Exploration Vessel (E/V) Nautilus is a 64-metre research vessel operated by
the Ocean Exploration Trust under the direction of Dr. Robert Ballard, the
man who is best-known for finding the wreck of the Titanic and the German
military ship Bismarck.

This year is Nautilus's most ambitious expedition season yet, exploring
sites ranging from the Gulf of Mexico to British Columbia in late
September.

It will explore and map the Galapagos Rift and the site of the first
hydrothermal vent discovery in 1977. You can catch up on progress here.

Eugenie Clark, a marine biologist and ichthyologist, who died on Wednesday, helped the public understand and appreciate the much maligned shark.

Temple University researchers have assembled the largest and most accurate tree of life calibrated to time, and surprisingly, it reveals that life has been expanding at a constant rate.

"While I was perfectly aware of the danger, it was hard not to be mesmerized by the rare chance to experience the incredible energy of the Earth’s underlying forces," says Sam Cossman, who one mont...
