'Transponders' from Japan was ashore along US West Coast
September 26, 2014 06:37 AM - Oregon State University
Northwest anglers venturing out into the Pacific Ocean in pursuit of salmon and other fish this fall may scoop up something unusual into their nets — instruments released from Japan called "transponders." These floating instruments are about the size of a 2-liter soda bottle and were set in the ocean from different ports off Japan in 2011-12 after the massive Tohoku earthquake and tsunami. Researchers from Tattori University for Environmental Studies in Japan have been collaborating with Oregon State University, Oregon Sea Grant, and the NOAA Marine Debris Program on the project.
A concrete idea: MIT develops better, greener, concrete
September 25, 2014 01:06 PM - David L. Chandler, MIT News Office
Concrete is the world's most-used construction material, and a leading contributor to global warming, producing as much as one-tenth of industry-generated greenhouse-gas emissions. Now a new study suggests a way in which those emissions could be reduced by more than half - and the result would be a stronger, more durable material. The findings come from the most detailed molecular analysis yet of the complex structure of concrete, which is a mixture of sand, gravel, water, and cement. Cement is made by cooking calcium-rich material, usually limestone, with silica-rich material - typically clay - at temperatures of 1,500 degrees Celsius, yielding a hard mass called "clinker." This is then ground up into a powder. The decarbonation of limestone, and the heating of cement, are responsible for most of the material's greenhouse-gas output.
Goats found to be better than chemicals when it comes to curbing invasive marsh grass
September 25, 2014 01:01 PM - Duke University via EurekAlert!
Herbivores, not herbicides, may be the most effective way to combat the spread of one of the most invasive plants now threatening East Coast salt marshes, a new Duke University-led study finds. Phragmites australis, or the common reed, is a rapid colonizer that has overrun many coastal wetlands from New England to the Southeast. A non-native perennial, it can form dense stands of grass up to 10 feet high that block valuable shoreline views of the water, kill off native grasses, and alter marsh function.
Seattle Assesses Fine for Wasting Food
September 25, 2014 09:01 AM - Jan Lee, Triple Pundit
The push for increased sustainable methods can be seen everywhere these days — certainly when it comes to local efforts to pare down on what we toss in the landfill. The city of Seattle has also embraced the composting idea with a bit more of a creative edge: In an effort to encourage residents to stop wasting food, the city council passed an ordinance this last Monday that allows households to be fined $1 each time that garbage collectors find more than 10 percent of organic waste in their garbage bins.
Amazing maps of what Antarctica looks like under all that ice
September 25, 2014 08:01 AM - British Antarctic Survey
New maps of the sub-ice features in Antarctica and the Arctic, featured in the new edition of The Times Comprehensive Atlas of the World published on 25 September 2014, reveal an unseen world of canyons, lakes, trenches and mountains. The 14th edition of the Atlas also includes a new double page map of the Arctic Ocean, which highlights the dramatic long-term decline of Arctic sea ice cover. The sub-ice maps draw on bedrock data, provided by the British Antarctic Survey, to show physical features which are obscured by ice cover. In the Antarctic, one of the most striking features is the Gamburtsev Subglacial Mountains, which are as large as the Alps but are currently completely covered by ice.
A new treaty to restore Buffalo herds and grazing land
September 24, 2014 01:29 PM - Wildlife Conservation Society
This week, dignitaries from U.S. Tribes and Canadian First Nations signed a treaty-the first among them in more than 150 years-to establish intertribal alliances for cooperation in the restoration of American buffalo (or bison) on Tribal/First Nations Reserves or co-managed lands within the U.S. and Canada. This historic signing of the "Northern Tribes Buffalo treaty" occurred in Blackfeet territory in Browning, Montana, and brought together members of the Blackfeet Nation, Blood Tribe, Siksika Nation, Piikani Nation, the Assiniboine and Gros Ventre Tribes of Fort Belknap Indian Reservation, the Assiniboine and Sioux Tribes of Fort Peck Indian Reservation, the Salish and Kootenai Tribes of the Confederated Salish and Kootenai Indian Reservation, and the Tsuu T’ina Nation.
Chinese Now Emit More Carbon Per Capita Than Europeans
September 24, 2014 09:39 AM - Jeremy Hance, MONGABAY.COM
Last year, the people of China emitted more carbon per person than those in the EU, according this year's Global Carbon Budget. The report, updated annually, also found that global emissions jumped 2.5 percent last year and are set to hit a record high of 40 billion tonnes this year. The findings highlight how little global society has done to stem emissions, despite numerous pledges and past global agreements.
Whooping Cranes being raised and released by the US Geological Survey
September 24, 2014 07:51 AM - USGS Newsroom
Four whooping crane chicks raised in captivity began their integration into the wild Saturday as part of the continuing effort to increase the wild population of this endangered species. The cranes, hatched and raised by their parents at the U.S. Geological Survey's Patuxent Wildlife Research Center in Laurel, Maryland, were released on the U.S. Fish and Wildlife Service's Necedah National Wildlife Refuge in Wisconsin.
Encouraging planting trees will sequester carbon and conserve habitat
September 23, 2014 04:00 PM - Oregon State University
Rewarding landowners for converting farmland into forest will be key to sequestering carbon and providing wildlife habitat, according to a new study by Oregon State University and collaborators. Current land-use trends in the United States will significantly increase urban land development by mid-century, along with a greater than 10 percent reduction in habitat of nearly 50 at-risk species, including amphibians, large predators and birds, said David Lewis, co-author of the study and an environmental economist in OSU's College of Agricultural Sciences.
The important role that agroecological farming can play to feed the world
September 23, 2014 11:02 AM - Nafeez Ahmed, The Ecologist
Governments must shift subsidies and research funding from agro-industrial monoculture to small farmers using 'agroecological' methods, according to the UN's Special Rapporteur on the Right to Food. And as Nafeez Ahmed notes, her call coincides with a new agroecology initiative within the UN's Food and Agriculture Organisation. This is critical for future agricultural policies. Currently, most subsidies go to large agribusiness. This must change. Governments must support small farmers. Modern industrial agricultural methods can no longer feed the world, due to the impacts of overlapping environmental and ecological crises linked to land, water and resource availability.
