A debris field has been discovered during a search for a missing submersible that was carrying five people near the Titanic wreckage, the U.S. Coast Guard said Thursday.

The discovery was made by a remotely operated vehicle searching the area, which is being evaluated by experts within the unified command. That group reportedly consists of the U.S. Coast Guard, U.S. Navy, Canadian Coast Guard and OceanGate Expeditions.

A press briefing will be held at 3 p.m. EST to discuss the findings from the Horizon Arctics remotely operated vehicle or ROV, the Coast Guard said.
