The measurement of soil moisture, and its value in estimating soil water flux and ground water recharge has long been
limited by the challenges of measuring moisture content at the appropriate, i.e., field scale. Point sensors have
radically improved and their cost greatly reduced, but still require large numbers of independant sensors to be deployed
to adequately represent the spatial variability of soil moisture, and to estimate the actual soil water flux. The development of Raman spectra fiber optic sensing of temperature for industrial applications has led to significant
applications in the measurement soils and soil physics. Distributed temperature sensing (DTS), with the capacity to record temperatures
at almost an infinite number of points in the soil profile, and at high temporal resolution, has significantly expanded the
use of soil temperature to infer soil moisture, soil water flux, soil heat flux and basic soil heat transfer processes. In this
work, we will review the current state of DTS applications in soils, with recent results from this summer's field
campaigns, where laboratory-confirmed develops are being tested under harsh field conditions.
