Question 2 (10 marks)
The sea level measurements were observed at a tide-gauge station
in North Point over a period of 24 hours with a 1-hour interval.
Propose a method how to model a periodical signal (approximately
occurring every 12 hours) in the tide-gauge record showing high and
low tides. Provide a numerical example by using 24 values of the
mean hourly sea level measurements. The result should be given in
terms of the amplitude of the tide (in cm) and its
uncertainty.
