The associated NCEI study type is Tree Ring. The data include parameters of climate reconstructions|tree ring with a geographic location of British Columbia, Canada. The time period coverage is from 999 to -40 in calendar years before present (BP). See metadata information for parameter and study location details. Please cite this study when using the data. Tree ring data from the International Tree Ring Data Bank and World Data Center for Paleoclimatology archives. Most data sets include raw treering measurements (most are annual ring width, with some collections of earlywood or latewood width or wood density), plus chronologies (standardized growth indices for a site compiled from multiple treering samples). Reconstructions of climate variables are included with some of these data sets. Each data type is stored in a separate data file; the data type is coded into the file name.

Composite d13C and d18O chronologies spanning AD 951-1990 were developed from cross-dated 10-yr increments of Picea engelmannii (Engelmann spruce) and Pinus albicaulis (whitebark pine) collected from 16 subfossil snags and living-tree sequences at three sites near the Athabasca, Robson, and Bennington glaciers. Carbon-isotope analyses were performed on cellulose by closed-tube combustion followed by dual-inlet mass spectrometry. The d13C data were corrected for changing d13C of atmospheric CO2 post-1850. Cellulose oxygen-isotope data were obtained by high-temperature pyrolysis followed by CF-IRMS. Growth season RH and winter T were reconstructed using a coupled isotope response-surface approach. See Edwards et al. (2008) for full details. IITRDB12 ABSTRACT SUPPLIED BY ORIGINATOR: Modelling of tree-ring d13C and d18O data from the Columbia Icefield area in the eastern Rocky Mountains of western Canada provides fuller understanding of climatic and hydrologic variability over the past 1000 yr in this region, based on reconstruction of changes in growth season atmospheric relative humidity (RHgrs), winter temperature (Twin) and the precipitation d18O-Twin relation. The Little Ice Age (~AD 1530s-1890s) is marked by low RHgrs and Twin and a d18O-Twin relation offset from that of the present, reflecting enhanced meridional circulation and persistent influence of Arctic air masses. Independent proxy hydrologic evidence suggests that snowmelt sustained relatively abundant streamflow at this time in rivers draining the eastern Rockies. In contrast, the early millennium was marked by higher RHgrs and Twin and a d18O-Twin relation like that of the 20th century, consistent with pervasive influence of Pacific air masses because of strong zonal circulation. Especially mild conditions prevailed during the "Medieval Climate Anomaly" ~AD 1100-1250, corresponding with evidence for reduced discharge in rivers draining the eastern Rockies and extensive hydrological drought in neighbouring western USA.
