TREX13: Mid-Frequency Measurements and Modeling of Scattering by Fish

Abstract

The research was based, in part on a large multi-PI experiment that took place in April/May, 2013 off of Panama City, Florida. The program was led by APL:UW (Tang/Heffner) and details of the experiment are in their reports and publications. A key element of the fish component was the measurements of mid-frequency reverberation from a fixed source and receiver. The measurements were made nearly continuously 24 hours per day. Another key element to the fish effort is the UW-led(Home) high frequency surveys of fish in the area. The WHOI-led (Stanton) effort focussed on designing the fish component of th experiments and identifying echoes that were due to the fish that were presumed to be present. Although the original proposed approach also included analyzing and modeling the mid-frequency reverberation data in terms of the fish echoes, funding was stopped before that activity could begin. Stanton oversaw this fish component of the research and participated in all phases of the research. Jones conducted data analysis of the fish echoes. The analysis included characterizing the echoes in terms of their spatial distribution and how that distribution changed in time (day to night and within the night). These efforts were leveraged by those of other PIs in the TREX13 program through participation in regularly scheduled workshops.
