Research Co-ordinator

On the 21st of June we received a call about a dead dolphin stranded at 2nd beach, along Die Plaat. We promptly got all our stranding gear together measuring tape, knives, clipboards, data sheets and sampling equipment, and as soon as the volunteers returned from their shark cage diving trip we all hopped into the International Marine Volunteers (IMV) Samil and headed down to the coast.

Deployment Success

June 25, 2015 by dyertrust

By Alison Towner, DICT.

On Thursday the 11th of June, our team, including our International Marine Volunteers, launched to deploy phase one of our acoustic receivers. This work forms an integral component of my PhD research on white shark behavioral ecology and habitat use in the Gansbaai region. We began the expedition by retrieving and replacing the line of receivers previously deployed outside Dyer Island. Dr Rhett Bennett from the South African Institute of Aquatic Biodiversity (SAIAB) joined us, and as the receivers each have acoustic releases no diving was required. (Also see Dyer Island Acoustic Receiver Roll Over, DICT Deploy Vemco VR2 Listening Stations). Each ATAP listening station surfaced within 6 minutes, with very little bio-fouling. We were lucky as the process can take hours and stations can sometimes become severely fouled! We were able to re-deploy new stations again within an hour! Once completed, we moved off to several other sites around Gansbaai and Dyer Island to drop the first phase of receivers for the white shark passive tracking project. Each deployment site was carefully selected, to provide optimal acoustic tag coverage, based on our previous manual tracking data and our combined skippers extensive knowledge of white shark hotspots. It is also imperative that we selected safe depths for the receivers, given the relentless nature of the Cape of Storms!
