Zombie greenhouse gas lurks in permafrost beneath the Arctic Ocean

Zombie greenhouse gas lurks in permafrost beneath the Arctic Ocean Nicoletta Lanese © Provided by Live Science The coastline of the Bykovsky Peninsula in the central Laptev Sea, Siberia Millions of tons of organic carbon and methane beneath the Arctic Ocean thaw out and ooze to the surface each year. And climate change could speed up this release of greenhouse gases, new research suggests.  The carbon tied up in organic matter and methane (a carbon atom bound to four hydrogen atoms) are currently trapped in subsea permafrost, which is frozen sediment that became covered by 390 feet (120 meters) of seawater toward the end of the Paleolithic ice age about 1,800 to 1,400 years ago, according to the U. S. Geological Survey (USGS). Most subsea permafrost sits on the continental shelf under the Arctic Ocean, said study author Sayedeh Sara Sayedi, a doctoral student in the department of plant and wildlife science at Brigham Young University in Salt Lake City.

Listen to this post The White River Algae Study is on schedule with all the data collection being complete for the three-year study. The U.S. Geological Survey (USGS) will now analyze all the data they have collected and provide a final report in late 2021. The USGS staff presented an update to the White River Algae Study Technical Advisory Committee (TAG) via a virtual meeting on December 8th. The USGS PowerPoint presentation is available on the White River and Douglas Creek Conservation Districts’ Algae page of their website at www.whiterivercd.com or you can link directly to the presentation by scanning the below ZapCode.

Environmental News Network - Identifying Where to Reforest After Wildfire

Identifying Where to Reforest After Wildfire Details A future of fewer Christmas trees? Conifers expected to decline. In the aftermath of megafires that devastated forests of the western United States, attention turns to whether forests will regenerate on their own or not. Forest managers can now look to a newly enhanced, predictive mapping tool to learn where forests are likely to regenerate on their own and where replanting efforts may be beneficial. The tool is described in a study published in the journal Ecological Applications by researchers from the University of California, Davis; U.S. Geological Survey (USGS), Cal Fire and the U.S. Forest Service.

Hawaiian volcano that obliterated 700 homes in 2018 blasts back into life

Hawaiian volcano that obliterated 700 homes in 2018 blasts back into life 21 Dec, 2020 11:37 PM 5 minutes to read AP By: Caleb Jones A volcano has erupted in Hawaii, spewing lava, boiling a lake dry and sending a massive plume of steam, gas and ash 9000 metres into the sky. Kilauea s strong blast follows a series of earthquakes, including a 4.4-magnitude shake. The blast, which started on Monday, follows warnings that Kilauea is growing more explosive and that a major eruption is imminent. In the first hours of the eruption, lava mixed rapidly with water in the summit s crater lake to create a massive plume of steam. Photo / USGS via AP
