Changes in mid-troposphere snow accumulation on Mt. Logan, Yukon, over the last three centuries

EXTRACT (SEE PDF FOR FULL ABSTRACT): A net snow accumulation time series is presented. It is derived from a 102.5 m ice core retrieved from Mt. Logan at an altitude of 5340 m a.s.l. Annual increments are identified using stable isotopes, trace chemistry, and beta activity. ... The resulting time series of nearly 300 years seems to indicate a lower mean accumulation from AD 1700 to the mid-19th century than after that time. The last 100 years of the series correlates significantly with certain instrumental station records at mid-northern latitudes.

Paleorecords of interdecadal variability from mid-latitude varved sediments and tropical corals of the eastern Pacific [abstract]

EXTRACT (SEE PDF FOR FULL ABSTRACT): Reconstruction of proxy variables from massive corals and varved sediments of the eastern Pacific allow us to compare variability in the ocean climate from equatorial and mid-latitude sites for a significantly longer period than is available from the instrumental record.
