1. Almagre Hard(ly) Work
BRISTLECONE PINE RING WIDTHS ARE KEY "PROXIES" used to estimate temperature for the past 1000 years. But these essential records haven't been updated in decades. Prominent climate scientist Michael Mann (http://www.realclimate.org/index.php?p=11#comment-345) said: "While paleoclimatologists are attempting to update many important proxy records to the present, THIS IS A COSTLY, AND LABOR-INTENSIVE ACTIVITY, OFTEN REQUIRING EXPENSIVE FIELD CAMPAIGNS that involve traveling with heavy equipment to difficult-to-reach locations (such as high-elevation or remote polar sites)." OUR SOLUTION: Summer '07, a volunteer interdisciplinary team was formed, to update and extend the Mount Almagre bristlecone data collected by Donald Graybill in 1984. Under a U.S. Forest Service permit, we collected 64 cores from 48 trees in 3 days. On the third day, we located 17 trees with Graybill tags, of which 9 were re-sampled.
HOW HARD WAS IT, REALLY? This album answers that first question everyone's asking.
