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 ...
Extraction of uranium from seawater : Design and testing of a symbiotic system
(Massachusetts Institute of Technology, 2017)
Seawater is estimated to contain 4.5 billion tonnes of uranium, approximately 1000 times that available in conventional terrestrial resources. Finding a sustainable way to harvest uranium from seawater will provide a source ...
Characterization of underwater target geometry from autonomous underwater vehicle sampling of bistatic acoustic scattered fields
(Massachusetts Institute of Technology, 2015)
One of the long term goals of Autonomous Underwater Vehicle (AUV) minehunting is to have multiple inexpensive AUVs in a harbor autonomously classify hazards. Existing acoustic methods for target classification using AUV-based ...
A computational approach to the quantification of animal camouflage
(Massachusetts Institute of Technology, 2014)
Evolutionary pressures have led to some astonishing camouflage strategies in the animal kingdom. Cephalopods like cuttlefish and octopus mastered a rather unique skill: they can rapidly adapt the way their skin looks in ...
Autonomous & adaptive oceanographic feature tracking on board autonomous underwater vehicles
(Massachusetts Institute of Technology, 2015)
The capabilities of autonomous underwater vehicles (AUVs) and their ability to perform tasks both autonomously and adaptively are rapidly improving, and the desire to quickly and efficiently sample the ocean environment ...
Hydrodynamics of a multiple tidal inlet system : Katama Bay, Martha's Vineyard, MA
(Massachusetts Institute of Technology, 2015)
Observations, theoretical models, and a numerical model (ADCIRC) are used to investigate the effects of tides, waves, bay bathymetry, and changing inlet geometry on the hydrodynamics of the multiple-inlet Katama system, ...
