  1. Linking Thermal Remote Sensing and Ground-based Studies to Determine Scales, Character, and Distribution of Submarine Groundwater Discharge Jacque Kelly University of Hawaii at Manoa

  2. SGD and the Subterranean Estuary After Oki et al 1999

  3. SGD Tracers

  4. Thermal Infrared Surveying Jacque GPS-INS Infrared Camera 7.5-13.5 μm Sea Surface Water Temperature Top < 1 mm of water 3.2 m resolution 0.5°C resolution 2133 m Mike & Bob Live Data Thermistors

  5. Radon Surveying Air-Water Exchanger Multi-parameter Meter RAD-7 GPS & Depth Sounder Submersible Pump RAD-7 Air-Water Exchanger

  6. After Johnson et al 2008

  7. SGD: Scales, Character, Distribution Easy determination of surface plume size Numerous locations along coastline Point source vs diffuse flow Ocean-mixing characteristics Tidally-modulated flow? After Johnson et al 2008

  8. PEARL CITY PENINSULA HOUSING PEARL CITY PENINSULA HOUSING

  9. PEARL CITY PENINSULA HOUSING PEARL CITY PENINSULA HOUSING

  10. SGD: Scales, Character, Distribution Rn concentration higher at intermediate depth than at surface High Rn concentration Extends from the coastline about 65 meters at depth Lens of fresher water underneath the main seawater column

  11. Conclusions • Linking air-based and ground-based techniques provides a more comprehensive view of SGD than either technique alone • Provide clues about the scale, character, and distribution of SGD over multiple time scales and investigation scales (local to regional)
