NASA Is Studying Tropical Ecosystems by Linking the Ground, Air and Space

A NASA plane came to Panama to acquire aerial images to inform scientists about the diversity of tropical ecosystems. At the same time, researchers from the Smithsonian Tropical Research Institute (STRI) in Panama collected similar data from the ground. The goal: to create an algorithm to better understand tropical ecosystems using satellite remote sensing in the future

From the surface, the havoc caused on a coral reef by a layer of low-oxygen water was barely evident.

Watch What Happens When A Coral Reef Can't Get Enough Oxygen

In September, 2017, divers observed a massive 'dead zone' rising to envelop Caribbean coral reefs in Bocas del Toro, Panama. Smithsonian post-docs formed a team to understand why reef animals were fleeing, and the role of humans in the history of hypoxia.
