Glider-based Measurements of Acoustic Tomography Signals:Modeling and Experiment in the Canada Basin and Philippine Sea.
Abstract
Ocean acoustic tomography and propagation measurements have been made over the past few decades using moored acoustic sources and fixed arrays of hydrophone receivers. Mobile Seagliders equipped with acoustic recorders have potential to complement fixed measurements and increase the resolution of a tomography array. As part of this project, two Seagliders will be deployed in the vicinity of a tomography array in the Canada Basin to collect environmental data and acoustic receptions at a variety of ranges from moored sources to study how changes in sea ice and the water column affect acoustic propagation. These data, along with a similar dataset collected in the Philippine Sea, will also be used to study the range-dependence of oceanic and acoustic variability, to efficiently model this variability, and to advance the state of the art in underwater glider navigation and positioning.
