Latest Tagging of Pacific Predators Stories
One of the richest ecosystems in the world, the California Current System, is driven by nutrient input from coastal upwelling and supports a great diversity of marine life. It is also heavily impacted by human activities, much like other coastal regions.
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.
The majestic leatherback turtle is the largest sea turtle in the world, growing to more than 6 feet in length. It is also one of the most threatened. A major new study of migration patterns has identified high-use areas—potential danger zones--in the Pacific Ocean for this critically endangered species.
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.
Ian Jonsen, a research associate and adjunct professor in the Department of Biology at Dalhousie University and co-lead investigator of the Future of Marine Animal Populations Project (FMAP), has teamed up with Barbara Block at Stanford University and several other American researchers to conclude a two year study entitled, "Tracking apex marine predator movements in a dynamic ocean" published in the science journal Nature released June 22.
Satellite tracking of olive ridley sea turtles off the coast of Central Africa has revealed that existing protected areas may be inadequate to safeguard turtles from fishing nets.
Tagging and tracking leatherback sea turtles has produced new insights into the turtles' behavior in a part of the South Pacific Ocean long considered an oceanic desert.
Leatherback turtles are remarkably versatile divers.
Biologging â€“ the use of miniaturized electronic tags to track animals in the wild â€“ has revealed previously unknown and suprising behaviors, movements, physiology and environmental preferences of a wide variety of ocean animals.
The Northern Elephant Seal (Mirounga angustirostris) is one of two species of elephant seal (the other is the Southern Elephant Seal). It is a member of the Phocidae ("true seals") family. Elephant seals get their name from their great size (the Southern Elephant Seal is the larger of the two species) and the fact that the adult males have a large proboscis, which is used in making extraordinarily loud roaring noises, especially during the mating season. There is a great sexual dimorphism...
