It encompasses a marine strip that stretches between 20 and 40 nautical miles following the shoreline of Argentina, from the Province of Chubut up to the Rio de la Plata. The area is part of the Magellanic penguin's migratory path. The corridor has been proposed to minimize potential interaction by the overlapping of the species migratory population with hydrocarbon and commercial navigation transport.

Conservation Status



Argentine – Uruguayan common fishing area and Argentine Exclusive Economic Zone.

Biogeographical Region

Temperate seas of South America.  Magellanic Province. Ecoregion: North Patagonian Gulfs and the Uruguayan - Buenos Aires shelf.


112.500 km2

Types of Habitats

Pelagic and benthic shelf environments.

Species Richness

There are no specific biodiversity studies for this area.  Satellite monitoring surveys indicate that many seabirds and marine mammals use this area as a foraging ground.

Main Uses

Fisheries. Maritime transport, a proportion of which is associated with the oil and gas industry.


Acute contamination (oil spill accidents) and chronic (regular discharge) related to oil transport.  Overfishing and discards of by-catch.  By-catch and incidental mortality of seabirds and marine mammals.

Management - Main Government Bodies

Binational Argentine-Uruguayan bodies: Comisión Técnica Mixta del Frente Marítimo (CTMFM). National Bodies: Prefectura Naval Argentina, Consejo Federal Pesquero, Subsecretaría de Pesca y Acuicultura, Secretaría de Ambiente y Desarrollo Sustentable (SAyDS)

Level of Protection

There are no marine protected areas in this sector.  The proposed corridor crosses different fishing resource management areas.
