Not to lessen the clip any, but I think this wasn't a big surprise to many people. What is a surprise (to me) is that they are again attempting to confirm this. Not a revelation, however, it's understandable that they needed sufficient data to prove it.

Thanks for sharing this clip Invictus.

And the density of the rock beneath the seafloor shifted, producing detectable gravity changes.</DIV></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/3C7025D5-9603-4A22-982B-3812E69EC666/blog/" title="blog or email this clip"><img src="http://content8.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
