Amusing Monday: Celebrating Alvin’s animals

This year is the 50th anniversary of Alvin, a deep-sea vehicle that has made some incredible scientific discoveries over the past half-century.

The latest issue of Oceanus magazine is a special edition that takes us through the history of Alvin, including its part in locating a lost hydrogen bomb, investigating the Deepwater Horizon oil spill and documenting the remains of the Titanic.

Read “The Once & Future Alvin,” Oceanus Summer 2014.

What really drew my attention to this issue is a photo feature called “Alvin’s Animals.” It was posted as a slide show in the online version of Oceanus. It registered high on my amusing meter, and I encourage you to click through the buttons that take you from one odd-looking creature to the next.

One of Alvin’s most significant discoveries came in 1977, when the submersible traveled to the Galapagos Rift, a deep-water area where volcanic activity had been detected. Scientists had speculated that steaming underwater vents were releasing chemicals into the ocean water. They got to see that, but what they discovered was much more: a collection of unique clams, worms and mussels thriving without sunlight.

These were lifeforms in which bacteria played a central role at the base of a food web that derives its energy from chemicals and not photosynthesis.

Since then, other deep-sea communities have been discovered and documented throughout the world, with hundreds of new species examined and named.

The Oceanus article also describes in some detail the just-completed renovation that has given Alvin new capabilities. The people responsible for various aspects of the make-over are interviewed in this special edition.

The first video on this page is by Woods Hole Oceanographic Institution celebrating Alvin’s 50th birthday. The second is a walk-around the newly renovated craft by Jim Motavalli, who usually writes about ecologically friendly automobiles.
