The Australasian INTIMATE Project
OBJECTIVE:
•
Identify and prioritise Australian onshore and offshore reference records for
the OIS 2/1 transition.
•
Promote ways to effect high-precision and dating of key Australian onshore and
offshore records for the determination of a regional event stratigraphy.
Background
Since 1997, INTIMATE (INTegration
of Ice-core, Marine and TErrestrial records – a
core programme of the INQUA (International Union for Quaternary Research)
Palaeoclimate Commission) project members have, through a series of
international workshops, sought ways to improve procedures for establishing the
precise ages of, and effecting high-resolution correlations between North
Atlantic climate events of the Last Termination. There have been two major
driving forces behind this. First was the publication of the GRIP and GISP2
ice-core record (Alley et al. 1993; Johnsen et al.
2001), which showed that environmental changes during the Last Termination were
more abrupt and complex than had been previously been realised. They
demonstrated the need for methods that enabled the sequence of events during
the Last Termination to be reconstructed at the decadal time–scale. The
second was the growing realisation of the severity of the difficulties that
affect radiocarbon dates, the method most widely used to date the Last
Termination events. North Atlantic INTIMATE members have therefore proposed a
number of ways by which clarity and precision might be improved, and these
include an event stratigraphy basis for correlation (Bjorck
et al. 1998; Walker et al. 1999; Lowe et al. 2001), improved protocols for
radiocarbon dating (e.g. Wohlfarth 1996; Lowe and
Walker 2000) and tephrochronology (Turney et al.
2004), correlation based on stratigraphical methods
thought to reflect synchronous regional or global changes (e.g. oxygen isotope
stratigraphy; Hoek and Bohncke
2001) and more effective use of sites with annually laminated sediment
sequences (e.g. Litt et al. 2001).
