We would like to thank Antarctica New Zealand staff based in Christchurch and Scott Base for their enthusiastic and innovative support with our project, especially Lou Sanson, Dean Peterson, Paul Woodgate, Julian Tangaere, Keith Springer, and John Roberts. We are grateful for the professional assistance of Ewan Paterson in the field. The crevasse safety training with Rob McBrearty was highly appreciated. We are indebted to Helicopter NZ staff, Rob McPhail and Richard Desborough. This project is funded by Victoria University of Wellington, FrST and the Trans-Antarctic Association Fund.
