Wreckage will stand out when they run side scan sonar. >> they haven't done topography mapping so it's like you're starting from scratch. >> a little bit, wolf. you heard the previous commentator talking about what we know about the bottom there. the good news is hms echo is nearby, fitted with the right type of gear to gi a very sort of quick ocean bottom map expedition that could be the information that would help move this faster. >> how deep can navy divers go? >> navy divers generally about 1,000 feet for man diving. >> so there's no way there's going to be anybody down -- you have to sen...

But since the chinese issued those photographs and announced they found those white objects or spotted them from one of their aircraft, nothing else has been heard. we've seen a lot of debris that's been spotted and ruled out. we saw ocean tankers, and things that end up in the indian ocean because of the currents. this may fall into that category. certainly they don't seem to be a focus of the search at this point. >> matthew, thanks very much. the process now centers on listening for trying to reacquire the source of those two hours and 13 minutes of pinging noises. doing that before launchi...

Listening for trying to reacquire the source of those two hours and 13 minutes of pinging noises. doing that before launching a much longer effort of taking sonar pictures mile by mile of the ocean bottom. we want to give you and explanation of what's going on. we go commander william marks. commander correct me if i'm wrong it's my understanding on sunday over the course of the two hours, the pings got stronger then weaker. did that mean the ship was closer and then farther away. >> at that point those were very encouraging signs and now we're being more optimistic. then a couple of pings gav...
