I thought one of the divers from Texas made the comment about how they found something interesting and that it dealt with containers. But that was the last I heard. This was last week.
If they're shipping containers, I guess a Texas search team might find that interesting, but seeing as this is an area where there is a lot of containerized shipping, I wouldn't read too much into that. A very large cooler, or a footlocker might be of more interest.
