The WWF call for regulation to decrease underwater noise pollution

  Until recently, most Arctic waters were home to naturally occurring sounds that marine life could interpret and rely upon for activities like feeding, mating, communicating and navigating. But as the climate crisis continues to warm temperatures and melt sea ice, the Arctic Ocean is increasingly affected by underwater noise from intensifying rates of shipping, … Continued

Momentous Developments in Ocean Protection

2023 has seen momentous developments in Ocean protection. For the first time in 9 years, the International Maritime Organisation (IMO) has updated its guidelines to reduce underwater noise from shipping; the EU has announced an €816.5 million commitment; and the UN are well underway to sign a High Sea Treaty to protect a third of … Continued

The pressure is on to reduce Underwater Radiated Noise (URN) from ship propellers

A propeller technology capable of substantially reducing the underwater radiated noise (URN) generated by ships’ propellers has been developed by Oscar Propulsion Limited and the University of Strathclyde. The patented PressurePores™ system reduces propeller tip vortex cavitation by applying a small number of strategically placed holes in the propeller blades. The addition of these pressure-relieving … Continued
