Patagonian Shelf Patagonian Shelf The Patagonian or Argentine Shelf is part of the South American continental shelf belonging to the Argentine Sea on the Atlantic seaboard, south of about 35°S. It adjoins the coasts of Uruguay, Argentina and the Falkland Islands. Various authorities quote different dimensions of the shelf, depending on how they define its limits. Quoted statistics cites its area as being from 1.2 to 2.7 million square kilometres and its maximum width as being between 760 and 850 kilometres. The shelf itself can be divided into a 100 km band where the seabed slopes at about then a wide plain
Patagonian Welsh now bilingual in Welsh and Spanish. The Welsh people first arrived in Patagonia in 1865. They had migrated to protect their native Welsh culture and language, which they considered to be threatened in their native Wales. Over the years the use of the language started to decrease and there was relatively little contact between Wales and the Chubut Valley. The situation began to change when many Welsh people visited the region in 1965 to celebrate the colony's centenary; since then the number of Welsh visitors increased. In 1945 and 1946 the BBC World Service broadcast radio shows in Patagonian Welsh.
