2003), A 100-year record of North Pacific volcanism in an ice core from Eclipse Icefield
[1] A record of regionally significant volcanic eruptions in the North Pacific over the last century has been developed using a glaciochemical record from Eclipse Icefield, Yukon Territory, Canada. Tephrochronology of the Eclipse ice core provides positive identification of the 1907 Ksudach, Kamchat...

[1] A record of regionally significant volcanic eruptions in the North Pacific over the last century has been developed using a glaciochemical record from Eclipse Icefield, Yukon Territory, Canada.

Non-sea-salt SO 4 2À residuals above a robust spline and empirical orthogonal function (EOF) analysis were used to identify volcanic SO 4 2À signatures.
