The debris discovered within the search area of the missing Titanic submersible has been assessed to be from the external body of the sub, according to a memo reviewed by CNN.
The search for the crew capsule of the Titan vessel continues, the memo says.
The debris was located on the ocean floor, roughly 500 meters (about a third of a mile) off of the bow of the Titanic, and it was found around 8:55 a.m. ET.
It was discovered by a remotely operated vehicle that was searching the seafloor, according to the US Coast Guard.
The discovery came at an urgent time for the search and rescue effort. Experts say the sub and its five passengers would be reaching the limit of the sub's roughly 96 hours of life support, having gone missing Sunday morning.
