One 55- Gallon Barrel found in Atlantic Ocean?

DARPA to engage Applied Mathematics, Computer Science and Data Visualization communities to develop “big data” analytics and usability solutions for warfighters...
“The sheer volume of information creates a background clutter…,” said DARPA Acting Director, Kaigham J. Gabriel. “Let me put this in some context. The Atlantic Ocean is roughly 350 million cubic kilometers in volume, or nearly 100 billion, billon gallons of water. If each gallon of water represented a byte or character, the Atlantic Ocean would be able to store, just barely, all the data generated by the world in 2010. Looking for a specific message or page in a document would be the equivalent of searching the Atlantic Ocean for a single 55-gallon drum barrel.”
