Abstract:Measurements of water column depth at 15 minute intervals in the upper Parker River at Middle Road (Thurlow's Bridge), Byfield, MA, year 2005. Middle Road is located 18.5 km up the estuary from the 0 km reference at the mouth of Plum Island Sound. Water depths are relative to the sonde pressure transducer and are not associated with a datum.
