Wind speed and direction, wave height and period, air temperature,
sea surface temperature, and barometric pressure are recorded
by instruments maintained at Ambrose Light (Station ALSN6
located at 40º27.6' N., 73º49.8' W) and Long Island 33 nm
south of Islip (Station 44025 located at 40º15.0' N 73º10.0'
W.) by the National
Data Buoy Center (NDBC)
1). Ambrose Light is a tower and the anemometer height
is 49 m above sea level. Long Island 44025 is a 3 m discus
buoy and the anemometer height is 5 m above sea level. Data
was obtained from Station
44025 (www.ndbc.noaa.gov/station_page.phtml?station=44025) and Station
ALSN6 (www.ndbc.noaa.gov/station_page.phtml?station=alsn6) at one-hour intervals.
Coastal Sea Level
Sea level was recorded by instruments maintained at Sandy
Hook (Station 8531680 located at 40º 28.0' N., 74º 0.6' W.,
1) by the National
Ocean Survey (www.nos.noaa.gov/). Data from Sandy
Hook (co-ops.nos.noaa.gov/data_options.shtml?stn=8531680+Sandy+Hook,+NJ) was obtained at one-hour intervals. These elevations
were converted to equivalent bottom pressure by adding atmospheric
pressure as measured at Ambrose Light (Station ALSN6) (www.ndbc.noaa.gov/station_page.phtml?station=alsn6), see above).
