By Steve Connor14 December 2011 Dramatic and unprecedented plumes of methane – a greenhouse gas 20 times more potent than carbon dioxide – have been seen bubbling to the surface of the Arctic Ocean by scientists undertaking an extensive survey of the region. The scale and volume of the methane release has astonished the head […]
By HIROKO TABUCHI and MARTIN FACKLER4 December 2011 TOKYO — At least 45 tons of highly radioactive water have leaked from a purification facility at the Fukushima Daiichi nuclear power station, and some of it may have reached the Pacific Ocean, the plant’s operator said Sunday. Nearly nine months after Fukushima Daiichi was ravaged by […]
By David A Gabel, ENN28 November 2011 As Earth’s climate has warmed, one group of species that has not fared well has been corals, the sedentary marine species which lives symbiotically with algae. Warmer waters cause the algae to become heat-stressed, causing them to die or be expelled by the coral. This causes coral bleaching, […]
Relative composition of the periphytic diatom assemblages along the CO2 gradient, including all genera present over 1% and with all unidentified diatoms grouped as unidentified pennate or naviculoid. Between September 2009 and October 2010, mean surface seawater pH decreased with increasing proximity to CO2 vents (S1 = 8.18, S2 = 8.05, S3 = 7.49, n […]
November 23 (Science Daily) – An analysis in the SEI journal Climate and Development predicts severe negative impacts, including loss and alteration of habitats, smaller and less-diverse fish stocks, and coral bleaching, and urges prompt action to help the Caribbean fisheries prepare. The review, “The implications of global climate change for fisheries management in the […]
By Michelle Esteban 11 November 2011 SEATTLE – Debris the size of California is headed for the U.S. coast. The materials were swept out to sea after a massive earthquake and a tsunami hit Japan last March. A local oceanographer says while the bulk of the debris will take several years to arrive, items that […]
By Jake Ellison 3 November 2011 Calling it an “emerging threat,” Sen. Maria Cantwell testified in congress yesterday that a floating debris field five-times the size of the state of Washington is heading for the West Coast and could disrupt the state’s economy when it lands in 2014. “After the tragic tsunami that struck Japan, […]
[Translated from French] This graph shows the evolution of sampled cesium-137 concentration and the respective distance from the Fukushima Daiichi nuclear plant. Concentrations vary typically from 1 to 10,000 Bq/kg, with an increasing trend over time. This evolution may be the result of the kinetics of cesium transfer to sedimentary particles and particle deposition processes […]
From Jiji Tsushin (10/28/2011): フランス政府系の放射線防護原子力安全研究所（ＩＲＳＮ）は２７日、東京電力福島第１原発事故後の３月２１日から７月半ばまでに海に流出した放射性セシウ ム１３７の総量は２．７１京ベクレル（１京は１兆の１万倍）で、東京電力が６月に発表した推計値の２０倍に達すると推定した調査報告書を公表した。 On October 27, the Institute for Radiological Protection and Nuclear Safety (L’Institut de Radioprotection et de Sûreté Nucléaire, IRSN) of France announced its research report in which the researchers estimated the total amount of radioactive cesium-137 leaked from Fukushima I Nuclear Power Plant into the ocean was 27,100 terabecquerels […]
Contact: Elisabeth (Lisa) Lyons, elyons@cell.com 617-386-212127 October 2011 As the planet continues to warm, it appears that seaweeds may be in especially hot water. New findings reported online on October 27 in Current Biology, a Cell Press publication, based on herbarium records collected in Australia since the 1940s suggest that up to 25 percent of […]
