An efficient Distributed Temperature Sensing setup was designed to measure small-scale 3D temperature signatures in a water body. Distributed Temperature Sensing is a measurement technique that employs a laser signal through a fiber-optic cable to obtain distributed temperature data along the cable. The current setup consists of two cables that are woven through a PVC cage as horizontal nets. These nets have a small vertical spacing near the stream bed, since this is our region of main interest in this case. The presented dataset comprises laboratory and field studies to water bodies that are subject to thermohaline stratification. In all cases, there is a local seepage inflow through the stream bed, that has a contrasting salinity and temperature from the surface water salinity and temperature. This document describes the dataset and describes how the data was calibrated and plotted to 3D movies of the evolution of the temperature profile.
