Summary: 4 September, Bratton drives gear down from Woods Hole and Crusius flies down to scout area; 5 September, Worley, Foster, Erban arrive in Solomons, set up gear on boat, troubleshoot; 6 September, seismics/CRP/radon mapping from mouth of Patuxent River into Potomac River and St. Mary's River to Dennis Pt. Marina (lines #1-6), set up RAD7 and YSI for radon time series at marina, PM Cross arrives; September 7, surveys with all systems up Maryland shore of Potomac mainstem and zigzag back downstream (lines # 7-19); September 8, surveys with all systems up part of MD shore and mostly VA shore with final crossing back north (lines # 20-26), transit back to Solomons with 5 mid-channel (Potomac) radium samples and YSI profiles, demobe gear from boat; September 9, Crusius and Bratton back to Dennis Pt. Marina in AM to collect time-series gear and four groundwater samples, others head to airport, later Crusius to airport and Bratton drives pickup and trailer with gear back to Woods Hole.
