Observations and modeling of sand transport in a wave dominated environment
(Massachusetts Institute of Technology, 1998) -
Observations and modeling of wave-acceleration-induced sediment transport in the surfzone
(Massachusetts Institute of Technology, 2004)Onshore sediment transport and sandbar migration are important to the morphological evolution of beaches, but are not understood well. Here, a new model that accounts for accelerations of wave-orbital velocities predicts ... -
Observations of wave-mean flow interaction in the Pacific equatorial undercurrent
(Massachusetts Institute of Technology, 1991) -
Ocean bottom seismic scattering

On the diffraction of free surface waves by a slender ship
(Massachusetts Institute of Technology, 1981) -
On the nature of explosively developing cyclones in the Northern Hemisphere extratropical atmosphere

On the pathways of the return flow of the meridional overturning circulation in the tropical Atlantic
(Massachusetts Institute of Technology, 2002)A numerical model of the tropical Atlantic ocean is used to investigate the upper layer pathways of the Meridional Overturning Circulation (MOC) in the tropical Atlantic. The main focus of this thesis is on those parts of ... -
Optimal chartering and investment policies for bulk shipping
(Massachusetts Institute of Technology, 1992) -
Optimal mode localization in disordered, periodic structures

Overflows and upper ocean interactions : a mechanism for the Azores current
(Massachusetts Institute of Technology, 2006)The oceanic response to overflows is explored using a two-layer isopycnal model. Overflows are a major source of the dense water of the global deep ocean, originating from only a few marginal seas. They enter the open ocean ... -
The paleoceanography of the Bering Sea during the last glacial cycle
(Massachusetts Institute of Technology, 2006)In this thesis, I present high-resolution stable-isotope and planktonic-fauna records from Bering Sea sediment cores, spanning the time period from 50,000 years ago to the present. During Marine Isotope Stage 3 (MIS3) at ... -
Parametric identification of nonlinear stochastic systems applied to ocean vehicle dynamics.
(Massachusetts Institute of Technology, 1971) -
A Pareto frontier for full stern submarines via genetic algorithm
(Massachusetts Institute of Technology, 1998) -
Performance analysis of subaperture processing using a large aperture planar towed array
(Massachusetts Institute of Technology, 2004)In recent years the focus of passive detection and localization of submarines has moved from the deep ocean into the littoral regions. the problem of passive detection in these regions is complicated by strong multipath ... -
Performance bounds on matched-field methods for source localization and estimation of ocean environmental parameters
(Massachusetts Institute of Technology, 2001)Matched-field methods concern estimation of source location and/or ocean environmental parameters by exploiting full wave modeling of acoustic waveguide propagation. Typical estimation performance demonstrates two fundamental ... -
Periodic propeller forces in unsteady flow
(Massachusetts Institute of Technology, 1964) -
Persistent anomalies of the extratropical Northern Hemisphere wintertime circulation
(Massachusetts Institute of Technology, 1982) -
Petrologic and microstructural constraints on focused melt transport in dunites and the rheology of the shallow mantle
(Massachusetts Institute of Technology, 2004)Observations at mid-ocean ridges indicate that magmas are focused to the ridge axis by a network of porous dunites in near chemical isolation. This thesis investigates several of the outstanding questions regarding the ...
