Observations and measurements collected by the ocean robot can detect sudden changes in ocean conditions not captured by satellites and boost forecast accuracy with improved data.

A new study finds that the location of the Madden–Julian Oscillation affects where precipitation-rich warm conveyor belts occur over the Pacific Ocean.

Traditionally, scientists have used linear techniques to unravel the North Atlantic Oscillation’s complexities but machine learning may prove superior in capturing nonlinear relationships.

A NOAA-USGS team of scientists collected biological debris from seafloor sediments in the Gulf of Mexico. They spent months examining the microscopic shells and environmental DNA to better understand the ocean's role in removing atmospheric carbon.

A major disruption of the stratospheric polar vortex occurred. What happens next? The stratosphere will try to communicate its artistic vision down to the troposphere, but the troposphere may have its own masterpiece in mind.

With an analogy drawn from the gym, Michelle L'Heureux explains (again!) how weather (your workout) is not climate (your fitness).

The current winter season began with very warm air temperatures, resulting in slow ice formation on the Great Lakes. January 2024 has brought a sudden drop in temperatures, with the potential for more ice.

The U.S. Department of Energy (DOE) has awarded NOAA $5 million to support the conversion of the Mauna Loa atmospheric baseline observatory in Hawaii to a net-zero carbon facility. Solar panels and battery storage systems will enable the observatory to operate on renewable energy.

Larger than Vermont, an underwater seascape of cold-water coral mounds offshore the southeast United States coast has been deemed the largest deep-sea coral reef habitat discovered to date, according to a paper recently published in the scientific journal Geomatics.
