The focus of this dissertation is on the description and dynamical interpretation of the tidal band current fluctuations over the continental shelf off northern California. The focus of this dissertation is on the description and dynamical interpretation of the tidal band current fluctuations over the continental shelf off northern California.

The term "tidal band" is used here to denote fluctuations with periods from about one-half to one day, including all the major diurnal and semidiurnal tidal constituents.

Leslie K. Rosenfeld, Baroclinic semidiurnal tidal currents over the continental shelf off northern California, Journal of Geophysical Research: Oceans, /JCiC12p, 95, Cited by: A long‐term moored array was maintained over the northern California continental shelf from April to April as part of the Coastal Ocean Dynamics Experiment to determine the seasonal differences in the current and water temperature by: Currents at several depths were monitored on the upper slope, on the midslope and over an adjacent deep‐sea basin off northern California for nearly simultaneous periods from 4 to 14 months.

In Cited by: Leslie K. Rosenfeld, Baroclinic semidiurnal tidal currents over the continental shelf off northern California, Journal of Geophysical Research: Oceans, /JCiC12p, 95. Maximum cross-isobath tidal current is found at northern shelf locations (for instance, about 32 cm s −1 off Mumbai) than those in south (about 10 cm s −1 off Bhatkal, at 13°N).

This could be due to the amplification of semidiurnal tidal currents from south to north of the shelf due to an increase in shelf widths towards north. A characterization of the sea level variability at tidal and sub-tidal frequencies at the northern shore of the Brazilian Northeast shelf for the period – is presented.

The sea level data used was obtained from the Permanent Geodetic Tide Network from the Brazilian Institute of Geography and Statistics for the Fortaleza gauge station. A series of intermittent interval wave events were observed at a single site in m of water on the northern California continental shelf during the Coastal Ocean Dynamics Experiment Simult.

Surface tidal circulation over the continental shelf of Duck, North Carolina, was explored using surface current observations measured by a high-frequency (HF) radar.

The Ocean Surface Current Radar (OSCR) was deployed at the U.S. Army Corps of Engineers (USACE) Field Research Facility (FRF) in Duck, North Carolina, during October and measured surface current at min intervals at. Continental shelf baroclinic instability.

Currents over the Continental Shelf tend to flow southeastward and slightly offshore in summer, causing nutrient-rich cool waters to upwell onto the shelf. Shelf currents flow mostly northwestward in winter. Tidal currents are strong over the shelf.

Low and High Tide Predictions for California with Sunrise, Sunset, Moonrise, Moonset, and Moon Phase. How to use: Pick the site in California for the tides. Then scroll to the bottom of this page.

Select (highlight) the month, start date, and total days. Press the Get Tides button. Such variability has also been considered either noise (Cartwright and Amin, ), a manifestation of frictional interaction (Godin and Gutierrez, ), or the interaction between tidal currents and a shelf current varying with the seasons (Kang et al., ).

The first two explanations require an extensive data set to be tested, so they. California tide tables & charts. California Tide Tables & Charts: Popular: Fitzgerald Marine Reserve Tide Pools.

Variability in stratification associated with upwelling can affect not only the propagation of the internal tide on the shelf, but also the barotropic-to-baroclinic energy conversion on the continental slope, in this case changing the classification of the slope from nearly critical to supercritical such that less barotropic tidal energy is.

Coastal sea level time series were obtained for 10 tide gauge locations ().Sea level data were adjusted by adding equivalent sea level pressure ( m mbar −1 atmospheric pressure) measured at nearby stations in order to estimate subsurface time series were low-pass filtered using a cosine Lanczos filter with a half-power point of 46 h and decimated every 6 h.

The focus of this dissertation is on the description and dynamical interpretation of the tidal band current fluctuations over the continental shelf off northern California.

The term "tidal band. Diurnal period wind stress and current fluctuations measured over the continental shelf off northern California during the Coastal Ocean Dynamics Experiment in the summers of and are.

The tidal range is the horizontal distance the water line moves between ebb tide and flood tide. vertical difference in sea surface elevation between high tide and low tide. time lapse between high tide and low tide. minimum depth of the water at a specific location during low tide.

It is unknown how this variability affects tidal current variability on the New England shelf. [3] Barotropic and baroclinic tides are important because they affect a variety of shelf processes including bottom stress and frictional dissipation, property mixing in the bottom boundary layer, and sediment resuspension.

Also. In northern California, an anticyclonic eddy off the coast was found to transport plumes of suspended sediments from the continental shelf into the deep ocean (Washburn et al., ); and in the.

Description Tidal based current variability over the Northern California continental shelf EPUB

A 6-month deployment of instrumentation from April to October in 90 m water depth near the outer edge of the mid-shelf mud belt in southern Monterey Bay, California, reveals the importance regional upwelling on water column density structure, potentially accounting for the majority of the variability in internal tidal energy flux across the shelf.

This suggestion was based on the small-scale spatial variability of the diurnal sea-surface amplitudes (large wave number structures) confined along the Portuguese northern shelf.

The same variability was shown in the current velocity magnitude (Fig. 14) and current. This book represents an outgrowth of an interdisciplinary session held at the Seventh International Estuarine Research Federation Conference held at Virginia Beach, Virginia, OCLober At that mee.

Title: Tidal Band Current Variability over the Northern California Continental Shelf. Honors. Member Phi Beta Kappa and Sigma Xi. Previous Positions. Oceanographer, Naval Oceanographic Office, Assistant Staff Oceanographer, Chesapeake Bay Institute, The Johns Hopkins University,   The California Current is the eastern part of the great anticyclonic North Pacific gyre.

This surface current (0– m deep) transports water from the subpolar region, which is high in dissolved oxygen (5–7 ml l −1) and low in temperature (15–20 °C) and salinity (–) (Reid et al.,Lynn and Simpson, ).The typical velocity of the California Current is ∼25 cm s −1.

Tidal currents generally dominate the flow field in many submarine canyons, and the internal tides may be an order of magnitude more energetic than the barotropic tidal currents (Kunze et al., ).The internal tidal current-associated water–mass displacements may have major effects on the sediment transport, as suggested by McPhee-Shaw et al.
