Plan to expand Onslow Marine Support Base given the tick of approval by Environmental Protection Authority after proponent incorporates dredging science from the Western Australian Marine Science Institution.
A proposal to extend the Onslow Marine Support Base to allow off-shore vessels to access the newly constructed Beadon Creek Maritime Facility was recommended for environmental approval by the Western Australian Environmental Protection Authority.
The end-of-program 2017 Dredging Science Node Conference brings together the results of one of Australia’s largest and most successful single issue marine research programs.

Research has confirmed that some coral and important reef building algae can sustain being exposed to low light conditions for up to 10 consecutive days before their health is critically affected.
Researchers working to predict the environmental impacts associated with dredging have found that branching corals are highly adept at cleaning their surfaces of depositing sediments compared to other coral structures.
New research has defined a series of thresholds that can be used to reliably predict the impact of water quality levels on coral health.
Further research into dredging pressures on coral has revealed that even a very fine layer of sediment can prevent coral larvae from settling on a surface and building on the coral community.
Sponges can alleviate pressure from sediments in the short-term, but researchers have found that longer-term exposure may still compromise fitness.
