You only get one chance to make a first impression. Sometimes, you get the opportunity to have an impression made on you. Seeing the E/V Nautilus for the first time, in person, can make such an impression.
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.
