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 ...
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 ...
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 ...
