Earth Science reminds us that the study of Earth and its biological processes can occur anywhere—whether we realize it or not.

A diver peeks from behind a badly bleached coral in the Florida Keys National Marine Sanctuary in October 2015. Coral bleaching events caused by abnormally warm ocean temperatures continue to regularly claim the lives of coral populations around the globe.

Time-averaged image, or “timex,” created by averaging the intensity of light recorded at each spot, or “pixel,” during a video taken at Duck, North Carolina, on September 1, 2015. Blurred white zones show where waves are breaking. Light band paralleling the shore marks an offshore sandbar. Dark bands extending away from the beach indicate rip channels.

The transition between a mud flat on the interior of Bob Allen Key (Florida Bay, Everglades National Park) and the mangroves that form the islands’ protective outer berm.  These black mangroves have pneumatophores – parts of the root that function like snorkels, allowing the roots to “breathe” when water overlies the mud flat.

A mesmerizing plume creates a paradox of light and dark, brilliant and murky. The dark water of the Suwannee River flows from the Okefenokee Swamp in southern Georgia to the Gulf of Mexico in Florida. The river’s inky color comes from decaying vegetation at the river’s swampy source.

Sediment-laden water from a tributary, where development is probably taking place, entering the clearer Chattahoochee River near Atlanta, Georgia. If preventative measures are not taken on construction sites where runoff flows into a nearby stream or creek, results like this can happen.
