PIE LTER measurements of water column depth at 15 minute intervals in the Parker River near Rt 1A bridge, Newbury, MA, year 2002. Water depths are relative to the sonde pressure transducer and not associated with a datum.

Abstract: 

PIE LTER, year 2002, 15 minute readings of water column depth in the lower Parker River Estuary at  Fernalds Marina bulkhead off Rt. 1A., Newbury, MA. Water depths are relative to the sonde pressure transducer and not associated with a datum.

Methods: 

Measurements are made using a YSI 6600 water quality sonde and YSI 6200 Data Collection Platform (DCP) with data radio telemetered to the PIE LTER Rowley field station. YSI Sonde water level sensor consists of a vented level depth sensor (stainless steel strain gauge). For deployment of the sonde, a Schedule 40, four inch diameter PVC pipe was attached vertically to a piling off the bulkhead off Fernalds Marina on the Parker River. The pipe extended to the Parker River water column and the sonde was lowered into the pipe until it rested on a bolt which had been screwed through the pipe near the base/bottom of the pipe. The pipe was removed each Winter due to ice rafting and reinstalled each Spring once the ice had moved out. Each Spring the pipe was reinstalled in approximately the same vertical space with the intention of relating the relative water level measurements to a datum such as NAVD88.
