  • How Many Fish Are in the Sea?

    The Atlantic - 10/05/2016

    On a clear, cold day off the coast near Woods Hole on Cape Cod, a small crane lifted the six-foot yellow torpedo-shaped machine off the boat and into the water. The researchers on the boat who were testing the robotic autonomous underwater vehicle, or AUV, sent computer signals out to the craft as it bobbed along at the surface, and received beeps in return. Once satisfied that it was ready, the researchers transmitted the command that told it to go, and the AUV disappeared under the waves. Each time they send the AUV underwater, said Hanumant Singh, an ocean engineer who splits his time between Northeastern University and Woods Hole Oceanographic Institute, “we’re holding our breath—we don’t breathe for six hours.”
