Finishing Our Field Work



In this latest audio dispatch, I describe the end of our field work here–taking down our camp and setting our devices so they continue to collect data for us for the next two years.

  1. I am wondering if anyone is looking at the deuterium/hydrogen ratio profile in polar water, ice, minerals, bird feathers, etc. to see if there are any historic changes or trends. I recently read how the U.S. Geological Survey mapped D/H ratios in migratory birds and found some correlations with latitude. My own hypothesis is that D/H ratios are caused by astronomical phenomena which become fixed in organic and mineral processes.
