The North Patagonian Gulfs marine ecoregion covers the bays and offshore shelf of a portion of the southern coast of Argentina. The entire ecoregion is on the Patagonian Shelf, The ecoregion is part of the Magellanic marine province. It is thus part of the Temperate South America realm. .

Physical setting

The northern border of the ecoregion, at 41°S, reaches out for 260 miles into the Atlantic Ocean from the mouth of Río Negro (Argentina). The ecoregion is bounded on the south at 47°S at the southern point of San Jorge Gulf. In between are 1,890 coastal miles. The bordering coast is generally low, dry scrub and grassland, characterized by the Argentine Monte ecoregion along the northern coast and Patagonian Desert along the southern.. Few rivers feed the ecoregion; exceptions are the Rio Negro in the north and Chubut River in the south.

Currents and climate

The Atlantic South Equatorial Current (SEC) flows directly into the ecoregion from the East, bringing warm water from the South Atlantic Ocean. As the SEC approaches the eastern point of Brazil at Cape São Roque, it splits, with the North Brazil Current (NBC) flowing along the coast to the north and west, and the Brazil Current flowing south along the eastern coast. The Brazil Current is a western boundary current, flowing at a rate averaging 4 Sverdrups (Sv), at a mean speed of 60–100 centimetres per second (1.3–2.2 mph). Surface temperatures range from 22–28.5 °C (71.6–83.3 °F).
