A GLASGOW student is on board the missing the Titanic submersible.

Suleman Dawood, 19, is a student at the University of Strathclyde.

He is one of the five people trapped on board the submarine, along with his father Shahzada, 48.

The principal and vice-chancellor of Strathclyde University shared a message with students following the news. 

In an email, Professor Jim McDonald wrote: “I write to you with a heavy heart to share the news that one of our students, Suleman Dawood, is a passenger on board the submersible that is missing in the North Atlantic.

“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.

“Suleman is a Strathclyde Business School student and has just completed his first year with us.”

Labour MSP Pam Duncan-Glancy said her thoughts were with the teenager and his family while speaking at First Minister’s Questions in Holyrood.

She said: “The young man on the Titan submersible is a student in Glasgow.

“I’m sure that everyone here will join me in sharing their thoughts with him and his family at this unprecedented and difficult time.”

The submersible went missing on Sunday with five people onboard.

The vessel lost communication with tour operators while about 435 miles south of St John’s, Newfoundland, during a voyage to the Titanic shipwreck off the coast of Canada.

The US Coast Guard is still treating the hunt for the missing submersible as an active search and rescue.

Rear Admiral John Mauger confirmed the main focus of the US Coast Guard and the unified command in charge of the operation was to retrieve the vessel in what is still being seen as an active search and rescue.

He told Sky News: “We continue to keep the crew members and the families in our thoughts as we proceed with this search and rescue while we’re cognisant of the time and we’ve factored in a lot of data and information into the search.

“This is still an active search and rescue at this point and we’re using the equipment that we have on the bottom right now, the remote operated vehicles to expand our search capability, and then also to provide rescue capability as well.”

When questioned about the noises detected by the sonar buoys dropped into the ocean, he revealed initial reports found that it was “ocean background noise”.

He said: “We’ve taken that information and shared it with top leading experts from the US Navy and the Canadian Navy, and they’re working on the analysis of that information, they’re continuing to work on the analysis of that information.

“The initial reports is that there’s a lot of the sounds that were generated were from background ocean noise, but they continue to … look for all available information there.

“What’s important to me, and what’s important as the unified command, is that we’ve continued search in the areas where noise was detected with the ROVs that we have from the time of that detection, so we’re not waiting for this analysis to take action.

“The analysis is really helpful to our overall search-and-rescue efforts, but we’re not waiting on it, we’ve moved the remote operated vehicles that we’ve had on site to those areas where noise was detected.”

In a statement published online Guillermo Sohnlein, co-founder of OceanGate, said he believed the time window available "is longer than what most people think". 

It was thought that oxygen would run out around midday on Thursday.
