Meters down and it triggered a safety mechanism which said i m too deep below my operating maximum. it went back up to the surface after only six hours of going along the bottom and mapping that surface with the side-scan s sonar. they will be analyzing the data and sending it back down soon. it is a very laborious process. but this one is cut short. one interesting observation, the ships searching for debris on the surface, 200 to 300 miles to the west of where the bluefin is operating they turned and headed south in the last 24 hours or so. they are looking for debris on the surface. ....

More about the surface of the moon than the ocean floor in that part of the indian ocean. now the bluefin-21 went down there. the best guess that they had was that the ocean floor might be 42 to 4400 meters down. well, the blue fin got to 4500 meters down, and that triggered an internal mechanism, a safety mechanism, if you like, in the blue fin, which said i m too deep, i m below my operating maximum, i have to go back up to the surface. it went back up to the surface after only six hours of going along the bottom and starting to map that surface with its side scan sonar, back to the top they ve been downloading the data and analyzing it. and they ll be sending it back down soon. it is, as we ve reported all along, a very laborious process, about 15.5 square miles on each of these trips. one other interesting observation, the ships that have ....

you see species down there you don t see anywhere else. all sorts of life forms, you don t see underwater rivers what is an underwater river. it is density, water moves because it is dense, if it is salty or cold, the water is actually water that cuts across the sea bed. of water that is more dense? yeah, it floats, it started to use the antarctic and pours into the basins, where it comes up against a steep cliff, it makes a waterfall. the lakes are even more amazing that you can go to the bottom of the ocean and see what looks like a lake at night. would it interfere with the towed pinger locators? potentially it could, it makes a little bit of extra noise, there are some that are in that frequency range. there is the physical movement of the propeller and pieces on it that can interfere. it should be distinguishable, but as the battery gets weaker and weaker, they want it as quiet as possible down there. the side sonar scanner, i think it is called bluefin, how de ....
