Seismo-Acoustic Remote Sensing of the Arctic Environment
Abstract
LONG-TERM GOAL(S). Transitioning of acoustic ASW technology into environmental remote sensing techniques for characterizing ice-mechanical, oceanographic, and geophysical processes, climate change, and marine mammal behavior in the Arctic. SCIENTIFIC/TECHNICAL OBJECTIVES. Fundamental understanding and modeling of the generation, propagation, and scattering of sound in and below the ice cover. The specific objective of the MIT/WHOI effort under SIMI has been to use seismo-acoustic remote sensing and subsequent inversion for characterization of ice fracturing processes and their relation to the environmental forcing. The CEAREX and SIMI field experiments have also provided a comprehensive database of experimental data important to the other environmental remote sensing potentials. Thus, a significant part of our SIMI effort has been devoted to the modeling and analysis of the recordings of the 1994 Transarctic Acoustic Transmissions (TAP). In addition we are collaborating with marine biologists on the analysis of marine mammal sounds in our database.
