Dragging the Chain

The Project

Dragging the ChainThis project will examine the effect of deep-water anchors on the seabed of Australia’s east coast. Deep-water vessels are essential to the nation’s trade links; more than 11,000 vessels visit Australian ports annually, supporting an industry worth $200 billion every year. This project aims to consider how these ships, which can have anchor chains up to a 100 metres in length, impact upon the ocean floor at popular ports. 

Researcher Allison Broad said the project would map the sea floor along the strip where the deep-water ships anchor at Port Kembla, approximately three nautical miles off shore, to investigate the impact on the environment and marine life. By using swath mapping, underwater video and 3D imagery, the researchers navigate the challenging underwater environment with the findings to then be disseminated to coastal zone managers.

 The innovative technologies will help the researchers to navigate the challenging underwater environment with the information to then be disseminated to coastal zone managers.

 “We’re bringing together government, both state and federal, and environmental agencies to examine the practices of the deep-water vessels,” Ms Broad said.

“We will look at how many ships are anchored offshore and how much damage is being done. A lot of marine life passes through this area. 

“We will test the biodiversity in the areas that have been impacted versus the non-impacted area. The aim is to ensure the sustainable use and development of this coastal zone.” 

Ms Broad said the project would have implications for coastal zones around the world, in both tropical and temperate climates, and would allow the University of Wollongong to position itself as a world leader in sustaining marine environments.
