The two “lost” Graumlich foxtail series used in Esper et al 2002 were archived today at WDCP. Only the specific series that I had requested were archived; other series in Bunn et al 2005 were not archived – see prior discussion here.
UPDATE May 17: Graumlich also archived two chronologies (Boreal -ca636.crn; Upper Wright – ca637.crn). I’ve plotted these chronologies against the chronologies emailed to me by Science in February. There is also a slight difference in the number of cores used in each. For Boreal, Esper shows 64 cores as being used to make his chronology, while Graumlich has only archived 63 cores. For Upper Wright, Graumlich has 77 cores starting after 710 (the start of the Esper series), while Esper says that he used 78 cores. These numbers in Esper appear to be computer-generated rather than misprints, so there seems to be some remaining slight difference between the data as used by Esper and as archived by Graumlich.
