Valdés Peninsula
Template:Short description Template:Infobox UNESCO World Heritage Site
The Valdes Peninsula (Spanish: Península Valdés) is a peninsula into the Atlantic Ocean in the Viedma Department of northeast Chubut Province, Argentina. It is bordered by San Matías Gulf to the north. It is an important nature reserve which was listed as a World Heritage Site by UNESCO in 1999.[1]
Geography
The peninsula is about Script error: No such module "convert". in size (not taking into account the isthmus of Carlos Ameghino which connects the peninsula to the mainland). The nearest large town is Puerto Madryn. The only town on the peninsula is the small settlement of Puerto Pirámides. There are also a number of estancias, where sheep are raised.
Environment
Most of the peninsula is barren land with some salt lakes. The largest of these lakes has an elevation of about 40 m below sea level (see extremes on Earth), until recently thought to be the lowest elevation in Argentina and South America (the lowest point actually being Laguna del Carbón, Argentina, which is also the lowest point in all of South America).
Wildlife
The coastline is inhabited by marine mammals, such as sea lions, elephant seals and fur seals. The adjacent waters contain the most important breeding ground for southern right whales in the world.[1] They can be found in Golfo Nuevo and Golfo San José, protected bodies of water located between the peninsula and the Patagonian mainland. These baleen whales arrive between May and December, for mating and giving birth, because the water in the gulf is quieter and warmer than in the open sea. Orcas can also be found off the coast, in the open sea off the peninsula. They are known to beach themselves on shore to capture sea lions and elephant seals.
The inner part of the peninsula is inhabited by rheas, guanacos and maras. A diverse range of birds lives in the peninsula as well, with at least 181 species recorded, including the Cape petrel. The peninsula, along with neighbouring Punta León and Punta Loma, has been designated an Important Bird Area (IBA) by BirdLife International because it supports significant populations of Magellanic penguins (with about 150,000 breeding pairs), rock and imperial shags, kelp gulls, and South American, Cabot's and royal terns.[2]
Climate
Valdes Peninsula has a cold desert climate (BWk) bordering on a cold semi-desert climate (BSk).[3] It has a climate typical of northern Patagonia that is modified with interactions between atmospheric circulation patterns and the adjacent ocean.[4][5] The peninsula is located between the subtropical high-pressure belt (located at 30oS) and the subpolar low-pressure zone (located between 60o and 70oS), resulting in the wind being predominantly from the west.[3][5] The mean annual temperature is Script error: No such module "convert".,[3] ranging from a mean monthly temperature of Script error: No such module "convert". in winter to Script error: No such module "convert". in summer.[5] During winter, temperatures fluctuate between Script error: No such module "convert". with frosts being common, averaging 12–20 days during the season.[3] Temperatures in the summer can fluctuate between Script error: No such module "convert"..[3]
Mean annual precipitation is low, averaging Script error: No such module "convert". although this is highly variable from year to year.[3] The interior of the peninsula receives slightly lower precipitation than the coastal areas, receiving Script error: No such module "convert". per year.[4] Precipitation is fairly evenly distributed throughout the year though April–June receives the most precipitation.[5][4] The El Niño Southern Oscillation strongly influences the climate of the peninsula.[5] During an El Niño year, precipitation is higher from November to February.[5]
