Bottom Topography News Today

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 theyll probably test it to see if its engine aisle from a 777, it must have a particular fingerprint. >> it definitely will. >> lets talk about the seabed, below the ocean surface where they collected that oil and talk about the seabed. its tho...

Spotted, they are taking a look to see if it could be oil coming from this airliner. that shouldnt be very hard to determine once they get some connect cal analysis. right? >> thats 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 o...

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 wo...

So that its something in the water and its something thats 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 doesnt concern us so much. if the bottom is relatively flat, the equipment is very reliable. so were more concerned, really, ...

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 doesnt concern us so much. if the bottom is relatively flat, the equipment is very reliable. so were more concerned, really, with the bottom topography than we are depth. its not uncommon to search and locate...
