Title: FEATS: Fundamental Estimations of Acoustic Target Strength

Project Year and Number: 1999: 99468-BAA

Other Fiscal Years and Numbers for this Project: 2001: 01468-CLO, 1998: 98468-BAA

Principal Investigator (PI): Gary Thomas, Rosenstiel School of Marine and Atmospheric Sciences, U. Miami

Assisting Personnel: Jay Kirsch, Dick Thorne

Research Location: Prince William Sound

Restoration Category: Research

Injured Resources Addressed: Pacific Herring

Abstract: To scale acoustic survey data from relative units (dB) to absolute units (kg/m3), knowledge of the individual fish's target strength (TS) by size is required. This project will conduct experiments to measure the TS of Pacific herring and sand lance in Prince William Sound. FY 99 will concentrate on the development of experimental apparatus and experimental logistics and the application of these to measure Pacific herring TS and sand lance TS. TS-to-length regressions will be calculated and applied to past surveys in Prince William Sound to obtain more accurate density and biomass estimates, and will serve future acoustic survey efforts of these species in coastal Alaska.
