Collecting data over a submarine groundwater vent

Detailed Description

An inflatable boat floating above a submarine groundwater vent was used as a multi-day mooring platform for making time-series measurements of the naturally occurring groundwater tracers radon (222Rn) and thoron (220Rn). Gray surface buoys closer to the beach mark locations of thermistor arrays and wave/tide gauges. The hotel directly behind the boat housed a thermal-infrared (TIR) camera making time-series measurements of sea-surface temperature to document variations related to groundwater discharge.
