Overview
INTIMATE (INTegration of Ice-core, Marine And
TerrEstrial records), a core programme of the INQUA (International Union for Quaternary Research) Paleoclimate Commission,
aims to establish a more
detailed knowledge of the nature, timing and regional to global extent of
climatic and environmental changes associated with the Last Termination (the end
of the Last Glaciation). Initiated in 1997 and facilitated through a series of
international workshops, the project strives for improved precision in
establishing the ages of, and effecting high resolution correlations between,
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 records (Alley et al. 1993;
Johnsen et al. 2001), which showed
that environmental changes during the Last Termination were more abrupt and more
complex than had previously been realized. This highlighted a need for methods
that enable the sequence of events during the Last Termination to be
reconstructed at a resolution of decades. The second was a growing realization
of the severity of problems affecting radiocarbon dates, the most widely used
method for dating Last Termination events. INTIMATE members have proposed a
number of mechanisms for advancing the state of knowledge.
These include an event stratigraphy approach for correlation (Bjorck et
al. 1998; Walker et al. 1999; Lowe
et al. 2001); improved protocols for
both 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. marine oxygen isotope (MIS) stratigraphy (Hoek
and Bohncke 2001), and more effective use of sites with annually laminated
sediment sequences (e.g. Litt et al.
2001).
Members of the NZ
paleoclimate community attended the inaugural NZ-INTIMATE workshop,
- identify key New Zealand onshore and offshore records for the Last Glacial Maximum (LGM) and the Last Glacial-Interglacial Transition (LGIT).
- promote ways to improve procedures for establishing precise ages of, and effecting high resolution correlations between, onshore and offshore New Zealand records.
The 46 attendees at the meeting were unanimously in favour of preparing a poster
summarizing New Zealand proxy climate records spanning the last 30,000 years,
emphasizing continuous records (e.g. cores) from a variety of latitudes and
elevations, supplemented with fragmentary records (e.g. glacial, fluvial, and
loessial deposits). The poster reflects work-in-progress that will be updated as
new data become available. The
poster is intended to assist comparison of the
