This is a subset of Minerals and Petroleum's Boreholes database - that only includes boreholes that have temperature records. The majority of the data was collected for a particular Geothermal project that concluded in late 2007. The detailed data about these observations (including correction info) are not available within the dataset itself. For further information and an excel copy of the full data, refer to VIMP report 85 - appendix 2 and an excel attachment.

This layer contains polygons defining the spatial extent, species distribution and density of seagrass meadows within Sydenham Inlet mapped from 1999 aerial photography and ground-truthing.

This layer contains polygon features which represent subtidal relief. Isobaths are linear features which are lines of equal depth that form the boundaries of the polygons.

This layer defines the approximate spatial extent, species distribution and density of seagrass and macroalgae in Western Port mapped from aerial photography in 1994 by the EPA.

This layer contains line features which represent depth contours (bathymetry) in the Gippsland Lakes.

This layer contains line features for depth contours (bathymetry) in Western Port.

Groundwater Flow Systems (GFS) have been developed in the National Land and Water Resources Audit as a framework for dryland salinity management in Australia. Originally developed in a broad national context, GFS has since been applied at the Murray Darling Basin scale and consequently CMA scale to support and underpin the development of salinity management strategies across regional jurisdictions. GFS1M joins and aggregates the mapping for the Victorian CMAs where a GFS framework exists, and presents a statewide map with a consistent attribute framework. Of the order of 100 regional GFSs is condensed into 25 statewide GFSs. GMS1M is designed for broad statewide policy use only. The GFS framework encompasses: (a) identification of generalised conceptual models of groundwater behaviour in each of the region's geological and geomorphic provinces, (b) an assessment of the physical attributes of each system, and (c) first order consideration of potential salinity management strategies applicable within each GFS. A GFS will exhibit similar physical characteristics across its extent, and generally incorporate the complete groundwater flow path from recharge to discharge. Central to the framework is the assessment of the hydrogeological responsiveness of a GFS that guides appropriate land use to assist in the management of salinity. The development GFS framework for a region is typically undertaken through intense workshopping involving local expertise, then this documented in a regional GFS map and accompanying report. The consolidation of regional GFSs into GFS1M was undertaken by PIRVic and funded through NAP.

This layer features the area cells used to record Catch and Effort data for the Port Phillip Bay commercial fisheries since April 1998. This layer is used by the Port Phillip Bay, Port Phillip Bay (Mussel Bait) and Port Phillip Bay (Purse Seine) fisheries. It is based on divisions of 5 minutes latitude by 5 minutes longitude.
