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...

Mixing of chlorophyll from the Middle Atlantic Bight cold pool into the Gulf Stream at Cape Hatteras in July 1993

Creator:: Wood, A. Michelle, Sherry, Nelson D., and Huyer, Adriana, 1945-
Abstract:: In July 1993 we collected hydrographic data and information on chlorophyll distribution on the continental shelf north of Cape Hatteras and across the shelf break at Cape Hatteras. The data show that a warm, transparent mixed layer lies over much colder, euphotic, chlorophyll-rich bottom water on the shelf. This layer...

Observed Interaction between Low and High Frequency Motions off the Coasts of Peru and California

Creator:: Kundu, Pijusi K., Beardsley, Robert C., and Huyer, Adriana
Abstract:: Datasets taken near the coasts of Peru and California have been analyzed to explore the evidence of a correlation between the high frequency (period < 10.8 hour) and low frequency (period > 4 day) motions. A large part of the high frequency current is consistent with internal wave dynamics. They...

The Leeuwin Current off Western Australia, 1986–1987

Creator:: Smith, Robert L., Huyer, Adriana, Godfrey, J. Stuart, and Church, John A.
Abstract:: The Leeuwin Current in the Indian Ocean off Western Australia differs from the other major eastern boundary currents, e.g., California Current, since it flows rapidly poleward against the prevailing equatorward wind. The first large-scale study of the Leeuwin Current was conducted between North West Cape (22°S) and the south-western corner...

Abstract:: The dynamics of the coastal transition zone off Northern California during late May and early June 1987 art examined through assimilation modeling studies. A regional baroclinic quasi-geostrophic model is driven by the data through initial and boundary conditions. These initial and boundary conditions are specified by objective analysis of hydrographic...

Abstract:: Conductivity‐temperature‐depth surveys during 1988 encountered strong baroclinic jets that were evident in acoustic Doppler current profiler and hydrographic data. During June and July 1988 a filament with high surface nitrate, high chlorophyll, abundant populations of neritic centric diatoms, and higher rates of primary production was evident perpendicular to the coast...
