I got my information here.. It turned into a mostly submariners thread...I lurked and learned.
"Remember the bombing of the Chinese embassy in Belgrade..."
Very good point, ETM! It's crazy isn't it...we can drop a bomb down a bunker in Tora Bora or some other obscure mountain pass cave. We probably do satellite snipe hunts on *endangered* critters and spend fortunes doing so but somehow basic defense needs (along with a submariner) were skuttled for lack of resources. We've even landed on one of Saturn's moons for heavens sake!!! Some should be hung out to dry "bigtime" on this. This is beyond the pale.
In '69, I was at Coronado where the inquiry was going on. Saw a lot of beat up and sad sailors from Pueblo. You got it right about the capture but electronics wasn't the big deal. Codeword material was compromised. All codewords were changed overnight once Pueblo was seized. That's memorable.
Good to meet you, Sal.
Like we postulated: seamount and inadequate mapping. I'd surely hate to have to navigate that area submerged with any of the charts I've seen.
Don't have them handy right now, but I bet that National Geographic has better relief maps of the seafloor than these... :-(
Easy on me.... The one just above #4 I had fixed, it works..... That will get you started......
Someone please explain how "satellite data" can do anything but tell you where you are on the face of the earth - and to locate on that same face "known" obstructions.
Sounds to me like someone is expecting GPS to peer under the ocean to see sea-mounts. Not happening.
We need a heavy technology discussion on what radar can do about peering through 1000 feet of water to map the undersea.....
I don't think it can, radar depends on reflection...
MAybe "used to have most accurate" maps.
Al Gore - in re-inventing Govt took an axe to the NOAA Corps (#7 of the 7 uniformed services) and tried to disolve the NOAA Dept altogether. Result, NOAA is forced to contract out ocean mapping and the result 'vary'.
Rainer - the ship that made the mountain famous and the beer that made it possible.
Right!
I think the mid atlantic rift waS MAPPED at great effort....using special equipment (suspended at great depths ) and some kind of sonar...
Viewing the Morphology of the Mid-Atlantic Ridge From a New Perspective
We have:
The nature of the volcanic and tectonic response of mid-ocean ridges to magmatic and rifting processes is a key component in understanding how new ocean crust is created. New high-resolution side-scan sonar images of the axis of the slow-spreading Mid-Atlantic Ridge (MAR) show volcanic constructs and faults and fissures that are similar in size and shape to those observed at well-studied subaerial rift zones such as Hawaii and Iceland. The new information provided by these high resolution side-scan sonar images, combined with swath bathymetric coverage, is now allowing us to apply the terrestrial analogs to the MAR to understand dike emplacement, shallow transport of magma, eruption mechanisms, tectonic strain, and crustal evolution.
These images are changing our ideas about the formation and evolution of slow-spreading crust. They indicate that magmatic pro- cesses at the MAR may be more comparable to those at subaerial rift zones than previously thought. Furthermore, these data are enabling us to design future detailed geophysical and geochemical studies at the MAR at the same scale as used at subaerial rifts.
The Navy needs to get some of this technology....
Ernest, is there any chance this a new formation from the tsunami?
Indianapolis?
Note that the following islands in the Caroline Island chain can be seen on both maps and define the area around the crash site: Lamotrek, Pikelot, Satawal, West Fayu. To effectitvely view these maps, push F-11 on your keyboard.
That is all...
--Boot Hill
Although the article implied that there was prior indication of something there:
But since the accident, Mr. Andreasen said, his office has examined commercially available images taken by a Landsat satellite in 1999, and at least one image indicates that an undersea mountain could rise to within 100 feet of the surface there. Analysts say variations in water color can sometimes indicate a land mass below.
I don't think it can, radar depends on reflection...
Mapping the Seafloor from Outer Space
"The time it takes the energy to return to the satellite is used to measure the distance to the sea surface very precisely (within accuracies of less than an inch!)"
According to this link, and depending on the effects of water temperature and surface currents, a seamount of 1000 feet elevation above the surrounding ocean floor would be reflected in an increase of one foot of the ocean's surface. Don't ask me how they account for the motion in ocean's surface motion unless they take the mean time of the reflected beam after repeated passes of the satellite.
Seems to me that while this accident might not have been directly prevented by an unharassed program, it certainly points to a need for the LFAS program.
(BTW, link provided for reader convenience...not sure about the info on it--it's Federation of American Scientists.)
I think the skipper was driving too fast.
