Integrated Marine and Coastal Regionalisation of Australia (IMCRA) v4.0 - Meso-scale Bioregions

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.\\n\\nThe meso-scale regionalisation was compiled from information supplied to the Australian Government Department of the Environment and Heritage by the relevant State, Northern Territory and Commonwealth marine research and management agencies.\\n\\nThe 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).

Explanation

The data was compiled at scales varying between 1:100,000 and 1:2,500,000, giving a locational accuracy varying between 100-2,500 metres.

Explanation

The original IMCRA v3.3 attributes were assumed to be correct as received from State and Northern Territory contributors.\\nAttributes were simplified for v4.0 and include:\\nMESO_NAME = meso-scale bioregion name\\nMESO_NUM = meso-scale bioregion number\\nMESO_ABBR = meso-scale bioregion name abbreviation\\nWATER_TYPE = water type from NMB provincial bioregions\\nAREA_KM2 = area in square kilometres

Statement

&quoteIMCRA v4.0 - meso-scale bioregions&quote is based on IMCRA v3.3 with updates to the coastline, shelf break, a small boundary change in WA, and error corrections in NSW.\\n\\nFor IMCRA v3.3 two main approaches were used in integrating existing data received from State and Northern Territory marine conservation agencies:\\n1. Available regionalisation boundaries and descriptions were interpreted/integrated and transferred onto paper maps, and then these boundaries were digitised; and\\n2. 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.\\n\\nFor 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.\\nUpdated boundaries for WA and NSW were incoporated based on data supllied from the relevent state agency.
