Strong cross-dating # among ring-width series from sites up to 60 km apart and an analysis of # sample homogeneity support combination of all samples into a single, # regional composite chronology. Comparison with instrumental climate data # indicates May through July temperatures of the growth year are the primary # control on ring-widths. Multidecadal-length warm periods in western Prince # William Sound during the past 800 years were centred on AD 1300, 1440 and # possibly 1820. Multidecadal-length cool periods were centred on AD 1400, # 1660 and 1870. This is the first tree-ring chronology from the Gulf of # Alaska region to extend into the first millennium AD. #------------------- # Site Information # Site_Name: Prince William Sound # Northernmost_Latitude: 60.45 # Southernmost_Latitude 60.45 # Easternmost_Longitude: -148.33 # Westernmost_Longitude: -148.33 # Elevation: 100 #------------------- # Data Collection # Collection_Name: NAm-TR_2-ak094-1200-1987 # First_Year: 1200 # Last_Year: 1987 # Time_Unit: AD # Notes: PAGES ID: NAm-TR_2; Correlation with Temperature: positive #------------------- # Species # Species_Name: Tsuga mertensiana (Bong.)
