Scientific Purpose/Goals: Radon mapping and discrete water sampling in West Falmouth Harbor corroborated by infrared fly-over to detect low-temperature groundwater discharge organized with collaborator Ann Giblin, MBL.


Start Date: 2006-08-09

Start Port/Location: West Falmouth Harbor, MA

End Date: 2006-08-10

End Port/Location: West Falmouth Harbor, MA

Equipment Used: RAD7 radon detection instrument, YSI multiparameter sonde, Digital camera, GPS (wh)

Information to be Derived:

Summary of Activity and Data Gathered: Mapping of water-column radon activity throughout all of West Falmouth Harbor took place on two consecutive days on August 9 and 10, each time covering a large portion of the harbor during a low spring tide and with the same equipment setup as on July 7. No discrete radon samples were collected during this field effort, but 15 water-column samples were collected and filtered for later radium analyses using a bilge pump to pull water into containers carried aboard an MBL owned and operated boat. This event was coordinated with simultaneous thermal imaging conducted from a small aircraft (carried out during the afternoon of August 10 by scientists from the EPA Narragansett Bay lab).
