6th SANAP Symposium Reflections: Human Enterprise

6th SANAP Symposium Reflections: Human Enterprise

The only session on human enterprise within the Marine and Antarctic Research Strategy research themes was chaired by Charne Lavery. These presentations include humanities within the South African National Antarctic Programme. Four higher education institutions; University of Pretoria, University of Cape Town, Stellenbosch University and University of the Free State, were involved and the presentations were of a wide variety.

Jean Brundrit : “Over the Horison” was displayed with other publications by the Antarctic Legacy of South Africa.

Charne added fiction titles to everyone’s reading lists.

Alistair Mackay:  It Doesn’t Have to Be This Way. “The high-tide mark is Strand Street again, just as it was before the land reclamations of the twentieth century. The waves break on the outer stone walls of the seventeenth-century Dutch Fortress, but the water is only ankle-deep along the street. He walks along the breakers in the cool ocean spray. Waves smash into foreshore skyscrapers. They ricochet off the buildings and form mesmerizing patterns as they funnel towards him over Long Street, then Adderley Street.”

Peter Wilhelm:  Summer’s End.This is a tale of South Africa in the next Ice Age. Imagine the vast desolation and beauty of Antarctica massed up against the southern mountains. To the north the highveld will be covered in permanent snow and ice. Terrifying storms will sweep across the plains between. Here our descendants will live, clinging to their humanity.”

6th SANAP Symposium Reflections: Ecosystems, Biodiscovery and Biosecurity – Ornithology

The last session within the Marine and Antarctic Research Strategy research theme :  : Ecosystems, biodiversity and biodiscovery was chaired  by Pierre Pistorius of the Marine Apex Predator Research Unit (MAPRU) at Nelson Mandela University.  To kick off the session, the Mouse-Free Marion (MFM) Project’s Assistant Project Manager, Sue Tonin, gave a plenary lecture. This was followed by more presentations on ornithology research. (Above: group photo of  MAPRU with Sue Tonin. Left: Pierre Pistorius. Right: Sue Tonin)
