#8810 3 Apr 2014 Approved Notes: Hach #2 used. Lead too short to take deeper observations. Very strong outward current.
Readings from south end of jetty to enable use of van Doorn.

#8760 6 Mar 2014 Approved Notes: Readings were taken at the southern end of the jetty, as the current was too strong at the side of the jetty to use the van Doorn to collect bottom water sample.
The salinity was checked but the meter did not require calibration

#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
