1) We calculated the astronomical tide levels at 35 points on the coasts of
Java Island, Indonesia from the beginning of July 2006 through the end
of December 2006 by using 6-10 harmonic constants of the tidal components
M2, S2, O1, K1, etc. given by the Hydrographic and Oceanographic Department,
the Japan Coast Guard, Tsukiji, Tokyo.
We expect that those data will be useful in compensation of the astronomical tide component for the data obtained as the results of field surveys.
2) Numerals in each line denote as
follows:
Year, Month, Day, Time [hour], Sea Level [cm].
The time is given in the local time for each station, and is not the universal time.
3) The calculated tide levels are height above the lowest low level at each ports, which is generally situated at Zo, the sum of the amplitude values of four principal tide components (M2, S2, K1, and O1) below the mean sea level.
