Sea Level Fluctuations in Tórshavn, Preliminary Results
TABT.K III Frequency ,Amplitude and Phase values for harmonic constituents in the
tide of TÓrshavn.The Phase is relative to the time JAN. 1 st 1973 0000 GMT. Col.
5 and 8 list the number of determinations,which for each constituent have been
used to estimate mean cind standard deviation of frequency and amplitude ,respec-
tively phase. Aliased frequencies are "backaliased" in col. 9. The last two cols
list symbol and theoretical frequency for identified frequencies.

nomic elements determining the tide are computed (ref. 12) for
the starting time. Based on this and the values of table IV,
amplitudes and phases of the constituents corrected for nodal
modulation are evaluated and the tide computed — and if
necessary plotted.
Fig 5 shows an example of prediction. The period is a week
nearly a year later than the end of the data series used in the
analysis. On the figure data for the period from the tide gauge
have been plotted.
