail. This cruise was part of the Coastal Jet Separation project, funded by the National Science Foundation, to study...
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...
We present velocity observations from a shipboard acoustic Doppler current profiler (ADCP) on RJV Revelle during cruises R9710 (20 October to 23 November 1997) and R9801 (9 January to 7 February 1998). The cruises were conducted as part of the Southern Ocean JGOFS (Joint Global Ocean Flux) Antarctic Polar Frontal...
We present velocity observations from a shipboard acoustic doppler current profiler (ADCP) on RN Wecoma during cruise W9508b, 17-27 August 1995. Results from the short half-day cruise W9508c on 31 August 1995 are also shown. The ADCP processing procedures for W9508b are described in detail. This cruise was part of...
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...
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...
We present velocity observations from a shipboard acoustic Doppler current profiler (ADCP) on RN Endeavor during cruises E9608 (14 August to 1 September 1996) and E9704 (25 April to 15 May 1997). The cruises were conducted as part of the Office of Naval Research Coastal Mixing and Optics Accelerated Research...
During Spring and Summer 1999, as part of the Oregon State University National Oceanographic Partnership Program (OSU-NOPP) field program, 20 successful hydrographic surveys were undertaken on the Oregon mid- to inner shelf, all near Yaquina Bay. These consisted of 17 cross-shelf sections along the Newport Hydrographic line ( extending approximately...
We present velocity observations from a shipboard acoustic Doppler current profiler (ADCP) on
R/V Wecoma during cruise W0301b (19 January - 3 February 2003). The cruise was a component
(Survey III) of the Coastal Ocean Advances in Shelf Transport (COAST) experiment. The
ADCP was an RD Instruments hull-mounted 153-kHz narrowband...
We present velocity observations from a shipboard acoustic Doppler current profiler (ADCP) on
R/V Wecoma during cruise W0108a (6-25 August 2001). The cruise was a component (Survey
II) of the Coastal Ocean Advances in Shelf Transport (COAST) experiment. The ADCP was an
RD Instruments hull-mounted 153-kHz narrowband unit. Data were...
We present velocity observations from a shipboard acoustic Doppler current profiler (ADCP) on RIV Revelle during cruises R9711 (30 November 1997 to 3 January 1998) and R9802 (13 February 1998 to 19 March 1998). The cruises were conducted as part of the Southern Ocean JGOFS (Joint Global Ocean Flux) Antarctic...
