Abstract
Intrinsic changes in glass due to temperature may be detected by comparing the Stokes and Anti-Stokes Raman Back Scatter. Employed along a fiber optic, one may in this way measure temperature along distances >10,000 m with 1 m resolution. This can then be used to make multi-scale observations of complex environmental processes. We will present examples of double diffuse turbulent structures in deep mine shafts, lake dynamics, and rivers.
