For a basic intro to ice cores, go to the excellent antarcticglaciers.org.
(A website and public resource managed by the talented Bethan Davies)

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)
