A Coupled Bio-Optical and Mixed Layer Model for the Equatorial Pacific
<p>A one dimensional coupled bio-optical and mixed layer model is developed and applied to problems involving the role of phytoplankton-induced turbidity (PIT) on the vertical structure and heating of the upper ocean in the Equatorial Pacific Ocean. The bio-optical and mixed layer model for …

Single-column and mixed-layer model analysis of subtropical stratocumulus response mechanisms relevant to climate change
… parameterized cloud processes in global climate models (GCMs). Improving our understanding of the role stratocumulus clouds play in response to climate change requires both a better understanding of the underlying physical mechanisms that govern stratocumulus clouds, and also better representing …

Simulation of annual cycles of phytoplankton, zooplankton and nutrients using a mixed layer model coupled with a biological model
In oceanography, the mixed layer refers to the near surface part of the water column where physical and biological variables are distributed quasi homogeneously. Its depth depends on conditions at the air-sea interface (heat and freshwater fluxes, wind stress) and on the characteristics of the flow …

Winter mixed-layer development in the central Irminger Sea : the effect of strong, intermittent wind events
… of the Greenland tip jet on the wintertime mixed-layer of the southwest Irminger Sea is investigated using in-situ moored profiler data and a variety of atmospheric data sets. The mixed-layer was observed to reach 400 m in the spring of 2003, and 300 m in the spring of 2004. Both of these …

Oceanic mixed layer entrainment zone dynamics
The Naval Postgraduate School mixed layer model is augmented to include an entrainment zone with finite thickness. The role of entrainment shear production of turbulent kinetic energy is investigated by comparing model results that include the new entrainment zone with observations at Ocean Weather …

Wind-driven circulation on a shallow, stratified shelf
… 1988-89 is carried out through a combination of modeling, scale estimates, and data analysis. We develop a prognostic one-dimensional mixed layer model which is coupled to a thermodynamic ice model. Our model contains a representation of the lowest order boundary layer dynamics and adjustable …

Wind, sea ice, inertial oscillations and upper ocean mixing in Marguerite Bay, Western Antarctic Peninsula : observations and modeling
… the Upper Circumpolar Deep Water to the surface mixed layer indicate almost no contribution from double diffusive convection. A one-dimensional vertical mixed layer model adapted for investigation of mixing beneath an ice-covered ocean indicates that the initial wind event, rather than subsequent …

Arabian Sea mixed layer deepening during the monsoon : observations and dynamics
The unusual twice-yearly cycle of mixed layer deepening and cooling driven by the monsoon is analyzed using a recently collected (1994-95) dataset of concurrent local air-sea fluxes and upper ocean dynamics from the Arabian Sea. The winter northeast monsoon has moderate wind forcing and a strongly …

Evolution of the Irminger Current anticyclones in the Labrador Sea from hydrographic data
… data from 1990-2004 and a 1-dimensional mixed layer model. There were 50 eddies found in the hydrographic data record, 48 of which were identified as anticyclones. Vertical structure of the eddies was investigated, leading to the categorization of all the anticyclones into three classes: …

The impact of submesoscales on the stratification dynamics in the Southern Ocean
… the role of submesoscales on the evolution of mixed layer depth and upper ocean stratification in the open-ocean Subantarctic Ocean. First, we present autonomous ocean glider measurements from spring to late-summer to show that transient increases in stratification within the mixed layer during …

Near-inertial and thermal upper ocean response to atmospheric forcing in the North Atlantic Ocean
Observational and modeling techniques are employed to investigate the thermal and inertial upper ocean response to wind and buoyancy forcing in the North Atlantic Ocean. First, the seasonal kinetic energy variability of near-inertial motions observed with a moored profiler is described. Observed …
