>> ammann, keep us posted. thank you so much. other news now turning to the missing malaysian flight 370. searchers will now send out a sophisticated submarine to visually find the wreckage. they are deployed the unmanned bl bluefin-21. it's been six days since sounds were detected. the equipment sending out the signals may have now run out of battery life. they continue with planes and ships. an oil slick detected yesterday but the search of air and sea surface will end in two to three days. katy tur joins us from perth, australia, with more. katy, good morning. >> reporter: hey, there, wil...

We're hearing about bluefin 21, it's going on. should we be optimistic, ooh, we're moving on or the other possibility? >> i'm very optimistic about what they found, that two-mile stretch where they got that pinger for is where they're going to focus that bluefin 21. >> hence, the rebirth and renewal theme of the colors you have on today. mary schiavo, the oil slick that they found in the area, we hear that they're not going to be looking for debris anymore because they believe the length of time is too long to find out. but then they find this slick. could it be connected? what are the chances...

Quite a large underwater search area was determined on the basis of the exchanges between the satellite, the inmarsat satellite and the aircraft, the handshakes. and you might remember, we had the seventh ping. this area that we're in is under where the seventh ping occurred. now, after that analysis was done, that enabled the deployment of "ocean shield" with the pinger, pinger locator and she went into that area and she received transmissions from the deep. that is the basis, the four transmissions taken together are the basis for the underwater search area. okay? >> what more do we know abo...
