Scientists from NOAA and the Cooperative Institute for Marine and Atmospheric Studies at the University of Miami have documented a dramatic shift from vibrant coral communities to carpets of algae in remote Pacific Ocean waters where an underwater volcano spews carbon dioxide.

Scientists probe methane mystery in Four Corners

Satellite pinpointed methane emission hotspot in remote region

Monica.Allen 0 19213 Article rating: No rating

A team of scientific investigators is now in the Four Corners region of the U.S. Southwest, aiming to uncover reasons for a mysterious methane hotspot detected from space by a European satellite. The joint project is working to solve the mystery from the air, on the ground, and with mobile laboratories.

NOAA and CIRES lead airborne field campaign to look at climate and air quality impacts

Vast regions west of the Mississippi River are under development for oil and gas extraction, and the associated equipment has become a familiar sight on any cross-country road trip or flight.  But while one focus is on what comes out of the ground, NOAA and the Cooperative Institute for Research in Environmental Sciences (CIRES) researchers and their colleagues are studying what escapes to the air—and how it is transformed in the atmosphere and affects air quality and climate.  The scientists are using a suite of state-of-the-art chemical instruments aboard a research aircraft this spring in the NOAA-led Shale Oil and Natural Gas Nexus (SONGNEX 2015) field campaign, to study the atmospheric effects of energy production in the western United States.

Tens of thousands of pounds of methane leak per hour from equipment in three major natural gas basins that span Texas, Louisiana, Arkansas and Pennsylvania, according to airborne measurements published today by a NOAA-led team of scientists. But the overall leak rate from those basins is only about one percent of gas production there—lower than leak rates measured in other gas fields, and in line with federal estimates.

New mission for the Global Hawk

NOAA is testing data collected by unmanned aircraft to improve weather forecast operations

Monica.Allen 0 25922 Article rating: No rating

For the last five years, NOAA has teamed up with NASA to fly NASA’s Global Hawk unmanned aircraft to get an inside look at how hurricanes form and intensify over the Atlantic. The NASA-led project called the Hurricane and Severe Storm Sentinel mission is demonstrating the ability of the Global Hawk to fly over hurricanes to gather continuous weather data on flights that are longer in duration than possible with manned aircraft. In the next three years, NOAA will take the next step with the Global Hawk, leading a new experiment and continuing its important collaboration with NASA. Drawing on technology and expertise honed in the current mission, NOAA will assess the feasibility of regular operations of Global Hawk to improve day-to-day forecasts of severe storms forming over the Atlantic, Pacific and Arctic oceans.
