DESCRIPTION:
Allen et al. 1999 Lago Grande di Monticchio High Resolution Sediment Data.
Multi-proxy lacustrine sediments independantly dated by sedimentation rate 
based chronology corroborated by dated tephras. Linked to Mediterranean 
marine sediments dated by tephrochronology.

A series of four sediment cores (B, D, J and L) obtained from Lago Grande 
di Monticchio (40° 56' N, 15° 35' E, 656 m above sea level), a maar lake 
in Basilicata, southern Italy, extend to a depth of 72.5 m, and are 
independantly dated (sedimentation rate based chronology) to 102,000 years. 
Numerous vegetation changes were rapid, frequently occurring in less than 
200 years, showing that the terrestrial biosphere participated fully in 
last-glacial climate variability. Earlier than 65,000 years ago, the record 
shows more climate fluctuations than are apparent in the Greenland ice cores. 

Together, the multi-proxy data from the continental and marine records 
reveal differences in the seasonal character of climate during successive 
interstadials, and provide a step towards determining the underlying 
mechanisms of the centennial-millennial-scale variability.
