An Estimate of Tidal Energy Lost to Turbulence at the Hawaiian Ridge

Creator:: Klymak, Jody M., Moum, James N., Nash, Jonathan D., Kunze, Eric, Girton, James B., Carter, Glenn S., Lee, Craig M., Sanford, Thomas B., and Gregg, Michael C.
Abstract:: An integrated analysis of turbulence observations from four unique instrument platforms obtained over the Hawaiian Ridge leads to an assessment of the vertical, cross-ridge, and along-ridge structure of turbulence dissipation rate and diffusivity. The diffusivity near the seafloor was, on average, 15 times that in the midwater column. At 1000-m...

Energetics of M₂ Barotropic-to-Baroclinic Tidal Conversion at the Hawaiian Islands

Creator:: Carter, G. S., Merrifield, M. A., Becker, J. M., Katsumata, K., Gregg, M. C., Luther, D. S., Levine, M. D., Boyd, Timothy John, 1958-2013, and Firing, Y. L.
Abstract:: A high-resolution primitive equation model simulation is used to form an energy budget for the principal semidiurnal tide (M₂) over a region of the Hawaiian Ridge from Niihau to Maui. This region includes the Kaena Ridge, one of the three main internal tide generation sites along the Hawaiian Ridge and...

Energy Flux and Dissipation in Luzon Strait: Two Tales of Two Ridges

Creator:: Alford, Matthew H., MacKinnon, Jennifer A., Nash, Jonathan D., Simmons, Harper, Pickering, Andy, Klymak, Jody M., Pinkel, Robert, Sun, Oliver, Rainville, Luc, Musgrave, Ruth, Beitzel, Tamara, Fu, Ke-Hsien, and Lu, Chung-Wei
Abstract:: Internal tide generation, propagation, and dissipation are investigated in Luzon Strait, a system of two quasi-parallel ridges situated between Taiwan and the Philippines. Two profiling moorings deployed for about 20 days and a set of nineteen 36-h lowered ADCP-CTD time series stations allowed separate measurement of diurnal and semidiurnal internal...

Global Patterns of Diapycnal Mixing from Measurements of the Turbulent Dissipation Rate

Creator:: Waterhouse, Amy F., MacKinnon, Jennifer A., Nash, Jonathan D., Alford, Matthew H., Kunze, Eric, Simmons, Harper L., Polzin, Kurt L., St. Laurent, Louis C., Sun, Oliver M., Pinkel, Robert, Talley, Lynne D., Whalen, Caitlin B., Huussen, Tycho N., Carter, Glenn S., Fer, Ilker, Waterman, Stephanie, Naveira Garabato, Alberto C., Sanford, Thomas B., and Lee, Craig M.
Abstract:: The authors present inferences of diapycnal diffusivity from a compilation of over 5200 microstructure profiles. As microstructure observations are sparse, these are supplemented with indirect measurements of mixing obtained from (i) Thorpe-scale overturns from moored profilers, a finescale parameterization applied to (ii) shipboard observations of upper-ocean shear, (iii) strain as...

A Global Climatology of Surface Wind and Wind Stress Fields from Eight Years of QuikSCAT Scatterometer Data

Creator:: Risien, Craig M. and Chelton, Dudley B.
Abstract:: Global seasonal cycles of the wind and wind stress fields estimated from the 8-yr record (September 1999–August 2007) of wind measurements by the NASA Quick Scatterometer (QuikSCAT) are presented. While this atlas, referred to here as the Scatterometer Climatology of Ocean Winds (SCOW), consists of 12 variables, the focus here...

Finite-Amplitude Evolution of Instabilities Associated with the Coastal Upwelling Front

Creator:: Durski, Scott M. and Allen, J. S.
Abstract:: A primitive equation model is used to study the finite-amplitude evolution of instabilities associated with the coastal upwelling front. Simulations of increasing complexity are examined that represent idealizations of summer conditions off the Oregon coast, including cases with steady and with time-variable wind in a domain with alongshore-uniform bathymetry and...

Internal Bores and Breaking Internal Tides on the Oregon Continental Slope

Creator:: Martini, Kim I., Alford, Matthew H., Kunze, Eric, Kelly, Samuel M., and Nash, Jonathan D.
Abstract:: Observations of breaking internal tides on the Oregon continental slope during a 40-day deployment of 5 moorings along 43°12'N are presented. Remotely generated internal tides shoal onto the slope, steepen, break, and form turbulent bores that propagate upslope independently of the internal tide. A high-resolution snapshot of a single bore...

Turbulence Decay and Restratification in the Equatorial Ocean Surface Layer following Nighttime Convection

Creator:: Caldwell, D. R., Lien, R-C., Moum, J. N., and Gregg, M. C.
Abstract:: Although the process of restratification of the ocean surface layer at the equator following nighttime convection is similar in many ways to the process at midlatitudes, there are important differences. A composite day calculated from 15 days of consistent conditions at 140°W on the equator was compared with midlatitude observations...

An Observational Estimate of Volume and Freshwater Flux Leaving the Arctic Ocean through Nares Strait

Creator:: Munchow, Andreas, Melling, Humfrey, and Falkner, Kelly K.
Abstract:: The Arctic Ocean is an important link in the global hydrological cycle, storing freshwater and releasing it to the North Atlantic Ocean in a variable fashion as pack ice and freshened seawater. An unknown fraction of this return flow passes through Nares Strait between northern Canada and Greenland. Surveys of...
