The size of undersea creatures seemed to follow a strange but stable pattern—until industrial fishing came along. On November 19, 1969, the CSS Hudson slipped through the frigid waters of Halifax Harbour in Nova Scotia and out into the open ocean. The research vessel was embarking on what many of the marine scientists on board thought of as the last great, uncharted oceanic voyage: The first compl
The village of Ilulissat in Greenland is seen near the icebergs that broke off from the Jakobshavn Glacier on July 24, 2013. (Joe Raedle / Getty ) There’s a pretty story we tell ourselves about environmental problems: Once you fix them, they immediately start to improve. Smog works like this. In cities where air quality is a problem, smog tends to worsen on weekdays, because millions of people are
1.概要 独立行政法人海洋研究開発機構(理事長 加藤康宏)海底資源研究プロジェクトは、海洋・極限環境生物圏領域およびシステム地球ラボプレカンブリアンエコシステムラボと共同し、2010年9月に行われた地球深部探査船「ちきゅう」による統合国際深海掘削計画(IODP)第331次研究航海(沖縄熱水海底下生命圏掘削シーズン1)で創出した伊平屋北熱水活動域における複数の人工熱水噴出孔について、熱水噴出パターンの変動、熱水化学組成の調査・観測を1年以上にわたり継続し、それらについて明らかにするとともに、海底熱水を持続可能な資源として活用する基盤技術の研究開発を図るため、人工熱水噴出孔に新たに形成されたチムニーの形成様式、組成分析を行いました。 その結果、黒鉱層を形成する海底下の熱水溜まりから直接噴出させた人工熱水噴出孔においては、著しく黒鉱鉱物成分に富んだチムニーが容易に形成され、短期間で大規模に成長す
Deep under the North Atlantic, scientists have discovered a rare system of smoking volcanic vents and three-story "chimneys," according to scientists aboard the research vessel Celtic Explorer. A hotbed of "evolution in overdrive," the site teems with strange animals that have been living there "perhaps for a millennium," said marine biologist Jon Copley. "And we're the first to see this place." T
After Japan nuclear power plant disaster: How much radioactivity in the oceans? by National Science Foundation Among the casualties of the March 11, 2011, earthquake and resulting tsunami in Japan was the country's Fukushima Daiichi nuclear power plant. A result of the loss of electricity, overheating at the power plant led to significant releases of iodine, cesium and other radioisotopes to the e
