Seafloor mapping is a critical tool for understanding ocean habitats. As you can imagine, the seafloor is really hard for most people to see without mapping tools.

Dr. Greene and his Canadian collaborator Dr. Vaughn Barry recently revealed, in detail, a 125km-long series of faults that run from Washington to Victoria associated with the Devil’s Mountain Fault Zone.
