Report on entrance to Port Phillip Bay

Port of Melbourne Corporation (PoMC) released, on 17 August 2006, a report on the most comprehensive scientific investigation ever conducted at the entrance to Port Phillip Bay.

The 180-page report by scientific organisation Australian Marine Ecology (AME) has provided the port with a vast amount of valuable scientific information as it prepares the key environmental reports for the proposed Channel Deepening Project.

One of the learnings from the trial dredge at the entrance in August 2005 was to look at how to reduce the amount of loose rock created in the dredging process. The AME study assessed the outcomes of rock fall after the trial dredge with extensive underwater field work, concluding in January 2006.

To aid in viewing and downloading the report, it has been divided into nine documents. The report may be downloaded from the links below.
