To reach the tidal bench marks, from the Nausori Airport, make a right turn
(toward Suva). Upon reaching the main road, the drive into Suva takes about 30
minutes, so stay on the main road and keep driving. You will eventually go over
a pass and see Suva below. The road changes names from Ratu Mara Road to
Endinburgh Drive upon entering Suva. When you hit a round about at the bottom
of the hill, continue going straight. The road bears left and passes the bus
terminal and public market. Before the road bears left again, take the turn off
to allow you to go right. This will put you on Usher Street and you will see
the entrance to Kings Wharf directly ahead. Normally you would check in with
Hydrographic Office before going to the gauge. This is rather necessary because
they will help you obtain a pass to gain entrance into the pier area.

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 local island datum. 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/.
