Because light gets absorbed quickly by water, it is difficult to see large areas of the seafloor. On interesting sites, we therefore collect hundreds of still images and stitch them together to create photomosaics so that we can get a better picture of them. This album includes photomosaics of shipwrecks, seafloor gouges, and hydrothermal vent sites found on Eratosthenes Seamount in the eastern Mediterranean Sea.
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.
