一、巴塔哥尼亚海域的地理环境在南美洲的最早期的简略地图上从一开始就把其最南端的部分称为巴塔哥尼亚。由于这一地区幅员广阔,属性迥异,因而此名便一直沿用至今。如今所称的巴塔哥尼亚海域,包括火地岛区及附属岛屿等。巴塔哥尼亚陆架是世界少有的,其延伸范围一直超过200海里专属经济区,是南半球最大陆架之一。陆架(0～200米)总面积300,300平方海里,斜坡面积(200～1,000米)为58,310平方海里。架上深度小于100米占多数。斜坡在巴塔哥尼亚北部很陡峭,而南部较平缓。在42°S以南的底质粗糙但仍可拖网,在勃特伍特堆的周围还是很好的拖网
I. The Patagonian Geography The southernmost part of South America, from the very beginning, referred to the southernmost part of it as Patagonia. Due to its vast territory and varied properties, this name has been in use ever since. The so-called Patagonian waters, including Tierra del Fuego and its associated islands. The Patagonia shelf is a rare in the world extending over 200 nautical miles exclusive economic zone and one of the largest shelves in the southern hemisphere. The total area of 300,300 square nautical miles of the shelf (0-200 meters) and 58,310 square nautical miles of slopes (200-1,000 meters). Rack depth less than 100 meters accounted for the majority. The slopes are steep in northern Patagonia and the south is relatively flat. Sediment rough but still trawlable to the south of 42 ° S and still well trawled around the Pilewood Heap
