Ice cores are valuable archives of past climate and environmental information, helping us better understand Earth's climate system. ​

I've been lucky enough to participate in a number of ice core projects, including:

WAIS Divide, West Antarctica (2009-2010)

Mt. Waddington, British Columbia, Canada (2010)

Roosevelt Island, Antarctica (2012-2013)

Taylor Glacier, Antarctica (2015-2016)
