Hi
There are some interesting interactions between liquid (sea) tides and solid
tides. Big blobs of water sloshing around in the ocean
really close to shore do turn out to have an effect. Not a big deal for those
of us wise enough to live well inland :) Probably a lot of fun
to plot and validat
I'm using code from a Fortran program called solid.f that I converted to C
using F2C and modified to use more accurate sun / moon positions. The solid.f
program is based on an edited version of the dehanttideinelMJD.f source code
provided by Professor V. Dehant. This code is an implementation

I have a web page devoted to finding true North.

There are many ways. Here's on that uses the north star.

Hi Bryan:
The first data on tectonic plate movement came from the Latitude Observatories. The Longitude problem was solved fairly
quickly by Harrison's clocks but the uncertainty of an observatories latitude because of wobble of the pole took much
longer and was addressed by a hand full of Lat
