The impact of submesoscales on the stratification dynamics in the Southern Ocean
Submesoscale dynamics O(1-10 km, hours to days) are considered to strongly affect the stratification of the upper ocean. In the Southern Ocean, studies of submesoscale dynamics are biased to regions preconditioned for strong frontal activity and topographical influence. This dissertation considers …

Modeling ocean transport and its biogeochemical impacts at global, regional, and sub-meso scales
… emissions technology. We find that local ocean dynamics are crucial for determining optimal alkalinity addition locations that maximize carbon removal, while minimizing adverse ecological impacts. Among the best locations identified are coastal upwelling systems, which are also regions of high …

Submesoscale turbulence in the upper ocean
Submesoscale flows, current systems 1–100 km in horizontal extent, are increasingly coming into focus as an important component of upper-ocean dynamics. A range of processes have been proposed to energize submesoscale flows, but which process dominates in reality must be determined observationally. …

Identification and characterisation of submesoscale activity over the continental shelf in the Bay of Biscay
… as fundamental processes in the generation of submesoscale features (a few kilometres to tens of kilometres spatial scale and temporal variability of the order of a day). Consequently, the present study (part of DYMETER project, IFREMER) aims at exploring the development mechanisms of these …

The evolution of ocean fronts in the presence of mixed layer turbulence
Fronts, or regions with large horizontal density gradients, are common and important features of the upper ocean. On sufficiently large scales, the hydrostatic pressure gradient associated with the horizontal density gradient is often nearly balanced by a geostrophic (or thermal wind) …

Submesoscale Biophysical Interactions on the Gulf Stream: Eddies, Fronts, and New Observational Methods
… are linkages between physics and biology at the submesoscale (horizontally O(0.1-10) km, vertically O(.1) km, temporally O(1) day) that could help explain broad scale properties in ocean biology. Persistent fronts of western boundary currents like the Gulf Stream are hotspots for submesoscale …

Vertical fluxes in the upper ocean
Oceanic fronts at the mesoscale and submesoscale are associated with enhanced vertical motion, which strengthens their role in global biogeochemical cycling as hotspots of primary production and subduction of carbon from the surface to the interior. Using process study models, theory, and field …

High-order Discontinuous Galerkin Methods and Deep Reinforcement Learning with Application to Multiscale Ocean Modeling
… concomitant increases in computing power, and submesoscale resolutions where nonhydrostatic effects are important are progressively becoming approachable in ocean modeling. However, few realistic ocean circulation models presently have nonhydrostatic capability, and those that do overwhelmingly …
