A network of fiber optic sensors was installed 40 m deep in the ground, in the drinking water well field. The sensors are called fiber Bragg grating (FBG) sensors and they are sensitive to changes in strain and temperature at the same time. The linked manuscript explains how to calculate pressure from the strain response and isolate temperature response using autoregressive (ARX) models.
