Sea level: In this report, "sea level" refers to the National Geodetic Vertical Datum of 1929 (NGVD of 1929), a geodetic datum derived from a general adjustment of the first-order level nets of both the United States and Canada, formerly called Sea Level Datum of 1929.
Horizontal Datum: Latitude and longitude coordinates are referenced to the North American Datum of 1927 (NAD of 1927).
Temperature: Temperature is given in degrees Fahrenheit (°F), which can be converted to degrees Celsius (°C) as follows:
°C = 5/9 (°F - 32)
