Observations and a Model of the Mean Circulation over the Middle Atlantic Bight Continental Shelf
Journal of Physical Oceanography - Tập 38 Số 6 - Trang 1203-1221 - 2008
Steven J. Lentz
Abstract Analyses of current time series longer than 200 days from 33 sites over the Middle Atlantic Bight continental shelf reveal a consistent mean circulation pattern. The mean depth-averaged flow is equatorward, alongshelf, and increases with increasing water depth from 3 cm s−1 at the 15-m isobath to 10 cm s−1 at the 100-m isobath. The mean cros...... hiện toàn bộ
Seasonal Variations in the Circulation over the Middle Atlantic Bight Continental Shelf
Journal of Physical Oceanography - Tập 38 Số 7 - Trang 1486-1500 - 2008
Steven J. Lentz
Abstract Fits of an annual harmonic to depth-average along-shelf current time series longer than 200 days from 27 sites over the Middle Atlantic Bight (MAB) continental shelf have amplitudes of a few centimeters per second. These seasonal variations are forced by seasonal variations in the wind stress and the cross-shelf density gradient. ...... hiện toàn bộ
Observations of Cross-Shelf Flow Driven by Cross-Shelf Winds on the Inner Continental Shelf
Journal of Physical Oceanography - Tập 38 Số 11 - Trang 2358-2378 - 2008
Melanie R. Fewings, Steven J. Lentz, Janet Fredericks
Abstract Six-yr-long time series of winds, waves, and water velocity from a cabled coastal observatory in 12 m of water reveal the separate dependence of the cross-shelf velocity profile on cross-shelf and along-shelf winds, waves, and tides. During small waves, cross-shelf wind is the dominant mechanism driving the cross-shelf circulation after tide...... hiện toàn bộ
Interplay of Wind Forcing and Buoyant Discharge off Montauk Point: Seasonal Changes to Velocity Structure and a Coastal Front
Journal of Physical Oceanography - Tập 35 Số 6 - Trang 1068-1085 - 2005
Daniel L. Codiga
Abstract Seasonal-mean currents in fall, winter, and spring on the bathymetrically complex continental shelf 15–65 m deep off Montauk Point, outside Block Island Sound, are analyzed using moored profiling current-meter records from a 2.5-yr period. A sharp boundary, or coastal front, occurs where strong, shallow, generally southwestward flow that wea...... hiện toàn bộ
Wave-Driven Inner-Shelf Motions on the Oregon Coast*
Journal of Physical Oceanography - Tập 39 Số 11 - Trang 2942-2956 - 2009
Anthony Kirincich, Steven J. Lentz, John A. Barth
Abstract Recent work by S. Lentz et al. documents offshore transport in the inner shelf due to a wave-driven return flow associated with the Hasselmann wave stress (the Stokes–Coriolis force). This analysis is extended using observations from the central Oregon coast to identify the wave-driven return flow present and quantify the potential bias of w...... hiện toàn bộ
Observations and a Model of Undertow over the Inner Continental Shelf
Journal of Physical Oceanography - Tập 38 Số 11 - Trang 2341-2357 - 2008
Steven J. Lentz, Melanie R. Fewings, Peter A. Howd, Janet Fredericks, Kent Hathaway
Abstract Onshore volume transport (Stokes drift) due to surface gravity waves propagating toward the beach can result in a compensating Eulerian offshore flow in the surf zone referred to as undertow. Observed offshore flows indicate that wave-driven undertow extends well offshore of the surf zone, over the inner shelves of Martha’s Vineyard, Massach...... hiện toàn bộ
Cyclonic Eddies in the Gulf of Mexico: Observations by Underwater Gliders and Simulations by Numerical Model
Journal of Physical Oceanography - Tập 45 Số 1 - Trang 313-326 - 2015
Daniel L. Rudnick, Ganesh Gopalakrishnan, Bruce D. Cornuelle
AbstractCirculation in the Gulf of Mexico (GoM) is dominated by the Loop Current (LC) and by Loop Current eddies (LCEs) that form at irregular multimonth intervals by separation from the LC. Comparatively small cyclonic eddies (CEs) are thought to have a controlling influence on the LCE, including its separation from the LC. Because the CEs are so dynamic and short...... hiện toàn bộ
Improved Oceanic Cool-Skin Corrections Using a Refined Solar Penetration Model
Journal of Physical Oceanography - Tập 35 Số 11 - Trang 1986-1996 - 2005
Gary A. Wick, J. Carter Ohlmann, C. W. Fairall, Andrew T. Jessup
Abstract The oceanic near-surface temperature profile must be accurately characterized to enable precise determination of air–sea heat exchange and satellite retrievals of sea surface temperature. An improved solar transmission parameterization is integrated into existing models for the oceanic warm layer and cool skin within the Tropical Ocean and G...... hiện toàn bộ

Oceanic Fluxes in the South Atlantic
Journal of Physical Oceanography - Tập 35 Số 1 - Trang 109-122 - 2005
Elaine L. McDonagh, Brian King
Abstract A box inverse of the World Ocean Circulation Experiment A10 (30°S) and A11 (nominally 45°S) sections in the South Atlantic Ocean was undertaken. The authors find a heat flux across A10 of 0.22 ± 0.08 PW, consistent with previous studies, and a heat flux of 0.43 ± 0.08 PW across A11. The A11 heat flux is lower than some previous analyses of t...... hiện toàn bộ
