Seismic surveys – the full story?

Humans have moved into all areas of the world, and even if they are not present, evidence of them is. The marine environment is no different. Marine litter has been of foremost concern but there is growing interest and concern over anthropogenic noise in the marine environment. Seismic surveys, shipping, high power sonar, and echo […]

When one thinks about sound in a marine environment, the clicks and squeals of dolphins, and long songs of the whales comes first to mind. So it would seem logical to think that the acoustic signal from a seismic survey array affects primarily dolphins and whales. While much concern has been over the wellbeing of […]

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 […]

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 […]

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 […]
