Research in Intensity Vector Acoustics
Abstract
Our research in Intensity Vector Acoustics is grounded in both numerical modeling and at-sea observation. For the latter we use a system known as the Intensity Vector Autonomous Recorder (IVAR-2) which records four coherent channels of acoustic data continuously, one channel for acoustic pressure and three channels for acoustic acceleration from which acoustic velocity is obtained.This proposal outlines five primary research objectives involving vector acoustics. These are:(1)Towards understanding the New England Mud Patch deep sediment layer structure(2)Use of the Hankel transform for geoacoustic inversion of vector acoustic data using both source tow and ship data(3)Towards understanding the Shelf Break sub bottom structure along the Tioga transect(4)Studies on Vector acoustics properties of explosive sources deployed in the NEMP, and (5)Studies on Vector acoustic properties as related to underwater sound exposure dosage levels in fish bioacoustics
