A team of archaeologists with the Black Sea Project lowers a remotely operated submersible named Little Hercules from a research vessel. In 2000, when this photo was taken, the project discovered several impeccably preserved ancient shipwrecks in the depths of the Black Sea off the coast of Turkey.
