   EXECUTIVE SUMMARY:   
   - While we know there is a seasonal link between atm N2O and UFO   
     sightings, we have only previously speculated that the N2O may be   
     related to "farming activities" as N2O is related to e.g. ocean   
     plankton.  (We ignore the trend in N2O related to human farming and   
     the related rapid population growth).   
   - Here we measure ocean chlorophyll directly via ~200 ocean-going   
     robots operating across the Southern Ocean. It's found UFO activity   
     across N Am -ve correlates with seasonal chlorophyll.   
   - Breaking down UFO sightings by location, time-of-day, color and   
     shape we find some interesting patterns that post facto make sense.   
   - We recall the seasonal pattern of atm N2O is robustly linked with the   
     position of Saturn in its orbit and a provable 30y cycle is found in   
     modern measurements of N2O as well as other measurements extracted   
     from polar ice going back 800ky.   
      
      
   We've seen before there seem to be strong links between UFO sightings   
   across N Am (I use the NUFORC database) and levels of atm N2O around   
   the world.   
      
   N2O levels have been boosted in the past century by human activities   
   like industrial farming but the "background" cycle involves the   
   seasonal growth and decline of phytoplankton.   
      
   Looking at the almost 1 mn years of N2O data recovered from gas   
   bubbles trapped in ice at the poles we find there has been a clear   
   30-y cycle at least up until the last 300y when atm levels of the gas   
   "took off".   
      
   And we also find the position of the planet Saturn -- that has a   
   roughly 30y orbit around the sun -- correlates quite strongly with atm   
   N2O even over the last ~100y when human inputs ostensibly flooded the   
   seasonal cycle related to ocean plankton.   
      
   In this study we look at actual direct measurement of plankton in the   
   Southern Ocean. And no surprise what we find.   
      
   Over the last ~15y an increasing army of robots has been patrolling   
   the world's oceans. In the Southern Ocean about 200 robots currently   
   measure a long list of physical and biological values and transmit   
   them back to various groups to analyze. Some robots are "floats" and   
   strictly limited to surface measurements. But an increasing number are   
   "divers" that can cycle between the surface and the deep oceans --   
   down to 4km or more -- over days or weeks, making periodic   
   measurements.   
      
   One of the measurements available are estimates of chlorophyll   
   concentration -- a more or less direct marker for phytoplankton and   
   other ocean-based plants.   
      
   If it is the case that some chunk of UFO's represent "people" farming   
   the world's oceans then we would expect not only a correlation between   
   sightings and atm N2O levels but sightings and actual ocean   
   concentrations of chlorophyll.   
      
   The data from the ocean robots between roughly lat 25S and 70S (some   
   regions around the Antarctic Peninsula get closer to the S pole than   
   the average lat of the continent around 60S) shows a robust   
   correlation with sightings across the US and also Canada (a dataset   
   largely independent of the NUFORC database).  Both overall   
   correlations (\beta's) are -ve. Indicating when phytoplankton   
   increase in the Southern Ocean UFO sightings across N Am generally   
   decline. When the plankton are running -- there is a major peak and 2   
   minor peaks each year -- a significant fraction of UFO's seem to clear   
   the skies over N America and hang out somewhere else.   
      
   We can further break down at least the US sightings by object shape,   
   color, and time-of-day and find overall the same pattern is seen, but   
   there is some variation by object type. Ocean chlorophyll "explains" a   
   good fraction of sightings, but by no means a majority.  But we   
   suspect sightings anyway are "mostly" mistakes or hoaxes and don't   
   represent anything very interesting. We don't expect large R2 values   
   ("explanation power").   
      
   The summary table for the robust links follow. It should be noted we   
   can statistically test whether there is probably "no relationship"   
   between a type of UFO and ocean chlorophyll (phytoplankton) and if we   
   do this we get the somewhat startling result that no group of objects   
   has a probably "zero correlation". While some types make be strongly   
   connected -- my s/w uses 2 independent test that between them should   
   prove a connection with an error between 1 in 1000 ("3 9s") and 1 in   
   10000 ("4 9s") -- it seems all types have some link, possibly by   
   indirect "knock on effects" possibly, of course, including the   
   behavior of the people doing the UFO sighting. Plankton as noted has a   
   seasonal behaviour.  So do people.   
      
   The table is thus:

   We see most groups have the expected -ve corr against ocean   
   chlorophyll.  Interesting exceptions are "dusk" UFOs -- sighted in the   
   hr before to the hr after local sundown and "dawn" -- the hr before to   
   the hr after local sunrise. We find the "daytime" sightings are not   
   provably correlated with sightings while the "nighttime" sightings are   
   -ve correlated.   
      
   It seems dawn and dusk are "transition times" between daytime (when   
   sightings don't correlate one way or another with chlorophyll) and   
   nighttime when the corr is -ve.   
      
   There is another interesting pattern based on location (US state) of   
   sighting.  Alaska sees a +ve corr while other states have a -ve corr   
   with chlorophyll.  We might speculate that Alaska is similar to the   
   Southern Ocean the location of blooms of phytoplankton and a   
   "destination location" for interested objects, while states like NJ   
   and NY are "source locations" of the relevant movement and would see a
