I have 12 years of 1 min frequency tide/sea level data. Is there any tool box to calculate, Highest Astronomical tide level , Mean high water spring ,mean high water neap, mean low water neap, mean high water spring, lowest astronomical tide level, Seasonal variation. Highly appreciate your quake response.

Hi Indika,
if you have a water level record of 12 years, you can use the Rich Pawlowicz's T-Tide Matlab toolbox to analyze your data.
The toolbox can be downloaded from Pawlowicz's page:
I little late, but I hope this toolbox can be useful to other people, interested in tides.

The programe generated result shows as following, tide freq , amp , amp_err , pha , pha_err , snr,
Then you have to calculate using each componant S2,M2,K1,O1.....etc, 2(m2+S2) = Spring, 2(m2-S2)= Neap, form factor =ratio of K1+o1 to m2+s2, please read : Hicks, S. D. (2006). Understanding Tides.
