High Frequency Acoustic Propagation Studies and Thermal Microstructure

Abstract

The long-range scientific objective of this program is to understand the environmental effects of oceanic microstructure on the propagation of high frequency sound in the ocean. The specific goal of this program was to develop a non-invasive in-situ technique for the observation of thermal microstructure which was based upon the thermal dependence of the Raman scatter of light. The hypothesis that we sought to explore was whether our multispectral low-light-level color camera (LUMIS) could be used to image the Raman emission spectra in a way which would allow the inference of thermal microstructure to a scale of 1 cm^3 and to a thermal resolution of .01 degrees C.
