In the early 1800's, James Weddell Scottish took 3 voyages to the southern ocean while being no only interested in profit, but interested in exploration. During his voyages, he discovered the Weddell seal, reached the farthest point south, and wrote the book, 'A Voyage Towards the South Pole'. Later in the 1800's, another person made the discover for not only Antarctica, but also the North Pole. James Clark Ross made 2 explorations in his life, 1 in search for the North Pole, and 1 for exploring the Antarctic peninsula. During his second voyage, he discovered the Ross Ice Shelf, the Ross Sea, and named a volcano Erebus after 1 of his 2 ships.
In the late 1800's, Adrien de Gerlache de Gomery was the first one to lead an exploration in the 'Heroic age of Antarctic Exploration'. During this exploration, he discovered a strait between Antarctica and the Islands of Palmer Archipelago. He also discovered the Belgica Antarctica, which is a flightless midge only 2-6mm in length. In the early 1900's, José María Sobral was the first Argentines to go and explore Antarctica that was led by Otto Nordenskjöld. His first time to Antarctica was a tragic one, because the ship he was on sank, forcing him, his crewmates, and his captain stranded on Antarctica. After him, many other voyagers took the trip to explore Antarctic Peninsula.
