Liquid Robotics Wave Glider To Track Pacific Great White Sharks
2012-08-18 07:20:34

redOrbit Staff & Wire Reports - Your Universe Online Marine scientists in the US have deployed a surfing robot off the coast of San Francisco in order to help track tagged great white sharks in the Pacific Ocean, various media outlets reported Friday. According to Mark Prigg of the Daily Mail, the seven-foot long robotic "wave glider" was built by Liquid Robotics and resembles a yellow surfboard. It can reportedly detect signals from marked fish up to 1,000 feet away and relay their...

According to new research from the Census of Marine Life Tagging of Pacific Predators (TOPP), two expanses of the North Pacific Ocean are attracting an array of marine predators in predictable seasonal patterns. The new report archives the TOPP program's effort to track top marine predator movements in the Pacific Ocean. The study found major hot spots for large marine predators that exist in the California Current, which flows south along the U.S. west coast, and a trans-oceanic migration...

Scientists advocate solutions and urgent action BOSTON, Mass. "“ Continued mismanagement could force some tuna populations to quickly go the way of cod, a highly threatened fishery that once helped shape economies of whole nations, leading scientists said in the symposium "Last Best Chance for Tuna: Learning from the Cod Collapse" at the American Association for the Advancement of Science (AAAS) Annual Meeting in Boston on February 18. A group of leading natural and social scientists...

Giant bluefin tuna are in trouble, primarily because the powerful muscles that propel their extensive ocean migrations come with an Achilles' heel: They're tasty. Prized by sushi lovers for their savory succulence and by fishermen for the incomparable price they command - one 607-pound fish fetched over $90 per pound at a January auction in Tokyo - all three species of bluefins have seen their population plummet in the past 50 years thanks to worldwide demand. However, there is hope for...

The best oceanographers in the world never studied at a university. Yet they know how to navigate expertly along oceanic fronts, the invisible boundaries between waters of different temperatures and densities. These ocean experts can find rich fishing in places and at depths that others would assume are barren. They regularly visit the most interesting and dynamic parts of the sea. Sea lions, seals, sharks, tuna and other top ocean predators share some of their experiences with human...

Electronic tags broadcasting from the dorsal fins of salmon sharks reveal that these top predators migrate from the glacial waters of Alaska to the warm seas off Hawaii, according to a new study in the journal Science. The salmon shark's ability to survive such a broad range of thermal conditions is attributed to high levels of specialized proteins that keep its heart muscle cells beating at very low temperatures, say the study's authors. "Sharks are declining globally, yet the movements and...
