USGS 01304920 MORICHES BAY AT EAST MORICHES NY

PROVISIONAL DATA SUBJECT TO REVISION

Click to hidestation-specific text
NOTICE (03/06/2019) -- This site was discontinued on March 06, 2019 due to lapse in funding. Although historic data will remain accessible, no new data will be collected unless one or more new funding partners are found. Users who are willing to contribute funding to continue operation of this tide gage should contact Rob Breault of the USGS New York Water Science Center at 518-285-5658 or dc_ny@usgs.gov.

 

LOCATION.--Lat 40°47'17.2", long 72°45'03.11" referenced to North American Datum of 1983, Suffolk County, NY, Hydrologic Unit 02030202, at U.S. Coast Guard Sector Field Office Moriches, in East Moriches.
PERIOD OF RECORD.--April 2016 to current year.
GAGE.--Water-stage recorder. Datum of gage is NGVD of 1929.
REMARKS.--Satellite and telephone elevation telemeters at station.
EXTREMES OUTSIDE PERIOD OF RECORD.--Storm tide of Oct. 30, 2012, reached an elevation of 7.41 ft, from temporary monitoring sensor.

NAVD 1988 Datum Conversion Information


Elevation observations and tidal predictions for this station are reported to NGVD 1929. To convert data to NAVD 1988 subtract 1.00 ft. To convert data to MHHW datum subtract 2.15 ft. To convert data to MLLW datum add 0.35 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.
MHHW is mean higher high water, which is a site-specific datum determined by averaging the highest of the 2 high 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.
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.
