Be, 38 days after the crash, would the oil have survived this far? temperatures are cold, so it depends on how warm the temperatures are and how strong the winds are for how long the oil takes to either evaporate or emulsify and sink to the bottom. >> and they'll probably test it to see if it's engine aisle from a 777, it must have a particular fingerprint. >> it definitely will. >> let's talk about the seabed, below the ocean surface where they collected that oil and talk about the seabed. it's thought to resemble rolling hills, thought to be covered with deep layers of silt. some have said t...

Spotted, they are taking a look to see if it could be oil coming from this airliner. that shouldn't be very hard to determine once they get some connect cal analysis. right? >> that's my guess. my guess is they have taken a water sample and they are going to bring it to a lab and they are going to look for the hydrocarbons in the oil, evidence of jet fuel. obviously the chemical composition of jet fuel, the hydrocarbons are going to be different than boat fuel. they are looking for the signature of jet fuel in that water sample. >> so bottom line right now, ellen, give me your analysis of wher...

Possibility of the pinger being located, then what they would normally do is basically try to develop from the surface ships, a 3-d map of the topography to get a real good understanding of what the terrain is. after that, they would be able to put down the underwater vehicles and be able to create missions based on whatever the underlying bottom topography would be in the area. >> anish patel and fred hegg, you added value. thank you so much. my next guest says despite headlines around the world, you are the safest you have ever been. i got this. [thinking] is it that time? the son picks up...

So that it's something in the water and it's something that's pinging, or giving us a repetitive signal. it just may be that due to the different temperatures, it may be at a different rate. >> understood. mike, this is nearly three miles underwater. how reliable are these pings and how different are they to track back to their source at that depth? >> well, the depth really doesn't concern us so much. if the bottom is relatively flat, the equipment is very reliable. so we're more concerned, really, with the bottom topography than we are depth. it's not uncommon to search and locate objects at...
