PROVISIONAL DATA SUBJECT TO REVISION
This station is operated in cooperation
with:
NYS Department of Environmental
Conservation
LOCATION.--Lat 40°40'09", long 73°21'22" referenced to North American Datum of 1927, Suffolk County, NY, Hydrologic Unit 02030202, at Village of Lindenhurst Charles J. Cowan Marina, in Lindenhurst.
PERIOD OF RECORD.--July 2002 to current year.
GAGE.--Water-stage recorder. Datum of gage is NGVD of 1929.
REMARKS.--Records excellent, except those for May 17-21, 28, and May 30 to Sep. 30, which are good; and those for Oct. 1-26, which are poor. Satellite and telephone elevation telemeter at station. Interruption of record on Oct. 30 was due to malfunction of recording instrument.

Elevation (observed) and tide elevation (predicted) for this station are reported to NGVD 1929. To convert data to NAVD 1988 subtract 1.19 ft. To convert data to MLLW datum subtract 0.25 ft. These corrections vary from site to site. |

NGVD 1929
is the National Geodetic Vertical Datum of 1929, formerly called
"mean sea level" or "Sea Level Datum of
1929." NGVD 1929 was a general adjustment of the first-order
level nets fit to mean sea level at 26 tide gages in the US and
Canada.
NAVD 1988 is the North American Vertical Datum of 1988, which is a geodetic datum derived from a general adjustment of the first-order level nets fit to 1 tide gage in eastern Canada. MLLW is mean lower low water, which is a site-specific datum determined by averaging the lowest of the 2 low tides that occur each day over a 19-year tidal epoch. For tide gages with less than 19 years of record, this datum is estimated by correlation with long-term tide gages. |
