Measurements of sediment redox potential at 4 stations along a transect of the Parker River and near the mouth of the Rowley River, Newbury and Rowley, Massachusetts during 1993 and 1994.
EXPERIMENTAL DESIGN AND METHODS: Sediment cores were obtained in the field and transported to the laboratory for analysis within 24 hr. Sediment redox potential (Eh) was measured in 6 cm diameter cores using a platinum Eh probe coupled with a calomel reference electrode. The Eh electrode was lowered to designated depths in the core and allowed to react for 15 minutes or until readings were stable. Reading were corrected for the standard potential of the electrode-reference combination. By convention, depth in the sediment is given as negative values.
