Sharpening an increment borer by Chhin Lab. A short how-to video on the proper techniques for sharpening an increment borer using an increment borer sharpening kit. It is not recommended that you over-sharpen your increment borer (this could make the bit brittle and prone to breaking), you should only sharpen it if it needs to be sharpened. Remember: Clean your increment borer frequently (using a gun cleaning kit) and apply WD-40 to preve.. 2016. 4. 8.

With help from the National Science Foundation, he uses Dendrochronology, or tree-ring dating, to get a snapshot of climate change over time. Stahle can also determine things like the socioeconomic impact of droughts... 2015. 9. 24. 2012, Ancient Trees Reveal Environmental Histories from Lamont Doherty Earth Observatory Ancient Trees Reveal Environmental Histories from Lamont Doherty on Vimeo. Evidence from old-growth trees and ancient timbers recovered from homes and barns in the eastern U.S. and Hudson Valley region suggests that the climate and ecology of the previous four centuries may not have been as temperate as once thought. Using dendrochronology, or tree ring analysis, researchers at Lamont-Doherty n.. 2015. 9. 24. 2013, Dendrochronology by Swiss Federal Institute for Forest, Snow and Landscape Research WSL Jahrringforschung Eidg.
