Evolution of 1996-1999 La Niña and El Niño conditions off the western coast of South America: A remote sensing perspective

Creator:: Carr, Mary-Elena, Strub, P. Ted, Thomas, Andrew C., and Blanco, Jose Luis
Abstract:: We present the evolution of oceanographic conditions off the western coast of South America between 1996 and 1999, including the cold periods of 1996 and 1998–1999 and the 1997–1998 El Niño, using satellite observations of sea level, winds, sea surface temperature (SST), and chlorophyll concentration. Following a period of cold...

Potential for non-destructive astrochemistry using the ExoMars PanCam

Creator:: Storrie-Lombardi, Michael C., Muller, J.-P., Fisk, Martin R., Griffiths, A. D., and Coates, A. J.
Abstract:: We investigate the utility of adding a 365 nm ultraviolet (UV) light source to the ExoMars panoramic camera (PanCam) scheduled for launch in 2013. The modification makes it feasible to monitor rover drill cuttings for aromatic organic molecules and provide constraints on polycyclic aromatic hydrocarbons (PAH) as a function of...

Modeling upwelling circulation off the Oregon coast

Creator:: Gan, Jianping and Allen, John S.
Abstract:: Time‐dependent, three‐dimensional, upwelling circulation on the continental shelf off the Oregon coast is studied using a primitive equation numerical model. A limited area domain with a high‐resolution curvilinear grid is utilized. The response of the coastal ocean to forcing by observed wind stress and heat flux during the summer 2001...

Forcing a three-dimensional, hydrostatic, primitive-equation model for application in the surf zone : 2. application to DUCK94

Creator:: Newberger, P. A. and Allen, John S.
Abstract:: A three‐dimensional primitive‐equation model for application to the nearshore surf zone has been developed. This model, an extension of the Princeton Ocean Model (POM), predicts the wave‐averaged circulation forced by breaking waves. All of the features of the original POM are retained in the extended model so that applications can...

Assimilation of surface velocity data into a primitive equation coastal ocean model

Creator:: Oke, Peter R., Allen, John S., Miller, Robert N., Egbert, Gary D., and Kosro, P. Michael, 1951-
Abstract:: A data assimilation system (DAS) of the wind‐driven, mesoscale shelf circulation off the Oregon coast is developed. The DAS assimilates low‐pass filtered surface velocity measurements, obtained from land‐based high‐frequency coastal radar arrays, into a primitive equation coastal ocean model using a sequential optimal interpolation scheme. Inhomogeneous and anisotropic estimates of...

A modeling study of shelf circulation off northern California in the region of the Coastal Ocean Dynamics Experiment 2. Simulations and comparisons with observations

Creator:: Gan, Jianping and Allen, John S.
Abstract:: This is the second part of a modeling study of wind-forced flow on the continental shelf off northern California in the region (37°-40°N) of the Coastal Ocean Dynamics Experiment (CODE). Gan and Allen [2002] analyzed the shelf flow response to idealized wind stress forcing in a process-oriented study. The study...

Influence of the Amsterdam/St. Paul hot spot along the Southeast Indian Ridge between 77° and 88°E: Correlations of Sr, Nd, Pb, and He isotopic variations with ridge segmentation

Creator:: Nicolaysen, K. P., Frey, F. A., Mahoney, J. J., Johnson, K. T. M., and Graham, David W.
Abstract:: The submarine Amsterdam-St. Paul (ASP) Plateau, bisected by the Southeast Indian Ridge (SEIR), is a bathymetric high rising ~2 km above the surrounding seafloor that includes the islands of Amsterdam and St. Paul; this excess volcanism is attributed to a mantle hot spot. We obtained new Sr, Nd, and Pb...

Role of morphologic feedback in surf zone sandbar response

Creator:: Plant, Nathaniel G., Freilich, Michael H., and Holman, Robert A.
Abstract:: Several aspects of feedback mechanisms associated with surf zone sandbar response have been characterized using bathymetric surveys, sampled approximately monthly over a 16-year period at the Army Corps of Engineers' Field Research Facility (North Carolina). The measured bathymetry was alongshore averaged and modeled by the superposition of two Gaussian-shaped sandbars...

Numerical modeling of the global semidiurnal tide in the present day and in the last glacial maximum

Creator:: Egbert, Gary D., Ray, Richard D., and Bills, Bruce G.
Abstract:: A hydrodynamic model incorporating a self‐consistent treatment of ocean self‐attraction and loading (SAL), and a physically based parameterization of internal tide (IT) drag, is used to assess how accurately barotropic tides can be modeled without benefit of data, and to explore tidal energetics in the last glacial maximum (LGM). M2...

Tidal currents on the central Oregon shelf : models, data, and assimilation

Creator:: Erofeeva, Svetlana Y., Egbert, Gary D., and Kosro, P. Michael, 1951-
Abstract:: Measurements of tidal currents on the central Oregon shelf are available from several sources, including recent high frequency (HF) coastal radar and Acoustic Doppler Profiler (ADP) deployments, and historical current moorings. In this paper we use a generalized inverse (GI) approach to compare these data to, and then assimilate them...
