Education: The Ocean is a Hostile Environment

Despite many images and videos of calm, flat seas, the ocean is actually a constantly changing place; the result of winds, currents, and atmospheric processes that combine to form turbulence and chaos below the waves. This presents an interesting challenge to scientists as they develop in-water instrumentation that is meant to last for years of data collecting.

Dr. Fred Bingham describes how a new type of float - called a Lagrangian float - is used for at-sea salinty research.
Global sea surface salinity

Collecting data has many challenges, whether it is in the ocean, or the vast and hostile environment of space. Dr. Eric Lindstrom addresses some of the challenges of collecting good data in difficult conditions.
