Vulnerable carbon stores twice as high where permafrost subsidence is factored in, new research finds
Sinking terrain caused by the loss of ice and soil mass in permafrost is causing deeper thaw than previously thought and making vulnerable twice as much carbon as estimates that don’t account for this shifting ground.

Peatlands release more methane when disturbed by roads
Roads built through acidic wetlands may make greenhouse gas emissions from the wetlands spike by damming natural water flow, according to a new study in AGU’s Journal of Geophysical Research: Biogeosciences.

Leafcutter ant colonies may be an overlooked source of carbon dioxide emissions, new study finds
Factories mass produce goods for society and many emit greenhouse gases in the process, but not all are run by humans. Some factories lie underground and are operated around the clock by tireless six-legged workers. A new study in the Journal of Geophysical Research: Biogeosciences, a journal of the American Geophysical Union, shows leafcutter ant nests can emit carbon dioxide at a rate thousands of times higher than regular soil.

Mummified penguins tell of past and future deadly weather
New research links the mummified remains of penguin chicks in Antarctica to two massive weather-related calamities that could become more commonplace with climate change.

Bacteria found near abandoned mines could shed light on early Earth
Acidified water draining from abandoned mines, studied primarily as a modern environmental hazard, may offer insight into the oxygenation of Earth’s early atmosphere and development of life on other planets, according to a new study.

Researchers find mushrooms may hold clues to effect of carbon dioxide on lawns
Researchers at the University of New Hampshire set out to determine how rising carbon dioxide concentrations and different climates may alter vegetation like forests, croplands, and 40 million acres of American lawns. They found that the clues may lie in an unexpected source, mushrooms.

Fungi make steep slopes more stable
Fungi are fantastic. They give us beer, bread and cheese. And if those delicious reasons aren’t sufficient, then here’s another: a new study suggests some fungi can help prevent shallow landslides and surface erosion.

Small headwater streams export surprising amounts of carbon out of Pacific Northwest forests
Scientists have tracked a higher-than-expected amount of carbon flowing out of a Pacific Northwest forest from month to month through a small headwater stream, suggesting that forested watersheds may not store quite as much carbon as previously thought.

All good things…
by Nanci Bompey Nanci Bompey is AGU’s public information manager. She is spending a week aboard the R/V Oceanus with scientists from Oregon State University (OSU) who are studying the role that small rivers play in the productivity of the coastal ocean during the winter. Click here to read Nanci’s previous blogs from this trip. We arrived at the dock at Newport Wednesday evening, unloaded our gear from the ship …
Making it all work: the crew
Wednesday is the last day of the cruise – we are zig-zagging back along the coast and will head back to Newport tonight. I am finally getting the hang of walking and living on a continuously rocking boat, including being shuttled across the lab on a rolling office chair when there’s a big swell. I’ve also realized how many people, all working together, it takes to pull off a research cruise.
GeoSpace is a blog on Earth and space science, managed by AGU’s Public Information staff. The blog features posts by AGU writers and guest contributors on all sorts of relevant science topics, but with a focus on new research and geo and space sciences-related stories that are currently in the news.
