ICE-CORE LINKAGE CHARACTERISTICS

Both records show a shift to more negative ¹⁸O values within core segments that were deposited during the LIA. Second, both records show an increase in the small-scale variation in the ¹⁸O signal during the LIA. Third, both cores show an abrupt shift from the high amplitude isotopic variations during the LIA to much lower amplitude isotopic variations characteristic of post-LIA ice.
