VIDEO: Mesobot dives into the Twilight Zone

Mesobot is a brand new underwater vehicle designed to reveal what lives in the ocean’s twilight zone.

Mesobot can follow animals as they move through the darkness and as they migrate from the depths to the surface and back. The twilight zone is vast and remote, but is threatened by unregulated fishing and climate change.

The development of Mesobot is a collaboration between Woods Hole Oceanographic Institution (WHOI), Monterey Bay Aquarium Research Institute (MBARI), Stanford University, and the University of Texas Rio Grande Valley. The robot is designed to let scientists observe the twilight zone by autonomously tracking individual animals for hours, or even days, without disturbing the environment or disrupting their behavior.
