Investigating the Pathways of Marine Debris Found in the Arafura and Timor Seas David Griffin, CAWCR Ilse Kiessling, DEWHA 29 July 2008

Pathways of Marine Debris Marine debris – not easy to clean up

Pathways of Marine Debris Many thousands of tonnes of nets

Pathways of Marine Debris not just ugly

Pathways of Marine Debris

high concentrations: northern Gulf of Carpentaria

Pathways of Marine Debris White (2004) hypothesis

Pathways of Marine Debris Bluelink Reanalysis: 0-10m, daily velocity average, release items for 1 year, follow them for another year

Pathways of Marine Debris

Add wind*3% to 0-10m, daily average current

Pathways of Marine Debris

Feb 0-10m

Pathways of Marine Debris May 0-10m

Pathways of Marine Debris Aug 0-10m

Pathways of Marine Debris Nov 0-10m

Pathways of Marine Debris

Conclusions Do nets move at the 0-10m velocity? If so, the model suggests they must come from the Pacific. But few nets are found on the Great Barrier Reef probable explanation: the model has too much flow through Torres

Pathways of Marine Debris Recommended future work include effect of tides on bottom drag determine drift characteristics of derelict nets validate model by releasing drifters in Arafura Sea
