The OCEARCH was docked Friday along the Northbank Riverwalk near the Hyatt Downtown. The 126-foot seagoing research laboratory was toured by Mayor Alvin Brown and about 200 people, including a group of students from the University of North Florida. The scientists and crew departed for the Atlantic Ocean off North Florida where they intend to capture great white sharks, collect tissue samples, tag them with radio transponders and release them.
