Field Activity 2006-018-FA

Identifier 2006-018-FA
Purpose Reconnaissance-level surveying of submarine groundwater discharge indicators in lower Potomac River Estuary and western shore of Chesapeake Bay.
Location Maryland, Potomac River estuary, Chesapeake Bay, United States, North America, North Atlantic;
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.
Comments Additional cruise on Chesapeake Eastern Shore likely in summer 2007.
