Triton does have an office in Brazil, but had not been able to get permission for a study as far as I know.

Triton’s South American headquarters is located in Rio de Janeiro, Brazil and is responsible for project development, licence acquisition and industrial services in the region. Triton Logging Brasil Ltda. is working with public and private reservoir managers and the government of Brazil to create sustainable economic, social and environmental value from the region’s immense volumes of submerged tropical timber.
