Seismic survey effects on whales and dolphins

The ocean is a noisy place, as, unlike light and other possible stimuli, sound can travel very efficiently in seawater. Anthropogenic noise pollution in the marine environment is becoming a large concern – underwater noise created by ships and other human-related sources can be detected many kilometres away, far beyond what would be seen or READ MORE

What is a seismic survey?

A seismic survey is a method of investigating the subterranean structure, primarily used in search of oil and gas deposits. Marine seismic surveys have been performed since the 1950s when chemical explosives were used to create sound waves. In the 1960s airguns were developed and are now currently used for almost all seismic surveys. Airguns READ MORE

Cape eelgrass

You’re slowly cruising along the Keurbooms River when the boat motor sputters and dies, and once you pull it up out of the water, there clogged in the propeller is a clump of Cape eelgrass or zostera grass Zostera capensis.

Each foot has READ MORE

SANCCOB saves seabirds

Over the past few months I have had the chance to spend some time volunteering at the SANCCOB facility in Cape St Francis. Unfortunately, of the 15 seabird species that breed in South Africa, over half have decreasing populations and have a threatened status according to IUCN. SANCCOB stands for South African Foundation for the READ MORE

The amazing African penguin

After having the amazing opportunity to work with African penguins at the Cape St Francis SANCCOB facility, I have a much greater appreciation for these incredible birds! African penguins stand 60-70 cm tall, and are built like a solid rugby player weighing in somewhere between 2.2-3.5 kg. They are beautiful birds, distinct with black backs READ MORE

Summer season and the snakes are slithering

With the summer season arriving and the weather warming up, you’ll find more people out and about, but you will also find the snakes of the region are becoming more active too! One of the species people most commonly mentioned are the “puffies” – the puff adders Bitis arietans. Puff adders have an extensive range, READ MORE

Sure footed rock rabbit

Robberg Nature Reserve has a host of interesting species to find and see. While some of these, like the caracal, are a rarer sighting, animals like the rock hyrax Procavia capensis are plentiful and you can often find one basking on a rock in the sunshine. Hyrax are more commonly known as dassies by South READ MORE
