domain and dart buoys:

DARTs = [21414, 21419, 21418, 21413, 52403, 52406, 51425, 51407,
        46404, 46407, 46411, 46412, 43412, 43413, 32411, 32412,32401]

as shown in the respective notebook, im deleting some of them:

• 21401 has contents with len = 0
• 55012, 32413 have contents but only header

[jgalazm]

Time series look like this

I'm removing the following due to lack of data:

• 46412
• 21413
• 21418
• 21419

So only these are left

[jgalazm]

To filter the low frequency components I'm picking a threshold of 3 cph (20 mins) The spectras look like this

Seems like a nice criteria

[jgalazm]

The resulting time series fior low and high frequencies are here:

The vertical spacing between the mean values of each tseries is 2 meters on the left and 25 cm on the right.

But these points are in shallow water. Need to implement the Green scaling law to extrapolate the data.
