ADDITIONAL INFORMATION

For this site, "Field groundwater-level measurements"
displayed in "Table of data" or "Tab-separated
data" formats indicate water levels above two different vertical
datums for each measurement date and time, although only one of the
datums currently is appropriate and accurate for the measurement. In
general, the appropriate vertical datum is date dependent. The
appropriate datum for water levels measured before about 2005 to 2010
is LMSL (local mean sea level), whereas the appropriate datum for water
levels measured after about 2005 to 2010 is the most current vertical
datum available (GUVD04 for Guam; NMVD03 for Saipan). The dates that
are appropriate for each datum are site specific and have yet to be
determined for this site. Also, the vertical datum indicated in the
graphical output of "Field groundwater-level measurements"
may reflect an incorrect datum, depending on the range of dates being
displayed.
