Seraphina said:It is the rover moving and stirring up the dust.
Was anyone able to read a date/time stamp on the video?
Gonzo said:It seemed clear to me the sea floor swelled and then dropped. I thought that seemed pretty obvious, but if others don't see it the same way, I will assume my mind was playing tricks on me, perhaps affected by the overly zealous narrator.
Gonzo said:What movement do you think it did to kick up so much debris?
newsweek said:ROVs range in size depending on their intended use, but a really large one could be the size of a UPS truck, says Cameron Wallace, director of marketing and investor relations at Helix Energy Solutions Group, one of the companies currently operating ROVs for BP’s spill response efforts.
Gonzo said:Salut, Laurentien.
Are those coordinates from the geolocation service used by the camera?
Thanks,
Gonzo
Laurentien said:If you look at the top of the picture you see the compass doesn't move until the ground start moving, it point to the south all the time except of some fluctuation east and west during the rising and cave in. As well, if you look at the ground coordinate, upper left, it doesn't show any movement until the arm rise at the end, after the motion of the see floor as set and sediment are lifted. That show that someone moved the rover and it is showed on the coordinate that start changing til the end of the video.
By the way I checked the coordinate from this video and the coordinate on this one http://www.youtube.com/watch?v=vMqHldEHL64&feature=player_embedded#! posted by Laurentiu. They are very close here they are;
this one: E 1202826.03
N 10431469.21
Laurebtiu: E 1202799.01
N10431610.00
Seraphina said:the compass doesn't move much until after the ground moves up and down, but the DPT (depth) and ALT (altimeter) do, then the compass is fluctuating S to SW to S to SE back to S a bit then moves a lot to E....just seems to me that the force exerted to move the seafloor would have produced enough shockwave to send the rover reeling, if it was in fact the seafloor moving and not the rover itself. As the rover scrapes along the floor it stirs up the sediment and whirls around in the turbulence from the rover and its propulsion.
Here's a video of a rover in action...they don't show it moving up and down, but they do explain how it's done at the end. If I can find another example, I'll post it.
From article said:WASHINGTON – With a startling report that some researchers call more spin than science, the government said Wednesday that the mess made by the BP oil spill in the Gulf of Mexico is mostly gone already...
...Nevertheless, Wednesday was a day of cautious celebration by a White House that has had little to cheer about from the oil spill.
"I think it is fairly safe to say ... that many of the doomsday scenarios that we talked about and repeated a lot have not and will not come to fruition," White House spokesman Robert Gibbs said at a briefing with NOAA's top scientist.
Much of the reasoning behind the disappearing oil has to do with the natural resilience of the Gulf, which is teeming with microbes that eat oil. On top of that is the natural tendency of oil in seawater to evaporate and dissolve to half its volume in about a week — something even critics acknowledge.
The federal calculations are based on direct measurements for only 18 million gallons of the oil spilled — the stuff burned and skimmed. The other numbers are "educated scientific guesses," said NOAA emergency response senior scientist Bill Lehr, an author of the report. That is because it is impossible to measure oil that is dispersed, he said.
