It s incredibly 01:37.964 --> 01:41.868 align:left position:85% line:83% size:5% well supported by the community of researchers that use the vehicle 01:41.868 --> 01:47.006 align:left position:85% line:83% size:5% and the National Science Foundation and the Office of Naval Research. 01:47.006 --> 01:55.815 align:left position:65% line:83% size:25% Of its thousands of dives since 1964, there is one often held as the most significant the discovery 01:55.815 --> 02:03.089 align:left position:67.5% line:83% size:22.5% of hydrothermal vents near the Galapagos Islands. These alien-like deep-sea communities where 02:03.089 --> 02:12.031 align:left position:70% line:83% size:20% life thrives without the light of the sun were unknown to humankind before Alvin visited them. 02:12.031 --> 02:17.070 align:left position:80% line:83% size:10% The discovery of vents changed the way we think about life. And Alvin was really 02:17.070 --> 02:20.773 align:left position:72.5% line:89% size:17.5% the workhorse that did all that work in 1977. 02:20.773 --> 02:23.877 align:left position:15% line:83% size:75% If you look at it on a map it looks like a blue expanse, 02:23.877 --> 02:28.848 align:left position:70% line:89% size:20% but down on the bottom it s a different planet. 02:28.848 --> 02:34.521 align:left position:87.5% line:83% size:2.5% Now, Alvin is poised to continue its revolutionary scientific work. 02:34.521 --> 02:42.529 align:left position:75% line:83% size:15% With a new set of upgrades and deeper depth rating, the possibilities are endless. 02:42.529 --> 02:45.899 align:left position:87.5% line:83% size:2.5% Alvin will be able to map things that we ve never seen before 02:45.899 --> 02:51.571 align:left position:12.5% line:83% size:77.5% that otherwise have not been accessible to human discovery. 02:51.571 --> 02:55.308 align:left position:10% line:83% size:80% How has the research conducted with the Alvin submersible 02:55.308 --> 03:02.849 align:left position:72.5% line:83% size:17.5% impacted our understanding of the oceans? And what can Alvin s incredible history of discovery, 03:02.849 --> 03:06.849 align:left position:10% line:83% size:80% inspiration, and daring tell us about life on Earth and beyond?
