A method for on-line water current velocity estimation using Lol-cost autonomous underwater vehicles
(Massachusetts Institute of Technology, 2020)
Advances in the miniaturization of microelectronics has greatly contributed to the proliferation of small, low cost autonomous underwater vehicles (AUVs). These affordable vehicles offer organizations a flexible platform ...
A study of ocean wave statistical properties using nonlinear, directional, phase-resolved ocean wave-field simulations
(Massachusetts Institute of Technology, 2010)
In the present work, we study the statistics of wavefields obtained from non-linear phase-resolved simulations. The numerical model used to generate the waves models wave-wave interactions based on the fully non-linear ...
Demonstration of passive acoustic detection and tracking of unmanned underwater vehicles
(Massachusetts Institute of Technology, 2018)
In terms of national security, the advancement of unmanned underwater vehicle (UUV) technology has transformed UUVs from tools for intelligence, surveillance, and reconnaissance and mine countermeasures to autonomous ...
Field measurements of a swell band, shore normal, flux divergence reversal
(Massachusetts Institute of Technology, 2011)
Throughout this thesis we will discuss the theoretical background and empirical observation of a swell band shore normal flux divergence reversal. Specifically, we will demonstrate the existence and persistence of the ...
Rapid extraction of dissolved inorganic carbon from seawater and groundwater samples for radiocarbon dating
(Massachusetts Institute of Technology, 2012)
The focus of this thesis is the design and development of a system for rapid extraction of dissolved inorganic carbon from seawater and groundwater samples for radiocarbon dating. The Rapid Extraction of Dissolved Inorganic ...
Measurements and dynamics of multiple scale bedforms in tidally energetic environments
(Massachusetts Institute of Technology, 2018)
The presence of superimposed bedforms, where smaller bedforms exist on larger bedforms, is ubiquitous to energetic tidal environments. Due to their wide range in scale, it is difficult to simultaneously observe these ...
