This new remote sensing technology
“is like Doppler weather radar for fish”
because it
(1) Instantaneously detects, images and continuously monitors fish population and population density over continental-shelf scales
and so
(2) reveals the detailed behavior of fish schools over wide areas.
It will be used to explore marine biology in the Gulf of Maine in 2006, as part of the Census of Marine Life Program, with support from the Sloan Foundation, the National Oceanographic Partnership Program and ONR.
