A research professor from UNC Wilmington is part of the team that launched the sub.
Dr. Steve Ross is renowned for his marine research. He is serving as the chief scientist for OceanGate, the foundation that created the Titan submersible.
Officials at UNCW said Ross is safe, but the search continues for the five people lost underwater - their oxygen supply running low.
The Coast Guard said Wednesday it is bringing in more ships and underwater vessels to search for a submersible missing in the North Atlantic after detecting underwater sounds, including banging noises, that provided a glimmer of hope three days after the Titan disappeared while bringing five people down to the wreck of the Titanic.
