down here and in complete blackness. one advantage, quite calm at this level, very few currents or anything to affect anything down here, but controlling something down here from way up here, getting it back and forth, this is more experimental than the way we have been talking about we talk about like it's a simple thing to do. it's not simple at all. even though they have done it before, hasn't been done so many times this this is routine, michaela. >> i imagine though, like anything, when you go in to learn one thing, end up learning all sorts of other things, that this is unchartered area we have been talking about before. they probably are getting some data and research that they can use for other things. >> yeah, once they finish this mapping of the ocean floor out there, by the time they have been able to go with ships like the "hms echo" and side-scan sonar and pictures of the ocean floor here, yes, we will have a body of knowledge that we absolutely do not have right now about that portion of the ocean floor.
