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 Sustainability, Environment, Water, Population and Communities 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).

Data Lineage
Lineage statement, a general explanation
IMCRA v4.0 - meso-scale bioregions is based on IMCRA v3.3 with updates to the coastline, shelf break, a small boundary change in WA, and error corrections in NSW.
For IMCRA v3.3 two main approaches were used in integrating existing data received from State and Northern Territory marine conservation agencies: 1. Available regionalisation boundaries and descriptions were interpreted/integrated and transferred onto paper maps, and then these boundaries were digitised; and 2. Where local and sub-regional scale GIS data sets were available, these data/regions were aggregated to derive coarser meso-scale map unit boundaries using a combination of paper-based maps and GIS.
For IMCRA v4 the coastline was replaced with the national 100k coastline to provide greater consistency. Note this means that the inshore estuarine data for the NT is no longer included in IMCRA. 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. Updated boundaries for WA and NSW were incoporated based on data supplied from the relevent state agency.
