Hydrosphere Technology by Alex Scott. The evolution of the submarine gave people the power to use new technoligies to explore the ocean. Submarines have been around for hundreds of years but in 1954 Nautilus was released as the first nuclear powered submarine. In 1959 Skipjack was the first high speed nuclear powered submarine. 1960 was when Triton was unleashed it was the first submarine to travel around the entire world. Triton went 36,014 miles in 84 days. In 1968 the Los Angeles submarine class was the new fastest submarine in the world going 30-33 Knots. The Akula class submarine passed it up at recorded speeds of 35 Knots. multiple research vessels have made contributions to researching the oceans also. In 1872 the HMS Challenger Expidition was the first expidition devoted to researching the ocean. In 1893 the Fram discovered their was no continent in the Arctic. 1925 was when the Meteor became the first Vessel to extensivley use echo sounder technology. In 1968 the Glomar Challenger was the deep sea research and drilling vessel that confirmed seafloor spreading. In 1978 Seasat-A became the first satelite to study the ocean. Over time the study of the Hydrosphere has changed so much.
