The water temperature data for this station are temporary and will only be displayed for 120 days. Although the instrumentation is calibrated at least once/year, the temporary classification means that documented routine inspections and other quality assurance measures are not performed that would make the data acceptable for archival, retrieval, or future use in general scientific or interpretive studies.
This tide gage is operated as part of the New Jersey Tide Telemetry System. The system is cooperatively funded by the State of New Jersey and the USGS.
LOCATION.--Lat 39°23'01", long 75°21'01" referenced to North American Datum of 1983, Greenwich Township, Cumberland County, NJ, Hydrologic Unit 02040206, on private pier at Greenwich Marina, 1,100 ft upstream of Pine Mount Creek, 0.7 mi southwest of Greenwich, 4.4 mi upstream of mouth and Delaware Bay, and 6.9 mi southwest of Bridgeton.
PERIOD OF RECORD.--Annual maximum tide, water year 1979-2001. Unpublished fragmentary gage-height record, Oct 28, 1996 to Apr 27, 2000. Continuous-record tide gage, Apr 28, 2000 to current year.
GAGE.--Tide elevation and precipitation recorder and tidal crest-stage gage. Datum of gage is at 0.00 ft NAVD of 1988. To determine approximate elevations to NGVD of 1929, add 1.34 ft. From October 1979 to September 2001, crest-stage gage located at current location (Greenwich Pier) and datum of gage at 0.00 ft NGVD of 1929. From September 2001 to January 2011, tide gage was located 0.5 mi downstream at Hancock Marina and datum of gage at 0.00 ft NAVD of 1988. Data published to NGVD of 1929 can be adjusted to NAVD of 1988 by subtracting 1.20 ft. Online annual tidal peaks have been adjusted to current datum.
