Methane observing firm eyes UK for key base

Science
The Canadian-based space company GHGSat says it intends to set up a global centre in the UK to analyse the emissions of greenhouse gases.The firm currently flies the spacecraft making the highest resolution measurements of methane (CH4) in the atmosphere.This satellite is the first in a planned network of orbiting observers. The British centre's job will be to take their data and assess the sources of emissions worldwide.For methane - an extremely potent greenhouse gas - these sources could be oil and gas facilities, agriculture, hydro-electric dams, coal mines and landfills.Already, GHGSat is working with operators to identify and plug leaks.It is estimated that 10 million homes could be heated with the methane escaping - largel...
Climate change: Methane pulse detected from South Sudan wetlands

Climate change: Methane pulse detected from South Sudan wetlands

World
Scientists think they can now explain at least part of the recent growth in methane (CH4) levels in the atmosphere.Researchers, led from Edinburgh University, UK, say their studies point to a big jump in emissions coming from just the wetlands of South Sudan.Satellite data indicates the region received a large surge of water from East African lakes, including Victoria.This would have boosted CH4 from the wetlands, accounting for a significant part of the rise in global methane.Perhaps even up to a third of the growth seen in the period 2010-2016, when considered with East Africa as a whole."There's not much ground-monitoring in this region that can prove or disprove our results, but the data we ...

Nasa’s Curiosity Mars rover senses methane spike

Science
The American space agency's Mars rover Curiosity has recorded its largest measurement yet of methane.The robot frequently "sniffs" the Red Planet for the gas but has never before seen so high a concentration - of 21 parts per billion (ppb).The observations are fascinating because on Earth, methane is produced in large part by living things.That's not necessarily the case on Mars; geological processes are very capable of making it as well.Nonetheless, the latest data will heighten interest in the topic.Through the course of its mission, Curiosity has noticed a number of spikes in methane, and it senses a background level that appears to have a seasonal pattern to it.But although the robot's big onboard chemistry lab - the Sample A...
Scientists find tanner crabs feeding on seafloor methane vent

Scientists find tanner crabs feeding on seafloor methane vent

Science
Feb. 20 (UPI) -- Marine biologists have discovered a group of tanner crabs feeding vigorously on a seafloor methane seep located off the coast of British Columbia. Tanner crabs are a genus of crabs sometimes referred to as queen crabs or spider crabs. All seven species of the Chionoecetes genus are often marketed as "snow crabs" in seafood markets. The discovery marks the first time a commercially harvested marine species has been observed feeding on a methane vent. Bottom-feeders like tanner crabs -- and the entirety of the ocean floor food chain -- were thought to rely exclusively on phytoplankton descending through the water column, but the latest research suggests seafloor ecosystems host diverse sources of energy and basal nutrition. "Tanner crabs likely are not the only species to g...
