Archimedes' principle states that the bouyant force on a submerged object is equal to the weight of water that it displaces. Average rock density is around 200-250 pounds per cubic foot. Sea water is around 64 pounds per cubic foot. Therefore an average rock submerged in sea water will have an effective density of 136 to 186 pounds per cubic foot, or 64 pounds per cubic foot less than in air. About a 30% reduction.

Wow, That much? Thanks for doing the math, JonF. I wasn't even in the ballpark.

Now let's get serious for one moment: How porous is porous? These aren't soapstones you know!

We forgot the woodpeckers too Nermal!

Quotes:- Everything I need to know about life, I learned from Noah's Ark...

1: Don't miss the boat.

2: Remember that we are all in the same boat.

3: Plan ahead. It wasn't raining when Noah built the Ark.

4: Stay fit. When you're 600 years old, someone may ask you to do something really big.

5: Don't listen to critics; just get on with the job that needs to be done.

6: Build your future on high ground.

7: For safety's sake, travel in pairs.

8: Speed isn't always an advantage. The snails were on board with the cheetahs.

9: When you're stressed, float a while.

10: Remember, the Ark was built by amateurs; the Titanic by professionals

Very good! Gave me chuckle, it did.

I am eagerly awaiting the results of the latest fool's errand up the north face of Ararat, due to sally forth this July. I am all but certain that there will be many amazing discoveries that will be presented with no concrete evidence beyond some dubious and possibly 'improved' photographs.

I am in the process of rebuilding my bullshit detector -- it has taken something of a beating, lately -- to deal with all of the marvelous retoric soon to be laid upon us.

doov youv'e just joined the Task Force. Wait till they bring back 'evidence' of their Samharkand Sampan; it's going to be the greatest bullshit 'Turkey Shoot' for a while. I cannot wait either.

Does any one know what satellite was used to take that picture of the "Ark"?

Here is a brief overview I posted on NAIG when the loonies first began talking up the image.

"Reality check – the picture is credited to Digital Globe. DG’s Quickbird 2 imaging satellite has pretty good multi-spectral resolution for a commercial vehicle, up to 2.5m/pixel under ideal circumstances (highest commanded magnification, sun angle, orbital inclination to target, etc.). Typical is 4-6m per pixel, or much less for standard commercial imagery. Even the low quality representation of the photo on the web page (typically compressed by a factor of 10 at least from the actual megapixel sized downlinked photo) shows the object in the circle occupying a space approx. 20x20 pixels. In other words, the object shown AT BEST is 50m x 50m; realistically the “brown object� in the photo is probably 500m x 500m.

Now note that the Trinity corporation claims the object in the red circle is 45 feet high and 75 feet wide and up to 450 feet long (14 by 23 by 138 meters). This would equate to a photo under ideal conditions of 5 pixels by 9 pixels. Tell me, how did Trinity manage to better the laws of physics and digital optics? And just how much detail do you think you can see in 5x9 pixels of a megapixel sized shot?"

- O.A.

I thought I'd balance it up a bit (My excuse to keep the thread live) by giving you this quaint site. The kid's humour is great- 'no batteries included' etc. Yeah, dildos didn't have motors in those days either!!!

http://arksearch.com/

Eg. ' "How did Noah and his family keep busy on the Ark for forty days and forty nights?"
"They held three- and four-legged races." Georgio, age 9
"The same things as they do on the Norwegian Carnival boats you see on TV, except they couldn't stay outside and get tans." Christopher, age 10
"The family did something easy like play Scrabble, and the animals played polo." Roberta, age 8' I think the kids beat the parents every time.

Enjoyable site, I recommend a quick shuftie- no biodiversity criticisms though, they'll have to improve on that one or else their whole argument will be scuppered forever.
