EXECUTIVE SUMMARY:
- In the on-going hunt for (remote) locations with a strong connection
 with observed UFO activity, we look at daily sea surface
 temperatures correlated against daily UFO sightings.
- All major strong correlations lay in the S Hem in approx the 40S
 band.  The strongest responses are found in a region around Easter Is.
- The only significant response from the N Hem is "Atlantis" -- a
 point equi-distant from N Am, Europe and Greenland.
- On the Antarctic coast the only significant response is a volcanic
 coastal region so remote it remains unclaimed by any country.

I've updated the plots to include several interesting types of UFO.
The plots show possible "home addresses" for Disks, Ghost Missiles,
Spheres, Triangles, and Lights.

Some of the distibutions are obviously pretty extensive -- i.e. changes in 
daily ocean surface temperature in a large variety of areas of the world 
somehow predict how many UFO's will be reported across the US some days later.

Given the strength of the relationships -- R2's up to 90% -- the diversity 
of UFO types and ocean locations they can't all be about the weather.
