    I’ve read a probable scenario about accidents with small DSVs in the book Below(Edit) the Edge of Darkness (about marine biology of bioluminescence and the tech developed by the author to film/record it):

    There was a small leak in a valve, used for emergency operation IIRC and the author noticed that going down - she was still light enough to ascend but she said had she been a few hundred meters deeper, she never would have made it back up due to the extra weight.

      What you’re describing is similar to the leading theory for what happened to the USS Thresher. Flooding occurred and then when the sub went to emergency blow its ballast to surface, ice formed in the piping blocking the pressurized release of ballast water, causing the sub to sink uncontrollably. There’s a good gif doing a better job explaining it on the wiki. Interestingly, the evidence used to determine this theory was gathered by Robert Ballard the famous oceanographer who then went on to be the first to find the remains of the Titanic. It all come full circle!
