Authorities here in australia. they have been refining the search field for debris based on the calculations of oceanic drift and important to point out theres two searches going on here. theres the search for the underwater pings and then the search for debris and its a debris search field expanded by some 6,000 square miles which isnt all that much when you consider that the current size of the debris field is a quarter of what it was ten days ago and theyre narrowing down that search field. l...

Making that assumption. >> i wanted to ask you, erin, do you know why they expanded the search area after they had narrowed it yesterday? >> well, they didnt give us a specific reason. every day theyve been refining this search area based on their analysis of the oceanic. this is the search area for the debris, keep in mind, and today they expanded it by some 6,000 square miles which may sound like a lot but considering the current search area is about a quarter of what it was some ten days ago,...

An operational life of 30. the question becomes when are they going to feel comfortable to make that assumption? no timetable from the australians so far. also according to the press statement from the joint agency coordination center this morning, search field for the debris, two searches going on here, underwater search for pings and search for debris. the debris search field narrowing today by 3,000, 3,800 square miles, yesterday increased by 6,000 squares mile. a moving search field. its bas...

Where we find cnns aaron mclaughlin. lets start with the search zone. after shrinking all this past week why was the area suddenly expanded tooed? >> reporter: officials today didnt say specifically. but they have been steadily refining the debris search zone. they really only expanded around 6,000 square miles today which isnt all that much when you consider that the current debris field is about a quarter of what it was some ten days ago. while theyve been really successful at refining this se...

Do not worry about the other search areas because the aircraft had been looking for wreckage on the surface and had been taking a count of 30 days of oceanic drift. but the satellite has essentially given us this area here as the most likely place where mh 370 entered the water. now, what is significant about this is that yesterday or a couple of days ago, haixun 01 had its encounter with the electronic pulse in this location here. ocean shield is currently working up in this location there. so ...

Underwater search area which is reflected here. its the area where the aircraft might have entered the water is reflected by these boxes here. dont worry about the other areas because the aircraft have been looking at footage on the surface and been taking account of 30 days of oceanic drift. but the satellite has essentially given us this area here as the most likely place where mh-370 entered the water. now, whats significant about this is that yesterday, or couple days ago, haixun 01 had its ...

The area where the aircraft might have entered the water is reflected by boxes here. do not worry about the other search areas because the aircraft have been looking for reccage on the surface and have been taking account of 30 days of oceanic drift. but, the satellite has given us this area here as the most-likely place where mh 370 entered water. now what is significant about this is that yesterday, or couple days ago, hisuin 01 had its encounter with the electronic pulse in this location here...

Find any sign of that debris. again, it gets under way right away. >> all right. nbcs sara james. great information. thank you. the object spotted a few days ago could have drifted hundreds of miles. and the search area is over a massive stretch of ocean. kathleen doh a,n is a research scientist whose specialty includes turbulence and ocean currents. she joins me from seattle. all right. lets get right into this question of the drift, kathleen. how does the oceanic drift and the weather factor...
