#8705 6 Feb 2014 Approved Notes: Salinity checked, but calibration not required.
Due to the very strong outward current, dragging the van doorn and probe downstream, all samples and readings were taken from southern end of jetty.
pH meter "Upper" replaced usual meter.
Tide was very low. Large buildup of sand downstream of bridges on Ocean Grove bank
