Yakutat Moraines, Alaska - ak121 Additional Site Information David Barclay Tim Van Loan Gordon Jacoby Purpose of Collection: Geomorphology/Geology - glaciology Detrending: Smoothing spline fixed N cutoff Cores Stored at: Geology Department, SUNY Cortland, Cortland NY USA Reference: Barclay, D.J., J.L. Barclay, P.E. Calkin, and G.C. Wiles. 2006 A revised and extended Holocene glacial history of Icy Bay, southern Alaska, U.S.A. Arctic, Antarctic and Alpine Research, v.38, p.153-162. NOTES: This living tree chronology was collected to crossdate with glacially killed logs at Icy Bay, ~100 km to the west. Trees were growing on moraines and proximal outwash at Ophir Creek (OPH) and Sawmill and Redfield coves (YBM). Series were detrended with 32-year splines. Work was funded by the U.S. NSF under grant No. OPP-9321213. COFECHA output: Chronology file name : AK121.CRN Measurement file name : AK121.RWL Date checked : 18JUL12 Checked by : B.
