Determining Patterns of Abrupt Climate Change during the Last Glacial-Interglacial Transition (LGIT) in the Southern Hemisphere
This proposal will fund the development of a continuous, isotopically-dated paleochironomid and pollen record of deglacial climate fluctuations from lake sediments located in climatically sensitive sites along the Southern Alps, New Zealand. Detailed investigations will be carried out for the Last G...

This proposal will fund the development of a continuous, isotopically-dated paleochironomid and pollen record of deglacial climate fluctuations from lake sediments located in climatically sensitive sites along the Southern Alps, New Zealand.

The primary scientific objectives of the project are to determine: 1) the pattern and magnitude of past climate change; 2) whether changes recorded show an in-phase or out-of-phase relationship with the Northern Hemisphere; and 3) whether the Antarctic signature extends into the southwest Pacific region.
