About the publication - 2024 Adjustment of the eastern border of the Coastal-Marine System to Blue Amazon

The publication Biomes and the Brazilian Coastal-Marine System: Adjustment of the eastern border of the Coastal-Marine system to the Blue Amazon brings the new border for the marine portion of the Coastal-Marine System, now suited to the border of the Blue Amazon. Defined by the Brazilian Navy, the Blue Amazon is the region that comprises the sea surface, waters adjoining to the seabed, as well as the marine soil and sub-soil contained in the atlantic extension projected from the shore down to the external border of the Brazilian Continental Platform.

Previously defined by the IBGE, in 2019, by the border of the Large Marine Ecosystems (LMEs), the Coastal-Marine System is now delimited in its eastern portion by the Blue Amazon, integrating the bases of the Federal Government and providing more knowledge in relation to that area of the national territory.

It should be highlighted that the border of the continental portion of this System remained unchanged, continuing with the same layout made in 2019. Like the Brazilian terrestrial biomes, which remained unchanged as well.

The product presents a Methodological Note that explains the change made, a vector base of the System and an updating of the Map of Biomes and Coastal-Marine System (2024). It can also be found in the BDiA and PGI platforms.
