Oceanographers have completed an important step in constructing the first deep-sea observatory off the continental United States. Workers laid 32 miles of cable along the Monterey Bay sea floor that will provide electrical power to scientific instruments, video cameras, and robots 3,000 feet below the ocean surface. The link will also carry data from the instruments back to shore, for use by scientists and engineers from around the world, reports the National Science Foundation. The Monterey Accelerated Research System (MARS) observatory, due to be completed later this year, will provide ocean scientists with 24-hour-a-day access to instruments and experiments in the deep sea. The project is managed by the Monterey Bay Aquarium Research Institute and funded by the National Science Foundation. Currently, almost all oceanographic instruments in the deep sea rely on batteries for power and store their data on hard disks or memory chips until they are brought back to the surface. With a continuous and uninterrupted power supply, instruments attached to the MARS observatory could remain on the sea floor for months or years.

The cable itself contains a copper electrical conductor and strands of optical fiber. The copper conductor will transmit up to 10 kilowatts of power from a shore station at Moss Landing, California, to instruments on the sea floor. The optical fiber will carry up to 2 gigabits per second of data from these instruments back to researchers on shore, allowing scientists to monitor and control instruments 24 hours a day, and to have an unprecedented view of how environmental conditions in the deep sea change over time. “After 5 years of hard work, we are thrilled to bring the age of the Internet to the deep ocean, so we can understand, appreciate and protect the two-thirds of our planet that lies under the sea,” said MBARI director Marcia McNutt. —Julia Whitty

We've never been very good at being conservative.

And usually, that serves us well in doing the ambitious, hard-hitting journalism that you turn to Mother Jones for. But it also means we can't afford to come up short when it comes to scratching together the funds it takes to keep our team firing on all cylinders, and the truth is, we finished our budgeting cycle on June 30 about $100,000 short of our online goal.

This is no time to come up short. It's time to fight like hell, as our namesake would tell us to do, for a democracy where minority rule cannot impose an extreme agenda, where facts matter, and where accountability has a chance at the polls and in the press. If you value our reporting and you can right now, please help us dig out of the $100,000 hole we're starting our new budgeting cycle in with an always-needed and always-appreciated donation today.
