IMSL and MLW datum adjustments based on Station 8722125, Vero Beach FL (270 37.9' N, 800 22.3' W)

I To use the table, start at the Datum Input columns at the top of the table to select the datum the data is presented in. Staying in the datum input column, move down the table rows to the desired Datum Output presented in the left side of the table. The value intersecting the Datum Input column and Datum Output row is the conversion between the datums.

Definitions:

MSL = Mean Sea Level NGVD29 = National Geodetic Vertical Datum of 1929 NAVD88 = North American Vertical Datum of 1988 MLW = Mean Low Water ft = feet m =meters Sample Conversions:

0 ft-NAVD88 = 3.35 ft-Plant Datum (0 ft + 3.35 ft = 3.35 fi) 2 ft-MSL = 1.088 ft-NAVD88 (2 ft - 0.912 ft = 1.088 fi)

This convention was chosen as landfall at 1 RMW south of the site maximizes the wind speed at PSL. A landfall location of +1 RMW indicates that the hurricane eye passes over PSL. A landfall location of-1 indicates the hurricane eye passes 2 RMW south of PSL.
