By Winston Ross, The Register-Guard, Eugene, Ore. Jun. 13--West Coast groundfishermen can expect a major change in the way they're allowed to catch fish in the coming years, after a preliminary decision Thursday from the Pacific Fishery Management Council. The council voted in favor of an individual quota system that will determine who gets to catch how many fish. Shares of the resource will be allocated, and can be traded, sold or kept for life. The decision isn't final unless...

Fishery biologist Sandy Sutherland looks through the lens of the microscope at tiny sections of fish earbones, known as otoliths, each showing annual bands of growth. She carefully counts the bands to determine the age of the fish, then moves on to the next sample.  Known as an age reader, Sutherland is one of a small team at NOAA's Northeast Fisheries Science Center (NEFSC) whose aging work is critical to stock assessments needed to manage the nation's fishery resources in the Northwest...

RV Polarstern finished first Antarctic field season within the International Polar YearThe Antarctic deep sea gets colder, which might stimulate the circulation of the oceanic water masses. This is the first result of the Polarstern expedition of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association that has just ended in Punta Arenas/Chile. At the same time satellite images from the Antarctic summer have shown the largest sea-ice extent on record. In the...

Federal research minister aboard the research icebreaker PolarsternIn the Southern Ocean, large quantities of surface-drifting plankton algae are able to significantly reduce the carbon dioxide content of the surface waters, which can affect the global carbon dioxide cycle. This is one of the results from an Antarctic expedition which has just drawn to a close in Cape Town on February 4, and which was led by the Alfred Wegener Institute, part of the Helmholtz Association. On February 5, an...

GRANTS PASS, Ore. -- At a time when a quarter of the world's fisheries are considered depleted, can commercial fishermen make more money by fishing less? A study published in the Friday edition of the journal Science says they can - with one condition. They must be in a cooperative fishery, like those operating in New Zealand and Australia, where individual fishermen own a share of the total harvest rather than the competitive fisheries more common in the United States, where it's a race to...

By RANDOLPH E. SCHMID WASHINGTON - Undersea explorer Robert Ballard leans back and smiles at the screens arrayed above his desk. One displays a view of a remote operating vessel, another scans along a seafloor never before viewed by humans. It's the Black Sea, not far from Ukraine, a region long closed to outsiders and now yielding a treasure trove of Byzantine vessels that met their ends 1,000 or more years ago. For Ballard the archaeologist, those vessels and their contents are a...

By MICHAEL OLIVEIRA (CP) - They look like something out of a sci-fi horror movie: slimy, snake-like creatures with sharp-toothed tongues that like nothing more than to suck blood. They've stalked the Great Lakes since the 1800s, leaving scores of dead in their wake, and even the best science hasn't been able to stop their incessant breeding. Scientists have mapped their genome, are experimenting with cutting-edge pheromone research and sterilization techniques, and have pulsed the...

PARIS (Reuters) - Pirate trawlers will be tracked by a new database as part of a planned crackdown on illegal fish catches worth $9.5 billion a year that are adding to strains on global stocks, an international report said on Friday. The so-called High Seas Task Force, comprising six governments and three conservation organizations, also urged tighter rules for trawlers, better monitoring of marine stocks and improved international cooperation to catch pirates. "Illegal, unreported...

By Irwin Arieff UNITED NATIONS (Reuters) - The UN General Assembly urged governments and fisheries management groups on Monday to take urgent steps to protect endangered sea turtles and sea birds from an indiscriminate fishing technique. A resolution adopted by consensus by the 191-nation assembly is aimed at restricting a form of industrial fishing known as longline fishing. It is used by large fishing vessels in the Pacific Ocean that trail lines studded with hooks that can...

DURHAM, N.C. -- Duke University oceanographers have developed an explanation for why a vast North Atlantic circulation zone can have a large variability in nutrient supplies needed to sustain ocean plants and, by extension, support the food web of marine life. The circulating zone in the North Atlantic Ocean, known as a "subtropical gyre," swirls in a clockwise direction between the Gulf Stream -- the warm current that bisects the Atlantic between the southern U.S. and northern Europe -- and...

Ocean Analysis for November 17, 2012

Point #1: Warm finger- This region inside the area marked number 1, represents a warm finger of the ocean temperatures. What is occurring is that the warmer air is being pushed faster in this region than the surrounding locations giving us this little finger of warmer temps in that region. Point #2: Warm Eddie- This is a region of warmer temps surrounded on all sides by colder water. Eddies are a closed circulation of water in the ocean that has in this case warmer temps around it. These...

Ocean Current Impacts On Weather

The Peru Current flows from South to North along the western side of South America. This current transports colder air from the south northward towards the equator. This current is responsible for bringing cooler waters off the coast of Peru which is a big reason that they have such high fishing success. However this current can get altered during EL-Nino when the warmer waters of the Pacific are transported west to east and start to replace these colder waters. The Peru current is...
