Overfishing and sedimentation have heavily impacted this reef off the western coast of Guam. More about coral reef ecosystems can be found in our Coral Reefs featured story .
by Amanda Feuerstein On the east coast of Mexico’s Baja California Peninsula lies a small marine protected area that represents one of the most impressive successes in ocean conservation. Cabo Pulmo...
More than ever, the fate of the ocean is in our hands. To be good stewards and leave a thriving ocean for future generations, we need to make changes big and small wherever we are. To make a positive...
Ocean acidification is sometimes called “climate change’s equally evil twin,” and for good reason: it's a significant and harmful consequence of excess carbon dioxide in the atmosphere that we don't...

White abalones are slow-moving, algae-eating mollusks. Rapid overharvesting since the 1970s has resulted in white abalones becoming the first marine invertebrate listed as endangered on the...
Imagine you’re an alien seeing Planet Earth for the first time. What do you see from your spacecraft? A blue planet with over 70% of its surface covered by ocean. From space it’s obvious how...
We began this journey three months ago, a team of scientists and filmmakers traveling the East African coastline by boat to document and research the status of coral reefs from South Africa to Kenya...
A dredge from the U.S. Army Corps of Engineers can be seen removing a sandbar off of Virginia Beach, VA. This type of removal occurs in order to clean up the seafloor or to allow for large ships to...

In coastal towns and cities, vast areas now inhabited by super markets, houses, roads, parking lots, hotels and schools were once occupied by mangrove forests . Growing out of the ocean and onto the...
A lot can happen in five years. Since 2007, the concentration of carbon dioxide in the atmosphere has continued to go up, reaching a concentration of 400 parts per million, and with it Arctic sea ice...
How do we know what coral reefs looked like hundreds of years ago? Often times, we are simply left wondering. Scientists can get an idea from naturalist recordings, but there are many unknowns and...
