An inshore regionalisation of Australian waters derived from biological and physical data, including the distribution of demersal fishes, marine plants and invertebrates, sea floor geomorphology and sediments, and oceanographic data.The meso-scale regionalisation was compiled from information supplied to the Australian Government Department of Climate Change, Energy, the Environment and Water by the relevant State, Northern Territory and Commonwealth marine research and management agencies.The seaward extent for the meso-scale IMCRA coverage is defined by the 200m isobath except where this boundary extends beyond the Australian Exclusive Economic Zone (AEEZ).

A regionalisation of Australian waters (excluding waters adjacent to the Territory of Heard Island and McDonald Islands, and waters adjacent to the Australian Antarctic Territory) derived from deep-water demersal fish assemblages. A total of 41 onshelf and offshelf provincial bioregions were identified for IMCRA v4.0.Onshelf provincial bioregions are based on the 17 IMCRA v3.3 demersal provinces and biotones identified in 1997.Offshelf provincial bioregions were defined in 2004 as part of a program run by Geoscience Australia, CSIRO Marine Research and the National Oceans Office. They represent units that contain broad patterns in biodiversity, as represented by deep-water demersal fish assemblages, based on the assumption that the demersal fish distributions are a surrogate of marine faunal distributions. Below 2,000 m water depth, the boundaries of the benthic provincial bioregions are defined solely by the NMB (National Marine Bioregionalisation) geomorphic features data set. A total of 24 offshelf benthic provincial bioregions were defined on this basis, including 15 core bioregions representing areas of endemism, and 9 transition zones representing areas of faunal mixing.For IMCRA v4.0 the coastline was replaced with the national 100k coastline to provide greater consistency. The Australian EEZ limit was sourced from AMB v2. Based on a decision by the Bioregionalisation Working Group, the shelf break from IMCRA v3.3 was largely retained, although in some instances the shelf break from the NMB (National Marine Bioregionalisation) provincial bioregions was used.

A Regionalisation of the Australian coastal waters to the Australian 200 meter isobath derived from biological and physical data, (eg. coastal geomorphology, tidal attributes, oceanography, bathymetry, intertidal invertebrates). Attributes include: named regions and their location(s) within provinces. Data were compiled for Version 3.1 from the most up-to-date data available as of 7 March 1997. The meso-scale regionalisation was compiled from information supplied to Environment Australia by the relevant State, Northen Territory and Commonwealth marine research and management agencies. The outer seaward extent for the meso-scale IMCRA coverage is defined by the 200m isobath except where this boundary extends beyond the Australian Exclusive Economic Zone (AEEZ). Please note this dataset as well as the current preferred dataset of Victorian Biounits are available under ‘Marine Biogeographical Regions’ on CoastKit, Victoria’s online data repository of marine and coastal information: https://mapshare.vic.gov.au/coastkit/

Bathomes within Australian waters is a depth-related biomic regionalisation of Australian waters derived primarily from the distribution of demersal fishes and bathymetric data. The data incorporates the analyses of Last et. al. (2005), Vince et. al. (2009), and advice from the CERF Marine Biodiversity Hub, to give a complete depth by bioregion coverage for Australian waters. The data was generated as part of the marine bioregional planning process to assist with decision making in relation to meeting Goal 2 of the NRSMPA Goals and Principles.NOTE: This item refers to a dataset available under a Departmental Deed. The related metadata is available for download as a Word document as necessary.

This dataset presents an oceanographic regionalisation for the Australian region using a multivariate pattern classification system, constructed as part of the CSIRO Bioregionalisation Project. The oceanographic regionalisation comprises an analysis of temperature, dissolved oxygen, salinity, nitrate, phosphate and silicate variability with season and depth. Data sources include research vessels, satellites, and surface drifters, and in particular the archive of vertical profiles of temperature, salinity, oxygen and nutrients comprising over 130,000 stations in the seas adjacent to Australia collected as part of the Division of Oceanography's Oceans-EEZ Analysis System.
