We began diving on the Eratosthenes Seamount at around 3 am on August 15th and dove for nearly 24 hours. We were searching for any active seep sites and methane discoloration of the sediment. We found numerous sink holes, animals, and finally active seep sites and tube worm communities.
Nautilus was diving at the Eratosthenes Seamount in search of signs indicating active hydrothermal vents, where warm chemical-rich water is seeping out of the seafloor, and the exotic animals that live on them. While searching for evidence of geological and biological activity, we came across both modern and ancient garbage.
