2.03 Marine Science Honors: 1872-2013 Timeline
HMS Challenger: 1872
During this time, scientists investigated the great big, deep sea. They discovered 4,000 new marines species, they studied the currents, temperatures, and water salinity. The scientists used a bathysphere to drive down a mile in order to study deep sea fish and their habitats.
Marine Survey of the Pacific: 1899
Alexander Agassiz, zoologist, made several expeditions on Albatross to study the coral reefs throughout the Pacific Ocean. This ship's crew members worked on soundings and they collected specimens.
The Titanic Sinks: 1912
This devastating accident lead to a concerned effort to construct an acoustic means of discovering different objects in the water. The White Star Liner Titanic sinks right after striking an iceberg in the North Atlantic Ocean.
First Acoustic Exploration of the Sea Floor: 1914
A Canadian inventor uses what is known as an oscillator to bounce sound waves between an iceberg and the sea floor. This great technology eventually lead to the development of sonar, which allows submarines to signal one another. It also allows them to detect icebergs.
First Deep Ocean Dive: 1934
A deep sea expedition occured in a tethered sphere known as a bathysphere. This sphere went a depth of 3,000 feet off of the coast of Bermuda. They used this to discover a bizarre creature that had never been seen nor heard of before.
Deep Sea Submersible Alvin: 1964
This was the first U.S. deep diving submersible and the first deep sea submersible that was capable of carrying passengers. Alvin became one of the most famous deep sea vehicles. It made over 4,000 dives during its lifetime!!
Development of Portable Underwater Habitat: 2012
Michael Lombardi, National Geographic, developed a portable, underwater habitat that could assist divers with decompression. This new form of habitat enabled extended dives on the deep coral reefs with a minimal cost and infrastructure.
