OCEAN SCIENCE!

Dive into the fascinating history of ocean science, beginning with Sieur Freminet's invention of the first rebreathing device in 1772—a self-contained air apparatus that tragically led to his death due to oxygen deprivation. Explore the impact of chemical dumping that persisted until 1972, when the U.S. banned the disposal of toxic agents in the ocean. Discover free diving's ancient roots and significant milestones, including the first documented underwater pictures in 1946. Despite the demand for oceanic exploration, 90% of the ocean remains uncharted, highlighting the mysteries yet to be uncovered.

  1. History of OCEAN SCIENCE! By Anne Gillis

  2. The First Scuba Device • In 1772, Frenchmen, SieurFreminet invented The Rebreathing Device that recycled the exhaled air from inside a metal barrel. • This was the first self-contained air device. • Freminet died from lack of oxygen after being in his own device for twenty minutes.

  3. Chemical Dumping • It wasn’t until 1972 that the U.S banned dumping chemical weapons into the ocean. • 32,000 tons of nerve and mustard agents had already been dumped into the ocean waters off the United States. • 26 chemical weapon dump sites in the ocean • The effects on the ocean are unknown but if it leeks it will last up to 6 weeks before being broken down into something nonlethal

  4. Free Diving • Free diving has been around as far back as 4500 b.c. when people had to dive to find food and seashells or whatever they needed for survival. • Korean woman used to dive to the sea floor to collect pearls and sponges. • In 1911 in the Aegean sea, an Italian flag ship dropped anchor. • Anchor snapped and was lost under 77 meters of ocean. • Several days of unsuccessful attempts lead to the captain searching for someone who could • YorgosHaggiStatti clamed he could do it. • In exchange for five Pounds Sterling and permission to fish with dynamite. • Yorgos locate the anchor and passed a rope through it so that the crew could retrieve it. • Thus becoming the first deep diver in history.

  5. The first Underwater Pictures • The first photos taken of the sea was of the ocean floor by Kenneth L. Hunkins, Bruce C. Heexen,andRobert J. Menxies in 1946 • They took pictures of the Arctic Ocean floor • They noted that their was a lack of life in every aspect.

  6. What's making History Today in the Ocean! • Today because of popular demand for an ocean view and your own privet getaway people have started to create their own land. • Using sand from the ocean floor as the base as well as rock. You could have a house here for a small price of 25 to 45 million dollars. Off the shore of Dubai

  7. Did you know…. • We actually don't know much about oceans. 99% of all living space on Earth live in the ocean and less than 10% of that has been explored. • The ARCTIC Ocean is the smallest, shallowest and coldest.
