Drought variability in the Pacific Northwest
from a 6,000-yr lake sediment record.
Proceedings of the National Academy of Sciences,
PNAS published ahead of print February 22, 2011,
doi:10.1073/pnas.1009194108.
We present a 6,000-yr record of changing water balance in the
Pacific Northwest inferred from measurements of carbonate d18O
and grayscale on a sediment core collected from Castor Lake,
Washington. This subdecadally resolved drought record tracks
the 1,500-yr tree-ring-based Palmer Drought Severity Index
reconstructions of Cook et al. [Cook ER, Woodhouse CA,
Eakin CM, Meko DM, Stahle DW (2004) Science 306:1015-1018]
in the Pacific Northwest and extends our knowledge back to
6,000 yr B.P. The results demonstrate that low-frequency
drought/pluvial cycles, with occasional long-duration,
multidecadal events, are a persistent feature of regional
climate. Furthermore, the average duration of multidecadal
wet/dry cycles has increased since the middle Holocene,
which has acted to increase the amplitude and impact of
these events. This is especially apparent during the last
1,000 yr. We suggest these transitions were driven by changes
in the tropical and extratropical Pacific and are related to
apparent intensification of the El Niño Southern Oscillation
over this interval and its related effects on the Pacific
Decadal Oscillation. The Castor Lake record also corroborates
the notion that the 20th century, prior to recent aridity,
was a relatively wet period compared to the last 6,000 yr.
Our findings suggest that the hydroclimate response in the
Pacific Northwest to future warming will be intimately tied
to the impact of warming on the El Niño Southern Oscillation.
STUDY NOTES: Sediment gray scale data for Castor Lake, Washington, USA,
providing a subdecadally resolved drought record for the
Pacific Northwest over the past 6,000 years.
