the world’s largest Exclusive Economic Zone (EEZ), the United States
enjoys the benefits of a multi-billion dollar commercial fishing industry. Along
with these benefits comes the enormous task of assessing the status of the nation’s
commercial fish stocks. At present, many of the most valuable commercial fish stocks
are assessed using acoustic surveys conducted from manned survey vessels. The expense
and limited availability of ship time often compromise the quantity and quality
of the acoustic stock assessment data being collected.<o:p></o:p></span></p>

Wave Gliders harness wave energy for propulsion and solar energy to power their
communications, control, navigation, and environmental sensing systems. This
unique utilization of wave and solar energy allows Wave Gliders to collect
ocean environmental data sets for extended periods of time.<o:p></o:p></span></p>

technology for Wave Gliders that enable them to collect multifrequency,
