Scientists Uncover Deep Ocean Current Near Antarctica Last Updated on 2010-04-24 00:00:00 SINGAPORE (Reuters) - Scientists have discovered a fast-moving deep ocean current with the volume of 40 Amazon Rivers near Antarctica that will help researchers monitor the impacts of climate change on the world's oceans. A team of Australian and Japanese scientists, in a study published in Sunday's issue of the journal Nature Geoscience, found that the current is a key part of a global ocean circulation pattern that helps control the planet's climate. Scientists had previously detected evidence of the current but had no data on it. "We didn't know if it was a significant part of the circulation or not and this shows clearly that it is," one of the authors, Steve Rintoul, told Reuters. Rintoul, of the Antarctic Climate and Ecosystems Cooperative Research Center in Hobart, said it proved to be the fastest deep ocean current yet found, with an average speed of 20 cm (7.9 inches) a...

UCSD Working To Build Ocean Observation System Last Updated on 2009-09-02 00:00:00 UC San Diego is part of a partnership that is working to construct a network of ocean observation systems. Called the Ocean Observatories Initiative, the system will allow scientists to examine ocean processes on global, regional and coastal scales. The National Science Foundation and the Washington, D.C.-based Consortium for Ocean Leadership signed an agreement Wednesday that spports the construction and initial operation of the system.   In collaboration with Ocean Leadership, UC San Diego is slated to receive a total of approximately $32 million to develop and construct the science-driven, networked cyberinfrastructure, which ties together all the ocean sensors to be put to work during the next five years. Scripps Institute of Oceanography Professor John Orcutt said the system will give scientists the infrastructure to conduct experiments in some of the ocean's most...

Part of vast ocean observing network will be in Newport Last Updated on 2009-09-02 00:00:00 Not long after landing the Pacific fleet of the National Oceanic and Atmospheric Administration, Newport is getting another feather in its cap. The coast city will soon be home to one piece of a $386 million world-wide ocean observing network announced today. Oregon State University researchers will spend$14 million over the next five years to create a network of surface moorings, seafloor platforms and undersea gliders in the Pacific Ocean off the coast of Newport and Grays Harbor, Wash. "This project will be transformative in that our ability to observe and monitor the ocean will be constant - 24 hours a day instead of the episodic nature of a week at sea here and there," said Mark Abbott, dean of OSU's College of Oceanic and Atmospheric Sciences. The sites in the Northwest are just one part of a global observation network called the Ocean Observatories... More »
How jellyfish may be stirring the ocean Last Updated on 2009-07-29 00:00:00 A new study suggests the movement of masses of tiny marine creatures could have as much impact as the wind or currents on ocean circulation. Winds do it. Ocean currents do it. And now, it looks like tiny marine creatures can do it too – act collectively as a giant Mixmaster, bringing cold, nutrient-rich water from deep in the ocean to the surface, where other marine life can use the nutrients. A pair of aeronautic scientists say they have shown how marine organisms ranging in size from tiny copepods to shrimp-like krill to jellyfish – known collectively as zooplankton – could play a vital role in stirring up the ocean. If they’re right, marine organisms of all sorts may be responsible for as much deep-water mixing as winds and currents. And that could have implications for conservation concerns ranging from the health of fisheries to the unanticipated effects from climate change... More »
