A close encounter with a sperm whale 600 metres beneath the Gulf of Mexico
The Nautilus expedition has recorded a rare encounter with a sperm whale at 598 metres below the Gulf of Mexico off the coast of Louisiana.
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.
