The Paleoclimate Modelling Intercomparison
Project (PMIP3) now includes the 8.2 ka event as a test
of model sensitivity to North Atlantic freshwater forcing.
To provide benchmarks for intercomparison, we compiled
and analyzed high-resolution records spanning this event.
Two previously-described anomaly patterns that emerge are
cooling around the North Atlantic and drier conditions in
the Northern Hemisphere tropics. Newer to this compilation
are more robustly-deļ¬ned wetter conditions in the Southern Hemisphere tropics and regionally-limited warming in
the Southern Hemisphere. Most anomalies around the globe
lasted on the order of 100 to 150 yr. More quantitative reconstructions are now available and indicate cooling of ~1C and a ~20% decrease in precipitation in parts of Europe as
well as spatial gradients in d18O from the high to low latitudes. Unresolved questions remain about the seasonality of
the climate response to freshwater forcing and the extent to
which the bipolar seesaw operated in the early Holocene.
STUDY NOTES: This compilation of proxy records includes quality-controlled values from cores spanning part or all
of the period between 7,400 and 9,000 calendar years before present, provided on a common age scale
(calendar years before present, where present = 1950 A.D.). The main data file is in comma-separated
values format and first gives metadata information for each of the cores (i.e., site name, variable
measured, latitude, longitude, journal citation). Below the metadata, data for all time series are
presented in three columns. The first column is a Time series Index, which identifies the time series
according to the metadata table; the second column is age in calendar years BP; and the third column
is the proxy timeseries values. Since this data set only spans a period near 8,200 calendar years
before present, these are often subsets of a core's full data. All data from a core as well as chronology
to FTP files are listed below
in the "File URL" column.
