Scientists Concerned About Methane, Fishing In Arctic Ocean
2012-04-23 04:04:47

While some scientists encouraged the creation of regulations governing fishing in the Arctic Ocean on Sunday, others published a report warning that the body of water could actually be a significant source of the greenhouse gas methane. The latter team, lead by Eric Kort of the California Institute of Technology (Caltech), participated in a total of five flights to measure atmospheric methane levels in latitudes as high as 82 degrees north in 2009 and 2010, AFP reporters said. They...

Ecologists in New Zealand have shown for the first time that Marine Protected Areas — long advocated as a way of protecting threatened marine mammals — actually work. Their study, based on 21 years' monitoring and published today in the British Ecological Society's Journal of Applied Ecology, reveals that a marine sanctuary off the coast of Christchurch has significantly improved survival of Hector's dolphins — one of the rarest dolphins in the world. Covering 1170 km2 of...

Life deep in the seabed proceeds very slowly. But the slow-growing bacteria living many meters beneath the seafloor play an important role in the global storage of organic carbon and have a long-term effect on climate. A team of scientists from Aarhus University (Denmark) and the University of Rhode Island have developed a new method for measuring this slow life deep down in the seabed. According to URI Oceanography Professor Arthur Spivack, the relative abundance of amino acids that are...

Marine Protected Areas Prove To Be Vital Aspect Of Green Turtle Sustainability
2012-03-21 05:08:51

Ryan Parson for RedOrbit.com Some sea turtles appear to be reaping the benefits of government designated areas of bodies of water, known as Marine Protected Areas (MPAs). A recent study published in the journal Global Ecology and Biogeography suggests that the MPAs are playing a key role in the support and nourishment of the Green turtle. According to the National Marine Fisheries Service, all six species of sea turtles that inhabit US waters are currently listed under the Endangered...

Fishing for a 'balanced harvest' can achieve productive fisheries as well as environmental conservation, an international scientific team reports today in the journal Science. In contrast, increasing fishing selectivity to catch a small group of species and sizes neither maximises production nor minimises the ecological effects of fishing, according to the paper titled, 'Reconsidering the Consequences of Selective Fisheries'. The collaboration that led to the paper was fostered by the...

Unprecedented study also finds fish teeming in fully protected areas Centuries of overexploitation of fish and other marine resources – as well as invasion of fish from the Red Sea – have turned some formerly healthy ecosystems of the Mediterranean Sea into barren places, an unprecedented study of the Mediterranean concludes. Research by an international team of scientists designed to measure the impact of marine reserves found that the healthiest places were in...

To better predict the future, Jack Williams is looking to the past. "Environmental change is altering the composition and function of ecological communities," says the Bryson Professor of Climate, People, and the Environment in the University of Wisconsin—Madison geography department. Williams also directs the Center for Climatic Research in the Nelson Institute for Environmental Studies. On Monday, Feb. 20, Williams is speaking at the annual meeting of the American Association of...

University of British Columbia researchers have identified conservation "hot spots" around the world where the temptation to profit from overfishing outweighs the appetite for conservation. Combining economic outlook and fisheries population growth rates for all countries currently reported to fish in the ocean, UBC fisheries researchers William Cheung and Rashid Sumaila developed a conservation risk index to reveal the economic-conservation trade-offs of fishing. Areas with the highest...

Ocean Analysis for November 17, 2012
2012-11-17 08:24:58

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
2012-07-30 13:25:48

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...
