Another session within the Marine and Antarctic Research Strategy research theme : Innovation and engineering was chaired by Annie Bekker of the Sound and Vibration Group (SVG) at Stellenbosch university. This was an evening session done in a round table format and included international speakers from Finland.

Prof Werner Nel chaired the session on earth system Observations under the title: “Antarctic and sub-Antarctic Earth Science”. The session opened with a talk by Geoff Grantham of University of Johannesburg and Werner then introduced research Landscape and climate interactions in the sub-Antarctic. The session was in the format of a panel and roundtable discussion. (Above group photo of Landscape research in mountain and polar environments)

Dr Mia Wege chaired the session on Marine Mammals during the 6th SANAP Symposium that resorts within the Marine and Antarctic Research Strategy – ecosystems, biodiversity and biodiscovery. The session includes talks on various marine and the presentations were arranged according roughly to species and area. This Included elephant seals, fur seal, Ross seal, whales in ice, whales along the Southern African coast The session was presented in panel, discussion format, that allowed for questions form the audience.

It was great to see the Mammal Research Institute Whale Unit of the University of Pretoria based in Hermanus, Western Cape represented during the symposium by Dr Els Vermeulen, Matthew Germishuizen, Elisa Seyboth and Antonia Immerz. (Above L-R)
The Prince Edward Island scientific expedition was able to join the symposium on the 30th November and Chris Oosthuizen did his presentation in the session, ‘Data Management and the Summer Survey Participants’ chaired by Dr Christel Hansen. Liezel Pretorius was also able to join the conference on the Thursday. (Above L-R: Chris Oosthuizen, Liezel Pretorius, Yinhla Shihlomuhle)

An initiative by Mia Wege was to use the SANAP symposium to bring all “bio loggers/trackers” together, that included researchers who tag animals, mostly top predators across the globe. The purpose was to get some structure going and talk about a potential larger workshop specifically for the entire community. The meeting was well represented, and this was a great opportunity used.
Two of the Principal investigators of the project were able to attend the symposium. ( Nico de Bruyn(left) – University of Pretoria and Jaco Versfeld (Right) Stellenbosch University)
