Summary: In 2017-2018, we visited a suite of about 80 springs in New York and New England (USA). We measured water temperature with a Lascar EL-WIFI-TP digital temperature logger (0.1°C precision) at the closest accessible point to the source, which was usually the reservoir inside a spring house or the outflow pipe from a spring house. When both reservoir and outflow pipe were accessible, we found that temperatures agreed to within ±0.2°C. We also measured the flow rate of the spring with a bucket and a stopwatch, with a repeatability of about ±10%.

A temperature anomaly ∆T was determined for each spring by subtracting the annual average temperature at the spring site. Annually averaged temperatures are rarely available for spring sites but are available for airports via the National Oceanic and Atmospheric Administration’s (NOAA’s) National Center for Environmental Information. We therefore used the annually averaged temperature for the nearest airport (typically ~10-20 km away), corrected to the elevation of the spring using the dry adiabatic lapse rate of 9.8°C/km.

Data was used in the following paper:
