Lagrangian study of the Southern Ocean circulation
The Southern Ocean is an important region for the sequestration of heat, carbon dioxide and other tracers. The Southern Ocean circulation is typically described in a circumpolarly averaged sense as a Meridional Overturning Circulation (MOC), but the detailed 3-D pathways that make up this …

Arctic Ocean circulation in an idealized numerical model
The mid-to-deep Arctic Ocean is generally characterized by a cyclonic circulation, contained along shelves and ridges. Here we analyze the general Arctic circulation using an idealized numerical model consisting of a circular basin with two channels acting as inflow and outflow. We analyze the …

Kinematics and energetics of the mesoscale mid-ocean circulation : MODE
… observations, obtained as part of the Mid-Ocean Dynamics Experiment (MODE), are analyzed to study the kinematics and energetics of mesoscale eddies in the ocean. The temporal variability of the low frequency motions is characterized by three regimes: very low frequencies with periods …

Ocean circulation and dynamics on the west Antarctic Peninsula continental shelf
… cruises conducted by the United States Southern Ocean GLOBEC program on the western Antarctic Peninsula continental shelf are used to characterize the ocean circulation and its connection to fresh water and heat fluxes on the shelf. Mean velocities on the shelf are of the order of 5 cm/s or less. …

The Effect of Arctic River Hydrological Cycles on Arctic Ocean Circulation
<p>Understanding Arctic Ocean circulation may be critical to fully understanding the global oceanic salt and heat cycles and their response to climate variability. This thesis examines how one important aspect of Arctic Ocean circulation, the effect of freshwater inflow, may contribute to the …

Modeling Non-Rotational Ocean Circulation and Heat Distribution in Icy Moons
Subsurface oceans beneath the ice shells of icy moons like Europa and Enceladus are considered promising environments for extraterrestrial life. Their long-term habitability depends on internal heating and efficient vertical heat transport to maintain liquid water beneath the surface. This study …

The impact of wave-modified wind stress in an ocean circulation model
… flux parametrization is introduced in the ocean circulation model HYCOM. The physical process driving this parametrization is the growing and dissipation of the surface wave field. Two numerical experiments are conducted for the South Atlantic: one with the new wave effect included and a …

On the role of topography and of boundary forcing in the ocean circulation
… of strong jets in the interior of the model ocean. According to the structure of the topography these internal jets can occur in both vertically homeogenous and baroclinic oceans. If the topographic slope changes sign, then one kind of jets is observed both in stratified and in homogeneous …

Atlantic Ocean circulation at the Last Glacial Maximum : inferences from data and models
This thesis focuses on ocean circulation and atmospheric forcing in the Atlantic Ocean at the Last Glacial Maximum (LGM, 18-21 thousand years before present). Relative to the pre-industrial climate, LGM atmospheric CO2 concentrations were about 90 ppm lower, ice sheets were much more extensive, and …

Inferring ocean circulation during the Last Glacial Maximum and last deglaciation using data and models
… This thesis combines global models and paleoceanographic observations to constrain the ocean’s role in storing and transporting heat, salt, and other tracers during this time, with implications for understanding how the modern ocean works and how it might change in the future. • By combining …

Ocean circulation and carbon cycle dynamics in the Pacific Southern Ocean during Late Pleistocene interglacials
The Southern Ocean is a key component of the global ocean overturning circulation, enabling water mass exchange between ocean basins, driving Antarctic Bottom Water and Antarctic Intermediate Water formation and providing the major return path of Circumpolar Deep Water (CDW) to the ocean surface. …
