Shark Spotter

Can we use GIS to improve the Shark Spotters program?

Shark Spotters The Shark Spotters shark safety program began in 2004 as a Proudly South African solution to a surge in the number of shark sightings and shark bites that was occurring at the time.

Abalone are a large species of snail found in temperate water environments in several areas around the world. They occur in Kelp forests and rocky reefs and play a very important role in the marine ecosystem helping stabilize these marine habitats in terms of community structure. Large declines in Abalone populations are altering the coastlines around the Read more…

NEW Behavioural Research Project!

Examining the patterns of interactions between individuals in both single-species and mixed-species shoals, particularly in relation to group cohesion, polarisation, and information use, and how these differ with risk. In collaboration with Alicia Burns, Behavioural biologist at Taronga Conservation Society Australia and researchers at the University of Sydney, Australia, Cape RADD will be assisting with data collection for this fascinating fish behaviour study. Here’s some info about the research project: Background Despite the frequency with Read more…

Interpreting Shark Movement With Accelerometers

“How do I do that in R?”: Ethographer What’s an accelerometer? Next up in our series of tutorials is a revisiting of some ancient work that I conducted while earning a masters degree at the University of Cape Town. In this project I compared patterns of shark swimming behaviour that were observed visually, with observations generated by interpreting accelerometer signals. “What’s an accelerometer” you ask? Well you’ve probably got one in your pocket. An accelerometer Read more…

Estimating Kelp cover from LANDSAT imagery

Monitoring the distribution of kelp We love kelp here at Cape RADD, if you haven’t gotten that by now then I don’t know what you’re reading. I try to use the word kelp in a sentence at least once a day and I am pretty sure I’ve seen Jessie feed some to Mike before. Any way, kelp was previously thought to be an important sentinel species whose decline would be the start of the bad Read more…
