Sea surface temperatures have less influence on tropical cyclone intensification in the Atlantic than in the Pacific.

Alaska's remote location and vast wilderness contribute both to its beauty and its challenges.

For the first time, researchers have created a gram of yellowcake — a powdered form of uranium used to produce fuel for nuclear power production — using modified acrylic fibers to extract it from seawater.

Partnership to initially focus on energy system reliability, aquatic monitoring, underwater technologies, maritime security.

A new modeling approach shows that the ocean circulation determines the varying rate of global temperature response to carbon dioxide.

Improving the representation of upper-ocean layers in hurricane forecast models enhances their predictive skill.

PNNL's ThermalTracker software analyzes video with night vision, the same technology that helps soldiers see in the dark, to help offshore wind power be bird- and bat-friendly.
