Scientists have had a remarkable close-up encounter with a gigantic underwater avalanche. It is the first time researchers have had instruments in place to monitor so large a flow of sediment as it careered down-slope. The event occurred in Monterey Canyon off the coast of California in January. Read more
The planet Mars has a moon named Deimos, so it seems only appropriate that the ocean observatory MARS in Monterey Bay have its own DEIMOS. This DEIMOS, however, is an underwater acoustic package designed to monitor movements of fish and zooplankton. MARS, which stands for Monterey Accelerated Research System, consists of a node the size of two compact cars that serves as both a power strip and a high-speed internet connection for scientific instruments. Connected to the California coast by a 35-mile-long cable carrying power and data, MARS went live late last fall 3,000 feet below the surface in Monterey Bay.
Deep-sea observatory goes live Off the coast of Central California, in the inky darkness of the deep sea, a bright orange metal pyramid about the size of two compact cars sits quietly on the seafloor. Nestled within the metal pyramid is the heart of the Monterey Accelerated Research System (MARS)the first deep-sea ocean observatory offshore of the continental United States. Six years and $13.5 million dollars in the making, the MARS Observatory went "live" on Monday, November 10, 2008, returning the first scientific data from 900 meters below the ocean surface. Construction of the observatory was coordinated by the Monterey Bay Aquarium Research Institute (MBARI).
After several larger-scale sea-floor images highlighting tectonic features, Im going to zoom in a bit for todays Sea-Floor Sunday and show you some very cool geomorphological features that develop on the sea floor. What the heck is a cyclic step? Well get to that later first, I want to show a regional map to give you some context. The area well look at in more detail is called the Shepard Meander, a huge meander bend in the Monterey submarine channel. Read more
Oceanographers have completed an important step in constructing the first deep-sea observatory off the continental United States. Workers in the multi-institution effort laid 52 kilometres of cable along the Monterey Bay sea floor that will provide electrical power to scientific instruments, video cameras, and robots 3,000 feet (900 meters) 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. 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 (MBARI) and funded by the National Science Foundation (NSF).
Electricians prefer to keep power cords dry as a rule. But in Monterey, California, scientists and engineers are hopeful that immersing electrical cable off the coast will profoundly improve how the oceans are studied. This week, a team from the Monterey Bay Aquarium Research Institute (MBARI) will lay 52km of electrical cable from a research station on shore to a shelf 900m below the sea's surface. The thick cable will send power to, and return data from, a variety of research instruments - to be added later this year - that will sit on Smooth Ridge, a plateau at the edge of Monterey Canyon, the largest and deepest submarine canyon off the continental West Coast.
