摘要：

Application of sidescan sonar at the regional scale of the Abrolhos Bank, with ground-truthing by remotely operated vehicles and mixed-gas diving operations, revealed a much more complex habitat mosaic than previously recognized. The regional benthic habitat map indicates 8844 km(2) of reefs (earlier estimates from remote sensing were around 500 km(2)) and 20,904 km(2) of rhodolith habitat-the world's largest continuous bed. Integration of the regional megahabitat map with spatially explicit data on the distribution of marine protected areas (< 0.2% of each benthic megahabitat area) and economic activities with the highest potential of environmental impact (fishing, mining, oil and gas exploitation and dredging) reveals the need of a regional scale spatial planning process engaging conflicting sectors.
