Editor-in-chief · Marco Três
Annie Grellmann is a journalist and the editor responsible for Marco Três, the live guide to the Triple Frontier (Foz do Iguaçu, Puerto Iguazú and Ciudad del Este).
The newsroom publishes with automated curation and human editorial supervision: reporting always starts from a cited primary source, a figure only runs with a source, and a factual correction is made in the published text, with the date of the revision.
Every story says where the data came from and links the source. Our own measurements (river flow, bridge queue, exchange rates) are identified as house measurements, with the yardstick named. The method, corrections policy and funding are on the transparency page.
