Environmental predictors of Carcharodon carcharias presence at two popular beaches in False Bay, South Africa using acoustic telemetry

Author: Van Beuningen, Dave Date: 2018 By understanding when white sharks (Carcharodon carcharias) are likely to be at certain popular beaches, it is possible to predict when the risk of overlap between water users and white sharks is highest, and to convey this information to the ... Read more
The influence of environmental variables on white shark (carcharodon carcharias) sightings at False Bay beaches.

Author: Weltz, Kay Date: 2012 In response to an increase in shark attacks in the Western Cape over the last decade, a shark warning system called Shark Spotters that records white sharks (Carcharodon carcharias) in the surf zone was implemented in 2004 in Cape Town, South Africa. Read more
