PROVISIONAL DATA SUBJECT TO REVISION

Click to hidestation-specific text

This station is operated in cooperation with:
   NYS Department of Environmental Conservation


LOCATION.--Lat 40°34'25", long 73°53'08" referenced to North American Datum of 1927, Kings County, NY, Hydrologic Unit 02030202, at Metropolitan Transportation Authority Marine Parkway Gil Hodges Memorial Bridge, near Floyd Bennett Field.
PERIOD OF RECORD.--Elevation record October 2002 to current year. Discharge record November 2014 to current year.
GAGE.--Water-stage recorder and acoustic velocity meter. Datum of gage is NGVD of 1929. Acoustic velocity meter provides 6-minute-interval readings collected from near mid-water depth.
REMARKS.--Elevation records excellent, except those for Oct. 2, 15-20, 22-23, Oct. 28 to Nov. 3, Nov. 7-10, Nov. 12 to Jan. 5, Jan. 9-10, 13, Mar. 27-30, and Apr. 2 to June 14, which are good; and those for Oct. 1, 3-14, 21, 24-27, Nov. 4-6, 11, Jan. 6-8, 11-12, Jan. 14 to Mar. 26, and Mar. 31 to Apr. 1, which are fair. Satellite and telephone elevation, velocity, and sensor depth telemeter at station.
EXTREMES FOR PERIOD OF RECORD.--Maximum elevation, 7.58 ft, Aug. 28, 2011; minimum elevation, -5.23 ft, Mar. 9, 2005.
EXTREMES OUTSIDE PERIOD OF RECORD.--Storm tide of Dec. 11, 1992, reached an elevation of 8.9 ft, from high-water mark at site 0.5 mi south-southeast.
PERIOD OF DAILY RECORD1.-- WATER TEMPERATURE: November 2014 to current year.
SALINITY: November 2014 to current year.
TURBIDITY: November 2014 to current year.
INSTRUMENTATION1.--Water-quality monitor provides 6-minute-interval readings collected from near mid-water depth. Salinity record computed from specific-conductance readings.
REMARKS1.--Satellite and telephone telemeter for water temperature, specific conductance, turbidity, and sampling depth parameters at station.

Peak Flow and Stage Information

Station Picture

Elevation (observed) and tide elevation (predicted) for this station are reported to NGVD 1929. To convert data to NAVD 1988 subtract 1.10 ft. To convert data to MLLW datum add 1.96 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.
