Information to be Derived:

Summary of Activity and Data Gathered: Mapping of water-column radon activity took place in Snug Harbor on July 7 aboard a slow-moving skiff equipped with RAD7 radon detectors and a YSI sonde interfaced to a laptop computer. This effort focused on both a low-tide and high-tide circumnavigation on that day. Simultaneously, discrete water samples (14 during the low-tide and only 11 during the high-tide due to logistical difficulties) were collected for subsequent radon analysis, jointly by kayakers using a peristaltic pump to take surface water and by people in the radon mapping vessel who used a Niskin bottle to this same end.
