To reach the tidal bench marks from the intersection of Highways 14 and 52 in
Ponce, proceed south/west on Highway 52, which turns into Highway 2 West towards
Mayaguez, for 14.0 km (8.7 mi) to the intersection with Highway 127 west, then
continue west on Highway 127 for 2.7 km (1.7 mi), then south on Highway 337 for
3.78 km (2.35 mi) and go through the first guard gate, bear to the right and
continue until the road splits, then stay left and continue to the second guard
gate to the EcoElectrica power plant in Penuellas, then continue 0.6 km (0.4 mi)
to the right after coming through the gate and eventually weave around to the
third guard gate and the base of the LNG pier. The bench marks are located on
the pier. The tide gage was located near the SW end of the pier.

Mean Sea Level (MSL) is a tidal datum determined over a 19-year National
Tidal Datum Epoch. It pertains to local mean sea level and should not be
confused with any other fixed island datum.
This tide station location has a defined island datum (PRVD02). Island datums
are specific fixed geodetic datums whose elevation relationship to local MSL
and other tidal datums may not be consistent from one location to another.
The Vertical Mark Number (VM#) and PID# shown on the bench mark sheet are unique
identifiers for bench marks in the tidal and geodetic databases, respectively.
Each bench mark in either database has a single, unique VM# and/or PID# assigned.
Where both VM# and PID# are indicated, both tidal and geodetic elevations are
available for the bench mark listed. The NGS's Integrated Data Base (IDB PID)
provides geodetic datum based on traditionally leveled and bluebooked ties to
the National Spatial Reference System(NSRS) https://www.ngs.noaa.gov/datasheets/.
The NGS Online Positioning User Service (OPUS PID) provides geodetic datum based
on GPS position & tie it to the NSRS https://www.ngs.noaa.gov/OPUS/.
The PRVD02 elevation is shown on the Elevations of Tidal Datums Table Referred
to MLLW only when two or more of the bench marks listed have PRVD02 elevations.
The PRVD02 elevation relationship shown in the table is derived from an average
of several bench mark elevations relative to tide station datum. As a result of
this averaging, PRVD02 bench mark elevations computed indirectly from the tidal
datums elevation table may differ slightly from PRVD02 elevations listed for
each bench mark in the NGS database.
