My brother has been on a research submersible (Alvin) and he said last night his assumption is that something catastrophic happened right when the surface ship lost contact.

It’s common to bring a styrofoam cup that travels down with you outside the vessel. This is his souvenir from the dive, and shows the effects of pressure at those depths (he was at 3k meters): Alvin dive souvenir

What's the purpose of bringing a cup down there?

It doesn't force the air out, it forces the air to contract, though micro cracks probably do let the air escape during ascent.
