Creator:: Barth, John A.
Abstract:: The stability of a coastal jet and front is investigated using the primitive equations applied to a continuously stratified flow in geostrophic balance. A linear stability analysis successfully explains the growth of two modes of instability with distinctly different horizontal scales. A long-wavelength mode (fastest-growing wavelength of 0(100 km)) is...

Creator:: Castelao, Renato M., Mavor, Timothy P., Barth, John A., and Breaker, Laurence C.
Abstract:: Sea surface temperature (SST) fronts are determined for the 2001–2004 time period from Geostationary Operational Environmental Satellites (GOES) data in the California Current System (CCS). The probability of detecting a SST front at an individual pixel location in the CCS is presented as a bi-monthly climatology. Fronts clearly indicate the...

Creator:: Warner, John C., Geyer, W. Rockwell, and Lerczak, James A.
Abstract:: Numerical simulations of the Hudson River estuary using a terrain-following, three-dimensional model (Regional Ocean Modeling System (ROMS)) are compared with an extensive set of time series and spatially resolved measurements over a 43 day period with large variations in tidal forcing and river discharge. The model is particularly effective at...

Abstract:: As the Mendocino Triple Junction migrates northward along the California margin it is widely presumed to leave a "slab-free" or "asthenospheric" window in its wake. A 250-km-long south-north seismic refraction-reflection profile crossing the transition from transform to subduction regimes allows us to compare and contrast crust and upper mantle of...

Creator:: Dale, Andrew C., Barth, John A., Levine, Murray D., and Austin, J. A.
Abstract:: Observations, from the Oregon continental shelf, describe the slumping of a coastal upwelling front in response to a reversal of winds from upwelling-to downwelling-favorable. Initially, the front outcropped in a surface mixed layer of depth 10–20 m with a pronounced cross-shelf density gradient. Following wind reversal, both the unbalanced cross-shelf...

Creator:: Dale, Andrew C., Ullman, David S., Barth, John A., and Hebert, Dave
Abstract:: During March–April 1999, 2 weeks of undulating CTD and shipboard acoustic Doppler current profiler surveys revealed the variability of the intense internal tide on the northern edge of Georges Bank. The nature of the internal tide was modulated by episodic surface intrusions of cool, fresh Scotian Shelf Water (SSW), stratifying...

Creator:: Braunmiller, Jochen and Nábělek, John
Abstract:: The Blanco Transform Fault Zone (BTFZ) forms the ~350 km long Pacific–Juan de Fuca plate boundary between the Gorda and Juan de Fuca ridges. Nearby broadband seismic networks provide a unique framework for a detailed, long-term seismotectonic study of an entire oceanic transform fault (OTF) system. We use regional waveforms...

Creator:: Kim, Sangil and Barth, John A.
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....

Abstract:: The Explorer region offshore western Canada is a tectonically complex area surrounded by the Pacific, North America, and Juan de Fuca plates. Existing tectonic models for the region differ fundamentally. Proposed plate configurations range from multiple independent plate fragments to an Explorer plate now fused to North America along the...

Creator:: Gan, Jianping and Allen, John S.
Abstract:: A two-part modeling study of the wind-forced flow on the continental shelf off northern California in the region (37°–40°N) of the Coastal Ocean Dynamics Experiment (CODE) is pursued. This paper involves a process-oriented study with idealized wind stress forcing. Gan and Allen [2002] involves forcing with observed winds and heat...
