LIDAR and Acoustics Applications to Ccean Productivity

The prospect of the National Aeronautics and Space Administration developing a second generation Ocean Color Scanner has produced the need for coincident in A= scientific measurements which examine the primary productivity of the upper ocean on time and space scales that are large compared to the environmental scales of interest. Central to the investigation of the productivity, are questions of the vertical and horizontal variability of the biota, including the relationship between chlorophyll and primary productivity, the productivity of zooplankton, and the dynamic interaction between phytoplankton and zooplankton, and between these populations and the physical environment. To provile these measurements, a towed submersible must be constructed which can aceommodate both an underwater LIDAR instrument and a multifrequency sonar. This report includes the requirements for the submersible, and the instrumentation necessary to perform these measurements, and describes the optical and acoustical technology required to develop that instrumentation.
