New 3-D Acousto-Optic Instruments for Small Scale Oceanic Measurements by Jules Jaffe, Ed Reuss, Andrew Palowitch, Duncan McGehee and Girish Chandran Over the last several years, our research group in the Marine Physical Laboratory at Scripps Institution of Oceanography (SIO) has been developing several new underwater imaging systems for measuring both spatial and dynamic characteristics of underwater organisms. Our primary goal has been to create what we consider to be a "next generation" of ocean technology. To us, this means cameras that have fast repetition rates and good spatial resolution. We have been developing both sonar technology as well as optical methods in an effort to resolve phenomena on scales ranging from centimeters to meters (McGehee and Jaffe, 1993; Palowitch and Jaffe, 1992; Palowitch and Jaffe, in press). These include fine scale distribution of phytoplankton, behavior of zooplankton, interactions between zooplankton, and interactions between zooplankton and phytoplankton. We now have several working prototypes. In this article we describe our progress to date.
