New Estimates Say Earth's Oceans Smaller Than Once Believed

Velcroman1 writes with this snippet from Fox News: "Using lead weights and depth sounders, scientists have made surprisingly accurate estimates of the ocean's depths in the past. Now, with satellites and radar, researchers have pinned down a more accurate answer to that age-old query: How deep is the ocean? And how big? As long ago as 1888, John Murray dangled lead weights from a rope off a ship to calculate the ocean's volume — the product of area and mean ocean depth. Using satellite data, researchers from the Woods Hole Oceanographic Institute set out to more accurately answer that question — and found out that it's 320 million cubic miles. And despite miles-deep abysses like the Mariana Trench, the ocean's mean depth is just 2.29 miles, thanks to the varied and bumpy ocean floor."

    Typical Amerio-centric head-in-the-sand, the only-reality-is-my-reality bullshit. You realize that you're already using SI units in multiple places in your country? Check food packaging. It's there. It's there in other places too. So you're already using two systems, and it's already been proven that using two sets of units has hazards. "Just ask NASA."

    Never mind the fact that SI units actually work in a sane, base 10 oriented way...

    By every measure I've heard of the earth is supposedly getting heavier

    That's because of the USians.

    I don't trust any of them, but sometimes at least their sources check out. With Fox, there isn't even that decency.

    Mod UP! Because it's true! The IPCC is nothing more then a left-wing scare industry that has been disproven tens of times. (ClimateGate anybody?)
