Help Alaska’s fisheries: Reduce methane emissions

NOAA now confirms that another critical Alaska fishery is in decline due to successive marine heat waves. First there was the loss of 10 billion snow crabs and the close of the once-lucrative Bering Sea crab fisheries; now we know that climate change (warming seas) is the culprit behind the crash of chum salmon on the Yukon-Kuskokwim. Both these fisheries are the life blood to many Alaskan communities and villages. From the Yukon to Kodiak, from the Arctic to Ketchikan, Alaska’s coastal fisheries must now confront the dual threat of heat waves and ocean acidification. more, >>click to read<< By Linda Behnken and Kate Troll 15:48

BP oil spill: methane persisted in sea after microbe cleanup

As much as half a million tonnes of natural gas, 80 percent of it methane, leaked into the deep sea as a result of the blowout on April 20, 2010, on BP’s Deepwater Horizon rig. The leak triggered a surprising “bloom” of marine bacteria that feasted on the gassy hydrocarbon plume.  The bugs did indeed remove a significant amount of the gas, but their population crashed while the leak was still in progress, it said.
