My Research Statement as a Word Cloud
The concentration of chemotactic bacteria in a turbulent flow. See movie page for a full description.
An internal gravity wave in the process of breaking from a direct numerical simulation visualized with two partially transparent isopycnal surfaces.
From the same simulation of an internal wave, later in the breaking phase. Here density is colored with the least dense layers made transparent.
From the same simulation of an internal wave, here the white contour is an isopycnal surface, and color indicates regions with high enstrophy.
Eddies generated through baroclinic instability. Color indicates the vertical relative vorticity (warm colors are positive and cold colors are negative.) See the moves page for a full description of the simulation.
From a direct numerical simulation of a turbulent oceanic bottom Ekman layer. The flow outside the boundary layer is stratified and in geostrophic balance. Near the bottom the flow (visualized with streamribbons) turns to the left. The bottom isosurface is drawn at a constant streamwise velocity and shows turbulent wall streaks.
Chlorophyll concentration inferred from NASA's MODIS satellite from the Mozambique channel, shown on a log scale. A large mesoscale eddies is clearly visible in the center of the image with small submesoscale eddies along its rim.
Phytoplankton concentration from a numerical simulation of turbulent convection, seen from below. Plumes carrying phytoplankton cells to the bottom of the mixed layer can be seen. More details and a top view of this simulation are on the movies page.
A large eddy simulation of symmetric instability at a front forced by surface cooling. See movie page for more details.
From the same simulation of symmetric instability. Here a passive dye was released near the surface and is visualized some time later. The dye can be seen extending down from the surface along an isopycnal surface, while Kelvin-Helmholtz billows are clearly visible.
