Overview

This project will involve paleomagnetic techniques and/or organic geochemical techniques. Rising ocean temperatures may soon destabilise the West Antarctic Ice Sheet, which will result in sea-level rise and changes in oceanic and atmospheric circulation that will have a profound impact on New Zealand.

The Ross Ice Shelf protects the West Antarctic Ice Sheet from the warming ocean. Because little is known about past Ross Ice Shelf behaviour predictions of its future stability are challenging.

The project will help reconstruct the Ross Ice Shelf history since the last ice age, and the oceanographic changes which forced the ice to retreat.
