A Nonlinear Baroclinic Wave-Mean Oscillation with Multiple Normal Mode Instabilities

Creator:: Samelson, R. M. and Wolfe, C. L.
Abstract:: An unstable, nonlinear baroclinic wave-mean oscillation is found in a strongly supercritical quasigeostrophic f-plane numerical channel model with 3840 Fourier components. The growth of linear disturbances to this time-periodic oscillation is analyzed by computing time-dependent normal modes (Floquet vectors). Two different Newton–Picard methods are used to compute the unstable solution,...

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...

Scales of variability of bio-optical properties as observed from near-surface drifters

Creator:: Abbott, Mark R., Brink, Kenneth H., Booth, C. R., Blasco, Dolors, Swenson, Mark S., Davis, Curtiss O., and Codispoti, L. A.
Abstract:: A drifter equipped with bio-optical sensors and an automated water sampler was deployed in the California Current as part of the coastal transition zone program to study the biological, chemical, and physical dynamics of the meandering filaments. During deployments in 1987 and 1988, measurements were made of fluorescence, downwelling irradiance,...

Current meter data from the Samoan Passage experiment : world ocean circulation experiment current meter array PCM-11 : September 1992-February 1994

Creator:: Pillsbury, R. Dale, Rudnick, Daniel L., Bottero, J. M., Pittock, G., Root, D. C., Simpkins, J., III., and Still, R. E.
Abstract:: The Samoan Passage experiment was designed to determine the northward transport of abyssal water through the Samoan Passage (l0°S, 170°W). This topographic constriction forms the major connection for deep (>4000 m) interbasin flow between hemispheres in the Pacific (Figure 1). This report presents current meter data from the six subsurface...

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...

Climate Sensitivity of the Community Climate System Model, Version 4

Creator:: Bitz, C. M., Shell, K. M., Gent, P. R., Bailey, D. A., Danabasoglu, G., Armour, K. C., Holland, M. M., and Kiehl, J. T.
Abstract:: Equilibrium climate sensitivity of the Community Climate System Model, version 4 (CCSM4) is 3.20 degrees C for 1 degrees horizontal resolution in each component. This is about a half degree Celsius higher than in the previous version (CCSM3). The transient climate sensitivity of CCSM4 at 1 degrees resolution is 1.72...

Minor and trace element chemistry of Lake Baikal, its tributaries, and surrounding hot springs

Creator:: Falkner, Kelly, Church, M., Measures, Chris I., LeBaron, G., Thouron, D., Jeandel, C., Stordal, M. C., Gill, G. A., Mortlock, R., Froelich, P., and Chan, L.-H.
Abstract:: A Russian–American fieldwork effort on Lake Baikal, its tributaries, and surrounding hot springs was undertaken in June–July 1991. Here we report on aspects of major ion (Ca2+, Mg2+, Na+, K+, Alk, Cl–, SO42–) and several minor and trace element (Li isotopes, Sr isotopes, Ba, Al, V, Cr, Ni, Cu, Ge,...

A novel method for determination of aragonite saturation state on the continental shelf of central Oregon using multi-parameter relationships with hydrographic data

Creator:: Juranek, L. W., Freely, R. A., Peterson, W. T., Alin, S. R., Hales, Burke, Lee, K., Sabine, C. L., and Peterson, J.
Abstract:: We developed a multiple linear regression model to robustly determine aragonite saturation state (Ωarag) from observations of temperature and oxygen (R² = 0.987, RMS error 0.053), using data collected in the Pacific Northwest region in late May 2007. The seasonal evolution of Ωarag near central Oregon was evaluated by applying...

The Inverse Ocean Modeling System. Part I: Implementation

Creator:: Bennett, A. F., Chua, B. S., Pflaum, B. L., Erwig, M., Fu, Z., Loft, R. D., and Muccino, J. C.
Abstract:: The Inverse Ocean Modeling (IOM) system constructs and runs weak-constraint, four-dimensional variational data assimilation (W4DVAR) for any dynamical model and any observing array. The dynamics and the observing algorithms may be nonlinear but must be functionally smooth. The user need only provide the model and the observing algorithms, together with...
