Submarine Fresh Water Outflow Detection with a Dual-Frequency Microwave and an Infrared Radiometer System
The surface area above submarine springs of fresh water exhibit temperatures of 4°C and salinities of 5 °/oo lower than the surrounding sea waters. The Langley multifrequency radiometer system which earlier demonstrated (Blume et al, 1978) an accuracy of 0.3°C and 1 °/oo in remotely detecting the surface temperature and salinities respectively was used to detect submarine fresh water springs. The first mission on February 4, 1978 consisted of overflight measurements over 3/4 of the coastal areas around the island of Puerto Rico. During the second mission on February 6, 1978 special attention was directed to the northwest portion of Puerto Rico where several submarine springs had been reported.
