Blue Intensity for Dendroclimatology: The BC Blues: A Case Study from British Columbia Canada. The Holocene. 24 (11): 1428-1438. NOTES: Aspect: SE/E Slope Angle: 10-25 Estimated Species Composition: 85% SF, 15% ES ES = Engelmann spruce; SF = Sub-alpine fir; WP = Whitebark pine; AL = Alpine larch; C = Western red cedar; MH = Mountain hemlock; LP = Lodgepole pine Site Information: Old trees recognised by thin crown. Dry site Data collection updated 2016-02-10 to add Blue Intensity data, file cana234b.rwl. The Blue Intensity data were measured almost exactly from the same samples as the MXD data, although BI may not have been measured from all the samples due to discolouration issues. See Wilson et al. 2014 and Rydval et al. 2014 for additional information. BI measurment method As spruce does not express an obvious visible colour difference between the heartwood and sapwood, no pre-treatment (i.e. resin extraction) of the samples was made and the mounted cores were simply sanded up to 1200 grit grade. Residual wood dust was removed using compressed air. The scanner was calibrated using the SilverFast Auto IT8 Calibration procedure to the IT8 Calibration Target (IT8.7/2) printed on Kodak Professional Endura paper. All samples were scanned to 2400 DPI with the scanner covered by a box to minimise bias from external ambient light. The digital image of each sample was then imported into CooRecorder and the ring-boundaries marked and visually crossdated. BI data were then generated using frame dimensions (160-5-50-15) derived from experimentation with Scots pine (Rydval et al., 2014). The archived BI data are RAW measurments and have not been inverted. Rydval, M, Larsson, L-A, McGlynn, L, Gunnarson, BE, Loader, NJ, Young, GHF and Wilson, R. 2014.
