New Zealander Peter Barrett discovered the first tetrapod remains in Antarctica in 1967. Subsequent research that identified the remains provided the first evidence that land vertebrates had roamed Antarctica when its climate was warm, and lent support to the then controversial theories of continental drift and Gondwanaland. But Barrett's contribution to Antarctic science goes beyond his 'serendipitous discovery' as a doctoral student. He has also been acknowledged as the 'supremo' of the geological drilling community in the Antarctic for his work in this area from the 1970s onwards.

These early projects eventually led to the multi-national Cape Roberts Project, headed by Barrett, now the director of the Antarctic Research Centre at Victoria University. During the late 1990s, three holes drilled near the edge of the mountains recovered a remarkable 'sedimentary tape recorder', confirming that massive ice sheets have covered Antarctica since around 34 million years ago. However, the ice cover was highly dynamic, coming and going in response to perturbations in the Earth's orbit, known as Milankovitch cycles, which affect the amount of radiation the planet receives. For the past 15 million years, the size of the ice cap has been relatively stable.
