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
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
