1,500 year quantitative reconstruction of winter precipitation
in the Pacific Northwest.

Multiple paleoclimate proxies are required for robust assessment
of past hydroclimatic conditions. Currently, estimates of drought
variability over the past several thousand years are based largely
on tree-ring records. We produced a 1,500-y record of winter
precipitation in the Pacific Northwest using a physical model-based
analysis of lake sediment oxygen isotope data. Our results indicate
that during the Medieval Climate Anomaly (MCA) (900-1300 AD)
the Pacific Northwest experienced exceptional wetness in winter
and that during the Little Ice Age (LIA) (1450-1850 AD) conditions
were drier, contrasting with hydroclimatic anomalies in the desert
Southwest and consistent with climate dynamics related to the El
Niño Southern Oscillation (ENSO) and the Pacific Decadal Oscillation
(PDO). These findings are somewhat discordant with drought records
from tree rings, suggesting that differences in seasonal sensitivity
between the two proxies allow a more complete understanding of the
climate system and likely explain disparities in inferred climate
trends over centennial timescales.
STUDY NOTES: Delta d180 data and 1500 year November-February precipitation reconstruction
from Castor Lake and Lime Lake, eastern Washington, USA, for the last 1500 years.
Castor and Lime Lakes are located east of the Cascade Range, in a relatively dry,
PDO/ENSO sensitive region. Results indicate that November-February rain/snowfall
is the strongest control on Castor Lake sediment d18O values and modeled Dd18O values.
Castor Lake: 48.54°N, 119.56°W, elevation 594 m, ~12m depth
Lime Lake: 48.87°N, 117.34°W, elevation 780 m, ~15m depth
Renner Lake: 48.78°N, 118.19°W, elevation 754 m
