Learn about Earth’s jet streams with these visualizations from NASA. Fast-moving belts of wind, called jet streams, travel around the planet in wavy, meandering paths. In these animations, faster winds are colored red; slower winds are colored blue. These animations were created using NASA’s Modern Era Retrospective-Analysis for Research and Applications (MERRA) dataset. The first animation shows a global view of polar and subtropical jet streams. The second animation focuses on the polar jet stream over North America. The third animation focuses on the polar jet stream over Asia during a period of time in 2010.

The Traverse: Searching for Crevasses | SALSA Antarctica

The first phase of the SALSA Project involved a 100-mile traverse to subglacial Lake Mercer to deliver drilling equipment and establish a safe route. This route requires traveling through a shear zone, where movement of two glaciers causes cracks in the ice. These cracks are called crevasses and can be dangerous to the crew. The crew uses ground-penetrating radar (GPR) to navigate safely through the shear zone. This lesson explores what GPR is, how it works, how the SALSA crew uses it, and how similar radar technology could be used to explore other areas as well.
