Friday, September 19 Did You Know? The largest octopus weighs about 15 kg (Octopus dofleini). An Octopus has three hearts and it can squeeze through a hole the size of a 10 -cent coin. Hapalochlaena species can inject enough venom in one bite to kill several adult humans. They can adopt a two-tentacles "walk" that frees up their six remaining limbs and makes them look like an armed vehicle. http: //www. youtube. com/watch? v=BULXKr z.

Diving Vessels Also called submersibles ROVs= Remotely Operated Vehicles (tethered) AUVs= Autonomous Underwater Vehicles (untethered) Bathysphere, allowed aquanauts to go to deeper Bathysphere depths Bathyscaphe is a steel un-tethered submersible that could be controlled. Deepest dive in history (1960). Alvin is a self-propelled machine with mechanical arms that can pick up specimens and can carry three humans
The Bathysphere
1880 to 1950 V. Walfrid Ekman – Figured out the Ekman Spirals and Ekman Layer Fridtjof Nansen – Made the Nansen Bottle. Now people could take samples of water from different depths of water. Beebe and Barton – First bathysphere to 4, 000 feet Steel sphere at the end of a long cable (tethered)
Marie Thorp and Bruce Heezen – made the first map of the ocean bottom and provided evidence for theory of Continental Drift. Auguste Piccard – First bathyscaphe to reach the bottom of the Mariana's Trench at 35, 800 feet.
