NASA aircraft to help study oceans

An aircraft from NASA Armstrong Flight Research Center is taking part in a study of small ocean eddies, swirling areas of water that scientists believe impact how the ocean affects climate change.

The Sub-Mesoscale Ocean Dynamics Experiment, or S-MODE, uses a combination of instruments taking measurements from the air, the ocean surface and underwater to study these spiraling eddies that were first observed from space during the Apollo 7 mission.
