Hello all
I had a bit of complete relaxation time yesterday and thoughts
flowed...
I saw you could do the lot with "awk" - the unix toolkit awk command /
utility.
"Rough" first output.

Broadly "it's there"; however there are problems where the tide gauge
was mulfunctioning (a tide making 11.something m above Lowest
Astronomical Tide would if it really happened make the news!!!).
Etc.
The horizontal axis is the tide-gauge's sequential 15-minute
data-record increments in a year
(* 365 24 4) ;; 35040
I would help a more sophisticated "data-crawling" program if there
were inclination to make one.

Rich Smith
