Creator:: Kosro, P. Michael, 1951-
Abstract:: A time series of hourly surface current maps in the shelf waters off Newport, Oregon, was made during April–September 2001 using five SeaSonde HF current mappers, during Coastal Advances in Shelf Transport (COAST). The surface currents responded rapidly to the changing winds, in repeated patterns that were strongly affected by...

Creator:: Kosro, P. Michael, 1951-
Abstract:: For 74 days during the spring and summer upwelling seasons of 1981 and 1982, in conjunction with the Coastal Ocean Dynamics Experiment, profiles of upper ocean currents were collected in the waters over the shelf and slope off northern California using a shipboard Doppler acoustic log. These measurements provide detailed...

Creator:: Kosro, P. Michael, 1951-
Abstract:: Moored current measurements from the Oregon shelf during 1998–2003 are used to estimate time series of anomalous alongshore currents and pseudo-displacements, after accounting for the mean and seasonal cycle. From early January through mid-June, 2002, currents at 10 m were anomalously strong toward the south by an average 12 cm/s,...

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...

Creator:: Erofeeva, Svetlana Y., Egbert, Gary D., and Kosro, P. Michael, 1951-
Abstract:: Measurements of tidal currents on the central Oregon shelf are available from several sources, including recent high frequency (HF) coastal radar and Acoustic Doppler Profiler (ADP) deployments, and historical current moorings. In this paper we use a generalized inverse (GI) approach to compare these data to, and then assimilate them...

Creator:: Pierce, Stephen D., Barth, John A., and Kosro, P. Michael, 1951-
Abstract:: 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...

Abstract:: In 2005, the onset of spring conditions in the physics of the coastal ocean (lowered sea level, spin-up of vertically-sheared equatorward coastal jet) came about 50 days later than average off Newport Oregon, on May 24. There was a further delay of 50 days before the subsurface upwelled water penetrated...

Creator:: Oke, Peter R., Allen, John S., Miller, Robert N., Egbert, Gary D., and Kosro, P. Michael, 1951-
Abstract:: A data assimilation system (DAS) of the wind‐driven, mesoscale shelf circulation off the Oregon coast is developed. The DAS assimilates low‐pass filtered surface velocity measurements, obtained from land‐based high‐frequency coastal radar arrays, into a primitive equation coastal ocean model using a sequential optimal interpolation scheme. Inhomogeneous and anisotropic estimates of...
