NASA flights found millions of Arctic Methane Hotspots, The North Pole is one of the fastest warming places on the planet. When the temperature rises, the frozen layer of soil, called permafrost, begins to melt and release methane and other greenhouse gases into the atmosphere.

These methane emissions can accelerate warming in the future, but to understand the extent to which we need to know how much methane can be released when and what environmental factors can influence its release. NASA flights found millions of Arctic Methane Hotspots.

This is a difficult task. The North Pole stretches for thousands of kilometers, many of which are inaccessible to humans.

This inaccessibility limits most terrestrial observations to locations with existing infrastructure – only a portion of the vast and varied Arctic field.

In addition, satellite observations are not detailed enough for scientists to identify major patterns and lower environmental impacts on methane concentrations.

In a new study, scientists using NASA’s Arctic Combat Vulnerability Experiment (ABoVE) found a way to close this gap.

In 2017, they flew more than 30,000 square kilometers of the Arctic landscape with aircraft equipped with highly specialized next-generation infrared spectrometers (AVIRIS – NG) to find methane hotspots. Now the NASA flights found millions of Arctic Methane Hotspots.

This tool does not disappoint.

“We consider the hot spot as an area where there is more than 3,000 ppm of methane between the air and ground sensors,” the researcher said.

And we found these 2 million hotspots on the ground that we covered.

The document, entitled “Cross-Air Mapping”, revealed the Arctic Emergency Methane Emission Act.

The team also found a model in the dataset: On average, methane hotspots are concentrated in a radius of around 40 meters around puddles such as lakes and rivers.

After the 44-yard mark, hot spots gradually become less common and almost completely disappear nearly 300 meters from water sources.

The scientists working on this study did not have the full answer why 44 yards are the “magic number” for the entire study area, but the additional research they have done on the spot gives an idea of ​​that.

“After two years of soil testing, which began in 2018 in the Lake Alaska region with a methane hotspot, we found a sharp melting of ice that continued under the hotspot,” the researchers said.

This is the additional contribution of carbon carbon from permafrost that has been frozen for thousands of years – essentially causing germs to chew and convert to methane as long as the freezing continues to thaw.

Scientists only scratch the surface of what is possible with new data, but their first observations are very valuable.

For example, if they can identify possible causes of methane hotspots, they can more accurately calculate these greenhouse gas emissions in areas where we have no observations.

This new knowledge will enhance how the Arctic soil model represents the dynamics of methane, and thus our ability to predict the impact of the region on global climate and the impact of global climate change on the Arctic. NASA flights found millions of Arctic Methane Hotspots.
