The truth about marine noise pollution – the effect of anthropogenic sound in the sea

Marine Species, Overfishing, Pollution / By

Sound travels 4.8 times faster underwater than in air and in the sea frequencies below 1000 Hertz can transmit for thousands of kilometers. Sound is a form of energy that is manifest as a wave of changes in pressure. It can change in frequency, wavelength, and intensity. The nature of the medium through which sound moves (e.g., air or water), its temperature, and the pressure affects the speed and path of the wave.

It’s beyond time for the Faroese grindadráp hunts to stop

Marine Species, Overfishing / By

The grindadráp or grind, as it’s usually called, is a hunting method created by the Vikings over 1,000 years ago, which the Faroese have preserved as a part of their culture. This archaic tradition consists of driving entire pods of small cetaceans (mainly long-finned pilot whales, which belong to the dolphin family, and Atlantic white-sided dolphins) to shore, where they face a painful death.

Blue Planet Society is a global pressure group campaigning to protect the world’s ocean.
