Study finds methane emissions from coal mines ~50% higher than previously thought

Green Car Congress

Kholod said that when a closed mine is flooded, water stops methane from leaking almost completely within about seven years. The study is the first to attempt to account for methane escaping from abandoned mines. In the United States in 2015, about one-third of abandoned mines were flooded.

Researchers find that abiotic methane can charge deepsea Arctic gas hydrates

Green Car Congress

Methane produced by serpentinization can escape through cracks and faults, and end up at the ocean floor. In other known settings the abiotic methane escapes into the ocean, where it potentially influences ocean chemistry. This is the case at Knipovich Ridge, where sediments cap the ocean crust at water depths up to 2000 meters.

The First U.S. Human-Operated Submersible Changed the Course of Oceanography

Cars That Think

Water pressure in the deep sea makes human exploration of the ocean difficult. In a 2015 interview with the WGBH Forum Network , Dudley Foster , an engineer who worked on Alvin , described the previous submersibles as “blimps.” The crew escaped unharmed, but the food they brought for lunch sank with the ship.

Argonne researchers developing multifunctional farm landscapes balancing economy, bioenergy and environment

Green Car Congress

We developed an approach to design such landscapes at a field scale to minimize concerns of land use change, water quality, and greenhouse gas emissions associated with production of food and bioenergy. If not retained by soil or taken up by plants, nitrogen escapes into air or water. Herbert Ssegane, M. 2015.04.012.
