Australasian paleoclimate of the last 2k: Intercomparison of climate field reconstruction methodologies, modeling, & data synthesis approaches

Auckland, New Zealand
Workshop report
Working groups
Meeting Category

aus2k-logoThis workshop will be the fourth meeting of the PAGES Aus2k Working Group. It will build on the progress made by the Aus2k community and also produce several key products that will allow us to assess the current status of the project and develop strategic coordination of current and future research activities by the group.


Topic of workshop

The Australasian (Aus2k) Working Group is currently supporting the wider goals of the second phase of the Past Global Changes (PAGES) 2k initiative to undertake reconstructions of global climate fields for the last two millennia: PAGES 2k Network.

Recent efforts have seen an expansion of the Aus2k database to include non-annually resolved data, new data selection criteria, and critical evaluation of proxy archives using modern climate data for calibration. That effort has now opened new horizons for multi proxy synthesis techniques, the generation of new simulations of the last 2000 years using state-of-the-art climate models, and palaeoclimate data-model comparisons.

This workshop will focus on progress for key developments the Aus2k initiative, and will include overviews of:

1. Synthesis and comparison of annually and non-anually resolved palaeoclimate data within the Australasian region;

2. Results from projects focused on inter-comparison of climate field reconstructions undertaken as multi-institutional efforts; and

3. Comparison of climate reconstructions with paleoclimate model simulations.

The workshop also seeks to strengthen ties between the PAGES Aus2k and Ocean2k working groups (Ocean2k).

We invite interested researchers to submit an abstract for inclusion in this workshop. There will  be a poster session to accommodate a range of research.

Confirmed speakers include

Mandy Freund: Progress on developing a temperature spatial field reconstruction for Australia over the past millennium 

Steven Phipps: Reconstruction of climate fields for the Australasian region using data assimilation

Drew Lorrey: Multiproxy climate reconstruction for the South Pacific and Southern Hemisphere from a New Zealand perspective 

Nerilie Abram: Comparison of coral, speleothem and ice core records from Australasia and Antarctica 

Bronwyn Dixon: Spatial and temporal coverage of archives of climate and environmental change in Australia

Ben Henley: A Pacific-basin wide reconstruction of the Interdecadal Pacific Oscillation

Duncan Ackerley: New, high-resolution simulations of the past 2000 years conducted using the ACCESS climate system model

Helen McGregor: A global synthesis of low-resolution SST reconstructions spanning the past 2000 years

Paul Augustinus:  High-resolution maar crater records of Auckland

Marcus Vandergoes: The Lake Ohau palaeoclimate reconstruction project

Publication opportunity

A special issue of Climate of the Past collating the research from this workshop is anticipated, with the prospect that several papers may be asked to join the global PAGES 2k special issue of Climate of the Past in 2016.
