Remotely Operated Vehicles (ROVs) and Autonomous Underwater Vehicles (AUVs) are underwater robotic vehicles used for a variety of ocean surveys and operations. Both are used for deep-sea observation, mapping of underwater environments, and surveys of biodiversity and water quality trends. While ROVs are tethered to the user by a cord called the umbilical, which provides power as well as control and video signals, AUVs are programmed for a specific course and then set loose, operating without a tether.

A new study provides strong evidence of substantial migration interference and increased mortality risk associated with the Hood Canal Bridge for aquatic animals, and may partially explain low early marine survival rates observed in Hood Canal steelhead populations.
