IMCRA MESOSCALE V4

Brief description

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/
