For example, dedicated methane analytics and reporting is possible for asset managers and stakeholders responsible for environmental, social and governance (ESG) factors for understanding investment risk and growth opportunity. Likewise, satellite observations could play a key role, but the current sources of satellite data are also limited. The TES sensor on NASA’s Aura satellite can measure methane, but it lacks sensitivity in the lower troposphere, where methane emissions occur. Methane leaks silently from natural gas and oil wells and pipelines, as well as coal mines. COVID-19 Response. The Atmospheric Infrared Sounder (AIRS) aboard NASA’s Aqua satellite has been in operation since 2002. Microbes on the ocean floor and living within the water column usually consume it or convert it into carbon dioxide first. The methane seeps that Anthony has found are not necessarily caused by global warming, and there is no way to know how the number today compares to the number that existed during earlier periods. Human Presence If your company has a current subscription with S&P Global Market Intelligence, you can register as a new user for access to the platform(s) covered by your license at Market Intelligence platform or S&P Capital IQ. Meanwhile, Haris Riris, a scientist based at NASA's Goddard Space Flight Center, is developing a next-generation lidar sensor that could have even greater sensitivity and precision than the sensor on MERLIN. Data from the new projects should become available by 2023, making it wise for oil and gas companies to start addressing methane emissions now, according to Erin Blanton, a senior research scholar focused on natural gas at the Columbia University center and one of the authors of … This would not produce a large signal as the methane will be more distributed.”. You can be assured our editors closely monitor every feedback sent and will take appropriate actions. In nighttime satellite imagery, the light from Eagle Ford competes with nearby cities of San Antonio and Austin. Fuel extraction is not the only reason for the rise, but scientists are working hard to figure out where and how much natural gas is leaking. Schneising and colleagues found a significant increase in the concentration of methane over both gas fields as drilling activities ramped up. Airborne measurements of atmospheric methane column abundance using a pulsed integrated-path absorption lidar. When methane has more neutrons in its chemical structure, it is said to be a “heavier” isotope; fewer neutrons make for “lighter” methane. (NASA Earth Observatory image by Joshua Stevens, using data from the EIA.). Just a small portion of gas hydrates (about 3.5 percent) occurs at depths where warming ocean waters may be causing the methane hydrate to break down, sending methane bubbling up. But the difficulty of accurately detecting the oil and gas sector's methane emissions has been a critical challenge for the industry and regulators. Indeed most gas hydrate—about 99 percent—is sequestered in deep-water environments where temperatures are cold enough and the pressures are great enough for the deposits to remain stable. There is another vast store of methane on the planet. The cause of the recent increase remains a topic of study and debate, explained Ed Dlugokencky, a NOAA scientist who leads a team monitoring methane trends. Although the CARVE campaign ended in 2015, Miller will continue the measurements through NASA’s Arctic-Boreal Vulnerability Experiment (ABOVE), which began in 2015. Different processes produce different proportions of heavy and light methane. In the meantime, Kort cautions that natural factors, such as the topography and wind patterns, also play an important role in causing hot spots to show up in the SCIAMACHY data. ", latest-news-headlines ), “It is obvious from the global data that understanding what is happening in wetlands, especially tropical wetlands, is critical to understanding global trends,” said Frankenberg, who is now based at the Jet Propulsion Laboratory.
