Marine Resources Spectrometer Experiment.
Abstract
Spectral contrast ratios in the visible region of the spectrum between the radiance from fish schools and adjoining water, were obtained by an airborne spectrometer. Most of the data presented are of menhaden just after capture in a purse seine, and of natural mullet schools. These data were taken from a helicopter near the Mississippi Delta. Additional data for natural anchovy schools were obtained off the9 coast of Southern California from a seaplane. A repeatable signature for the mullet was definitely established. Useful contrast ratios were not obtained for the menhaden or anchovy schools. For the menhaden, this was due to the muddy water caused by seining operations. (Author)
