  • Maps of vessel density 2013-2015 for AIS-equipped vessels, in terms of km traversed in each cell for range of vessel classes for the Australian EZ. AIS data was sourced from AMSA and subsequently processed. The density was calculated for subsets of vessels based on various characteristics such as size or vessel use/purpose. These characteristics were derived and may contain errors. See Peel et. al. (2018) for detail on the processing methods.

  • The relative vessel strike risk for various species (humpback whale, green turtle, dugong, seagrass locations and generic species) and selected vessel categories over the 3 year period 2013-2015. Risk is calculated from available animal distribution information ([1][2][3][4][5][6]) and vessel Automatic Information System (AIS) data (supplied by AMSA [7]). From this, two risk metrics are derived: 1) relative risk of a collision, and 2) for large whales (humpback, sperm, southern right whale): vessel speed vs mortality curves are used to obtain relative risk of a fatal collision. A more detailed description of the underlying data and the risk metrics used is given in [8].

  • This data is a combination of records held by the Australian Maritime Safety Authority. From 1999 to 2011 Australia shipping was tracked through the Australian Ship Reporting System (AUSREP). From 2012 onward this changed to the Automatic Identification System (AIS). The data presented here are summaries of the tracks of vessels between the points identified by either AUSREP or AIS, summarised to the number of KM per 0.1 deg grid square. The AIS is a Very High Frequency (VHF) radio broadcasting system which enables AIS equipped vessels and shore-based stations to send and receive identifying information. This information can: be displayed on a computer or chart plotter aid in situational awareness provide a means to assist in collision avoidance. The International Maritime Organization (IMO) defines AIS as a ship and shore based broadcast system, operating in the VHF maritime band. The AIS can handle over 2,000 reports per minute and may update information as often as every two seconds. https://www.amsa.gov.au/navigation/services/ais/ Australian Ship Reporting System (AUSREP) is a ship reporting system designed to contribute to the safety of life at sea and is operated by the Australian Maritime Safety Authority (AMSA) through the Australian Rescue Coordination Centre (RCC Australia) in Canberra. Participation in AUSREP is mandatory for certain ships but most other commercial ships participate voluntarily. Shipmasters send a position report each day at a convenient time nominated by the ship, the maximum time between any two reports is not to exceed 24 hours. The data is used as reference material only, designed to indicate shipping lanes and the number of vessels moving through Australian waters. AUSREP commenced in 1973 in line with Australia's obligations under the International Convention for the Safety of Life at Sea (SOLAS) as a ship reporting system and is operated by AMSA through the RCC Australia in Canberra. https://www.operations.amsa.gov.au/Spatial/DataServices/MapProduct

    In 1991, CSIRO was approached to design and manage an environmental study of the Bay to seek answers to questions concerning the sustainable use and management of the Bay. The Study began in October 1992 and finished in June 1996. The Port Phillip Bay Environmental Study was managed by CSIRO and supervised by a Management Committee chaired by the (then) Department of Conservation and Natural Resources. Also represented on the committee were the EPA, Melbourne Water, Melbourne Parks and Waterways and the former Port of Melbourne Authority. The Study was totally funded by Melbourne Water and Melbourne Parks and Waterways. In all, some 47 research tasks were conducted, ranging from scientific literature reviews to fullscale field surveys. All were contracted out. Of the 30 contractors, six were Victorian State agencies, three Commonwealth agencies, nine universities and 12 consultants. Nineteen contractors were Victorian based, seven from interstate and four from overseas. The research programs covered the fields of physical oceanography, toxicants, algal nutrients, marine ecology and ecological modelling. A final report was delivered "PORT PHILLIP BAY ENVIRONMENTAL STUDY FINAL REPORT" :Harris, G., G. Batley, D. Fox, D. Hall, P. Jernakoff, R. Molloy, A. Murray, B. Newell, J. Parslow, G. Skyring and S. Walker. (1996). Port Phillip Bay Environmental Study Final Report. CSIRO, Canberra, Australia. Published on CD ROM by CSIRO Publishing, Melbourne, 1999.) 47 technical reports were also produced. In additition in April 2007 a data set collection was supplied to CMAR Data Centre by Dr John Parslow (CMAR) on CD ROM, and relates to the Port Phillip Bay Environmental Study conducted between 1992 and 1996. These datasets include: Bathymetric data, Coastline data, Data from current meters and coastal radar, Flow data for rivers, creeks and drains, Various meteorological data sets, Water salinity and temperature data, Data sets from various tide gauges and Sediment related data sets. The CD ROM also includes electronic copies of the Overview Report 39pp, Final report 248pp and the 47 Technical reports. 26, May 2015, Received Port Phillip Bay Environmental StudyData, GIS and Reports CD-ROM created by CSIRO Environmental Projects Office - robert.molloy@csiro.au (2003) from Lawrance Ferns Department of Environment, Land, Water & Planning (lawrance.ferns@delwp.vic.gov.au).
