&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.
