Tensions Between Archivists and 'Occupy' Protesters Over Preserving the Movement 153

Posted by samzenpus from the high-water-mark dept.
An anonymous reader writes "At one point an NYU librarian literally got into a shouting match with a protester at an Occupy protest, trying to make the case for why a digital record should be kept of photos, videos, audio recordings, posters, and other materials, so future scholars and activists can recount what happened. Academics are taking unusual steps to preserve the protesters' stuff, including 'distributing postcards promoting archiving at protests, developing automated systems to download photos posted online, and asking participants to vote on which images are most important for the historic record.'"

New Estimates Say Earth's Oceans Smaller Than Once Believed 263

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."
