For decades, marine chemists have faced an elusive paradox. The surface waters of the world’s oceans are supersaturated with the greenhouse gas methane, yet most species of microbes that can generate the gas can’t survive in oxygen-rich surface waters. So where exactly does all the methane come from? This longstanding riddle, known as the “marine methane paradox,” may have finally been cracked thanks to a new study from the Woods Hole Oceanographic Institution (WHOI). (more…)

*History of influence of industrial revolution hidden in glacial ice*

New clues about how Earth’s remote ecosystems have been influenced by the industrial revolution have been uncovered. Until now they were locked away, frozen in the ice of glaciers.

So say scientist Aron Stubbins of the Skidaway Institute of Oceanography and colleagues. (more…)
