It would be nice to know how the accident occurred but I think the Argentine government would prefer not to ask for help or make a big effort on the rest of this search.
My guess...gas escaping from the malfunctioning battery exploded.

Yeah, problem is, there are troughs in the Argentine Sea that are almost three miles deep. So, the sub has probably been crushed like an empty beer can.
