A numerical study of melt ponds

Creator:: Skyllingstad, Eric D. and Paulson, Clayton A.
Abstract:: High-resolution turbulence simulations are used to examine the importance of melt pond geometry in setting pond growth rates and albedo. Modeling the circulation of water in melt ponds using large-eddy simulation shows that both convective and windforced conditions generate well-mixed ponds, suggesting that stratification is not a significant factor in...

A numerical study of the Magellan Plume

Creator:: Palma, Elbio D. and Matano, Ricardo P.
Abstract:: In this modeling study we investigate the dynamical mechanisms controlling the spreading of the Magellan Plume, which is a low-salinity tongue that extends along the Patagonian Shelf. Our results indicate that the overall characteristics of the plume (width, depth, spreading rate, etc.) are primarily influenced by tidal forcing, which manifests...

K. P., Zaneveld, R., and Zappa, C. J.
Abstract:: Optical variability occurs in the near-surface and upper ocean on very short time and space scales (e.g., milliseconds and millimeters and less) as well as greater scales. This variability is caused by solar, meteorological, and other physical forcing as well as biological and chemical processes that affect optical properties and...

Mesoscale and large-eddy simulation model studies of the Martian atmosphere in support of Phoenix

Creator:: Tyler, Daniel, Barnes, Jeffrey R., and Skyllingstad, Eric D.
Abstract:: In late May of 2008, the NASA/JPL Phoenix spacecraft will touch down near its targeted landing site on Mars (68.2°N, 126.6°W). Entry, descent, and landing (EDL) occurs in the late afternoon (~1630 hours local solar time (LST)) during late northern spring (Ls ~ 78°). Using a mesoscale and a large-eddy...

A study of the optical characteristics of the suspended particles in the benthic nepheloid layer of the Scotian Rise

Creator:: Spinrad, Richard W., Zaneveld, J. Ronald, and Kitchen, James C.
Abstract:: Light transmission profiles have been used to study the optical properties of the suspended particles which are characteristic of the area of the Scotian Rise in the North Atlantic Ocean. This area is typified by very strong bottom currents and a highly variable bedform morphology. A good correlation (r =...

Variational assimilation of satellite observations in a coastal ocean model off Oregon

Creator:: Kurapov, A. L., Foley, D., Strub, P. T., Egbert, G. D., and Allen, J. S.
Abstract:: Satellite along-track sea surface height (SSH) and multisatellite sea surface temperature (SST) maps are assimilated in a coastal ocean circulation model off Oregon. The study period is June–October 2005, featuring intensive separation of the coastal upwelling jets in the eddy-dominated coastal transition zone (CTZ). The data assimilation (DA) system combines...

Modeling study of turbulent mixing over the continential shelf : comparison of turbulent closure schemes

Creator:: Wijesekera, H. W., Allen, John S., and Newberger, P. A.
Abstract:: The sensitivity of model-produced time-dependent wind-driven circulation on the continental shelf to the turbulent closure scheme employed is studied with a twodimensional approximation (variations across-shelf and in depth) using the Princeton Ocean Model. The level 2.5 Mellor-Yamada closure (MY), k-ε closure, and K-Profile Parameterization schemes are used to evaluate the...

Turbulence beneath sea ice and leads: a coupled sea ice/large-eddy simulation study

Creator:: Skyllingstad, Eric D. and Denbo, Donald W.
Abstract:: The importance of leads, sea ice motion, and frazil ice on the wintertime ocean Boundary layer was examined by using a large-eddy simulation turbulence model coupled to a thermodynamic slab ice model. Coupling was achieved through exchange coefficients that accounted for the differing diffusion rates of heat and salinity. Frazil...

Eddy properties in the California Current System

Creator:: Kurian, Jaison, Colas, Francois, Capet, Xavier, McWilliams, James C., and Chelton, Dudley B.
Abstract:: Eddy detection and tracking algorithms are applied to both satellite altimetry and a high‐resolution (dx = 5 km) climatological model solution of the U.S. West Coast to study the properties of surface and undercurrent eddies in the California Current System. Eddy properties show remarkable similarity in space and time, and...

Experimental study of nearshore dynamics on a barred beach with rip channels

Creator:: Haller, Merrick C., Dalrymple, Robert A., and Svendsen, Ib A.
Abstract:: Wave and current measurements are presented from a set of laboratory experiments performed on a fixed barred beach with periodically spaced rip channels using a range of incident wave conditions. The data demonstrate that the presence of gaps in otherwise longshore uniform bars dominates the nearshore circulation system for the...
