Autonomous underwater vehicle of the Alfred Wegener Institute dives under the Arctic ice for the first time The Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association for the first time sent its Autonomous Underwater Vehicle (AUV) on an under-ice mission at about 79° North. The four-metre-long, torpedo shaped underwater vehicle was deployed from the research icebreaker Polarstern under heavy pack ice. The vehicle was subsequently recovered by helicopter. "We...

Even in the dark abyss of the deep ocean animal communities can undergo rapid, widespread and radical changes. Scientists at the National Oceanography Centre are at the forefront of monitoring these changes and understanding the mechanisms responsible. Their latest research is published in a special issue of the journal Deep Sea Research II. We often think of the deep ocean floor as stable, relatively unvarying environment untroubled by surface climate conditions. But long-term monitoring has...

Seven-year experiment shows that pond communities bear a lasting imprint of random events in their past Scientist Jon Chase once worked in a lab that set up small pond ecosystems for experiments on species interactions and food webs. "We would try to duplicate pond communities with a given experimental treatment," he says. "We put 10 of this species in each pond, and five of these species, and eight of the other species, and 15 milliliters of this nutrient and 5 grams of that and 'sproing,'...

Pew Environment Group Urges U.N. to Correct Course NEW YORK, May 24 /PRNewswire-USNewswire/ -- As the United Nations meets to discuss the state of high seas fisheries management, two independent, peer-reviewed studies reveal that ineffective international management is undermining the future of high seas fisheries, fish populations and the health of marine ecosystems. One study -- published online by the journal Science -- finds that governments have been ineffective in stopping illegal...

A new, less selective approach to commercial fishing is needed to ensure the ongoing productivity of marine ecosystems and to maintain biodiversity, according to a paper in the Proceedings of the National Academy of Sciences of the United States of America. The paper, "ËœEcosystem-based fisheries management requires a change to the selective fishing philosophy', was written by a team of authors led by Shijie Zhou of the CSIRO Wealth from Oceans Flagship. Dr Zhou says ecosystem-based...

A team of Spanish and French researchers has undertaken a pioneer analysis of red coral populations in the oldest Marine Protected Areas (MPA) in the Mediterranean and the impact that fishing activity has had. Results show that MPAs are a guarantee for conserving this species. Mediterranean red coral (Corallium rubrum) has been highly valued for jewelry since ancient times. But intensive fishing, particularly in shallow waters, has transformed populations and hindered the recovery of this...

The UK trawl fishing fleet has to work 17 times harder to catch the same amount of fish today as it did when most of its boats were powered by sail, according to new research. Researchers from the University of York and the Marine Conservation Society (MCS) used UK Government data on the amount of fish caught and the size and number of boats involved "“ the fleet's fishing power "“ to analyze the change in fish stocks since 1889. They found that trawl fish landings peaked in...

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...
