Some images from absolutely stuning field work with new MS student Tori Kennedy outside Atlin, British Columbia. Tori will be working on understanding the Holocene extent of glaciers here and all along the American Cordillera.
New paper summarizing our efforts in the northern Ross Sea! A little old, but hey we made the cover of American Journal of Science.
In a banner month, we’ve had two papers accepted in The Cryosphere bearing on the thickness of the West Antarctic ice sheet draining into the Weddell Sea embayment. One by Keir Nichols and the other by Perry Spector of Berkeley Geochronology Center. Final publication will be available online soon! In the mean time, since it is an open discussion format journal, which by the way are great to publish in, can be found here.
See our recent work on preparing quartz separates for measurement of in situ 14C and the importance of adequate leaching to remove 14C introduced during froth flotation of feldspars and other minerals. Published in the new EGU journal Geochronology
See our recent work published in Nuclear Instruments and Methods summarizing our in situ carbon-14 extraction system and its performance. Since we wrote this paper, we have measured more than 100 additional samples from all over the world.
The Tulane cosmogenic nuclide lab is proud to be part of the US-UK International Thwaites Glacier Collaboration. Eight projects will be investigating Thwaites Glacier and the surrounding region from all avenues and both present and past in order to better understand its possible future. The Tulane lab will be part of the Geologic History Constraints team where we will be drilling through Thwaites Glacier to collect subglacial bedrock to see if and when Thwaites Glacier was smaller than today and if so, how did it regrow. Check out our project webpage and the larger ITGC webpage!

See recently published work by Chris Darvill exploring the geological feasibility of a coastal route into the Americas from Beringia. Chris worked on refining the glacial history of coastal British Columbia.
See our recent work published in Earth and Planetary Science Letters on approaches to calibrating production rates.
We just published in Science the culmination of nearly nearly 10 years of work in western Canada on the demise of the Cordilleran Ice Sheet and its response to climate fluctuations at the end of the Last Glacial Maximum. See the great perspective piece by my colleagues and friends Shaun Marcott and Jeremy Shakun in regards to our recent work.
