Dr Nick Mortimer, GNS Science
2015 Hochstetter Lecture and the RSNZ Manawatu September 2015 meeting – joint with the Geoscience Society of New Zealand
7.30 pm Tuesday, 15 September, Te Manawa – Art Gallery, 326 Main Street, Palmerston North
Continents are the largest solid objects on the Earth’s surface. In this illustrated talk Nick will summarise the scientific case that there are not seven but eight continents: Africa, Antarctica, Asia, Australia, Europe, North America, South America and Zealandia. Although Zealandia is 4.9 million square kilometres in area, it has literally lain hidden because 94% of it is under the sea. In the talk Nick will also speak about how Zealandia became the world’s most submerged continent and why its continental identity is important to science and to society.
Nick Mortimer is a geologist at the Dunedin office of the Crown Research Institute GNS Science. In his 26 year career he has carried out land- and ship-based field work throughout the length and breadth of New Zealand and Zealandia. He recently co-authored a Penguin book on Zealandia with his colleague Hamish Campbell.
All warmly welcome
