 | Freshwater discharge in narrow, surface trapped, boundary plumes is a common feature of many coastal areas and straits, especially in the high latitudes. Such plumes have typically been described with synoptic measurements or steady state theoretical models and little is know about their variability or the factors which may influence it. Here we take advantage of there years of moored data across the outflow from Hudson Strait, which transport a ... |

| The recent decreasing trend of sea ice cover in the Arctic region and its projected future reduction has direct implications for the global thermohaline circulation and the U.S. Navy. This thesis provides a qualitative and quantitative analysis of the freshwater export from the Arctic Ocean through the Canadian Arctic Archipelago (CAA) and the Fram Strait into the deep-water formation region of the Labrador Sea, using model data from 1979 to ... |

|
| The goal of this study is to assess models for Deep Convection with special emphasis on their use in coarse resolution ocean general circulation models. A model for deep convection must contain both vertical transport and lateral advection by mesoscale eddies generated by baroclinic instabilities. The first process operates mostly in the initial phases while the second dominates the final stages. Here the emphasis is on models for vertical mixing. ... |

|
 | The hydrographic structure of the Labrador Sea during wintertime convection is described. The cruise, part of the Deep Convection Experiment, took place in February-March 1997 amidst an extended period of strong forcing in an otherwise moderate winter. Because the water column was preconditioned by previous strong winters, the limited forcing was enough to cause convection to approximately 1500 m. The change in heat storage along a transbasin section, relative to ... |

| Through the Denmark Strait flows one of the most remarkable currents of the world's oceans. Roughly 3 million cubic meters per second of dense water formed in the Nordic and Arctic Seas spills over the ridge between Greenland and Iceland and cascades more than 2000 m downwards into the North Atlantic supplying a deep boundary current system that extends through the Labrador Sea, down the eastern coast of North America, ... |

| In winter 1997 a broad-scale hydrographic survey of the Labrador Sea was done during the period of active convection. This was part of the ONR- sponsored Deep Convection Accelerated Research Initiative (ARI) to study the dynamics of convective overturning. We observed convection both in the interior of the Labrador Sea as well as in the western boundary current, which produced two different vintages of water. Data collected later in the ... |

| This thesis develops and demonstrates methods of classifying ocean processes using an underwater moving platform such as an Autonomous Underwater Vehicle (AUV). The "mingled spectrum principle" is established which concisely relates observations from a moving platform to the frequency-wavenumber spectrum of the ocean process. For classifying different processes, an AUV is not only able to jointly utilize the time-space information, but also at a tunable ... |

|
| Deep-open ocean convection, the process by which vigorous vertical mixing occurs down to great depths in response to wintertime surface buoyancy losses in the sub-polar seas, is a significant mechanism of water mass transformation. The resultant newly mixed deep water masses form a component of the thermohaline circulation, and hence it is essential to understand the deep convection process if the variability of the meridional circulation, and associated climate fluctuations ... |

Three- dimensional non-hydrostatic numerical simulations were used to examine the response of individual eddies and groups of mesoscale eddies to surface cooling and convection. The mesoscale eddies are destabilized by the convective mixing, ... |

This will lead to an improved understanding of the upper ocean, whose properties change so rapidly with time. This fine-scale oceanic turbulence is also important to larger scale circulations and the mixing of water masses. Our objective is to study convection and its context: the physics of wintertime breakdown ... |
