A teenager among those believed to have died on the Titan submersible was a student at Strathclyde University in Glasgow.
Suleman Dawood, 19, was on board the vessel with his father Shahzada Dawood, 48, and three other men.
The university confirmed on Thursday that the teenager was a business school student who had just completed his first year.
In a statement addressed to the “Strathclyde community”, university principal and vice-chancellor Professor Sir Jim McDonald said: “We are deeply concerned about Suleman, his father and the others involved in this incident.
“I know you will join me in sending our thoughts and prayers to their families and loved ones.”
The submersible vessel went missing on Sunday on a voyage to visit the Titanic shipwreck.
