Towns and cities create an orange glow on the horizon at night. It's so widespread that it even disturbs sea creatures.

Wild dolphins are fast, smart and hard to study, but it is important to understand how human actions affect their health. So we are building a drone to sample hormones from the blowholes of dolphins.

Microscopic ocean phytoplankton feed a "biological pump" that carries carbon from the surface to deep waters. Scientists have found that this process stores much more carbon than previously thought.

Researchers are using a newly developed satellite tag to study previously unknown aspects of tiger shark reproduction. This approach could be used on other difficult-to-study shark species.

The Deepwater Horizon oil disaster catalyzed a decade of research on oil contamination in the Gulf of Mexico, from surface waters to the seabed, with surprising findings.
