Abstract
The sub-surface temperature of a body of water, such as an ocean, is measured remotely by directing a laser beam into a body of water and analyzing the Raman backscatter produced by the water. The Raman backscatter contains information which, when processed, indicates the water temperature at various depths. Precise temperature measurements may be made by separately detecting and measuring the polarization ratio at different wavelength intervals throughout the Raman band and measuring the differential diffuse attenuation coefficient using range-gated Raman backscatter techniques on a wavelength by wavelength basis.
