Acoustic scattering by axisymmertic finite-length bodies with application to fish : measurement and modeling
(Massachusetts Institute of Technology, 2002)This thesis investigates the complexities of acoustic scattering by finite bodies in general and by fish in particular through the development of an advanced acoustic scattering model and detailed laboratory acoustic ... -
Adaptive sampling of transient environmental phenomena with autonomous mobile platforms
(Massachusetts Institute of Technology, 2019)In the environmental and earth sciences, hypotheses about transient phenomena have been universally investigated by collecting physical sample materials and performing ex situ analysis. Although the gold standard, logistical ... -
Experimental visualization of the near-boundary hydrodynamics about fish-like swimming bodies
(Massachusetts Institute of Technology, 2001)This thesis takes a look at the near boundary flow about fish-like swimming bodies. Experiments were performed up to Reynolds number 106 using laser Doppler velocimetry and particle imaging techniques. The turbulence in ... -
Geoacoustic inversion by mode amplitude perturbation
(Massachusetts Institute of Technology, 2007)This thesis introduces an algorithm for inverting for the geoacoustic properties of the seafloor in shallow water. The input data required by the algorithm are estimates of the amplitudes of the normal modes excited by a ... -
Geoacoustic inversion in laterally varying shallow-water experiments using high-resolution wavenumber estimation
(Massachusetts Institute of Technology, 2002)Sound propagation in shallow water is highly dependent on the interaction of the sound field with the bottom. In order to fully understand this problem, it is necessary to obtain reliable estimates of bottom geoacoustic ... -
Morphological approaches to understanding Antarctic Sea ice thickness
(Massachusetts Institute of Technology, 2020)Sea ice thickness has long been an under-measured quantity, even in the satellite era. The snow surface elevation, which is far easier to measure, cannot be directly converted into sea ice thickness estimates without ... -
Physically constrained maximum likelihood method for snapshot deficient adaptive array processing
(Massachusetts Institute of Technology, 2003) -
Seafloor ripples created by waves from hurricane Ivan on the west Florida shelf
(Massachusetts Institute of Technology, 2006)Recent studies have shown that the presence of sand ripples on the seabed improves sonar detection of buried mines at sub-critical angles. Sidescan sonar data of ripples off on the west Florida shelf were collected as part ... -
Sediment deposition in the lower Hudson River estuary
(Massachusetts Institute of Technology, 1999) -
Statistical models and decision making for robotic scientific information gathering
(Massachusetts Institute of Technology, 2018)Mobile robots and autonomous sensors have seen increasing use in scientific applications, from planetary rovers surveying for signs of life on Mars, to environmental buoys measuring and logging oceanographic conditions in ...
