At the annual meeting of American Association for the Advancement of Science (AAAS) this Sunday, a Stanford professor discussed a new method for “biologging” the activities of various sea creatures using oceanic "WiFi hotspots" technology.
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 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.
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.
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. All three species of bluefins have seen their population plummet in the past 50 years.
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.
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.
