What is blue carbon? It's a term used to describe the carbon that is captured from the atmosphere by ocean ecosystems, mainly coastal mangroves, seagrasses and salt marshes. These coastal areas can...
Dr. Karen L. McKee collects a peat core in a mangrove forest in Belize. It will help her reconstruct how mangroves have changed over the past 8,000 years. Dr. McKee’s research has shown that when...
We’re only two months into 2010, and climate change is shaping up to be one of the year’s big buzz topics. Our friends at NOAA have released a prototype of their new Climate Portal . The site offers...
Over the past several decades, Florida’s coastal wetlands have been changing. Along the eastern shore, researchers have seen small mangrove trees appearing in areas further north than they usually...
Remotely located in the central Pacific Ocean, south of Hawaii, the Line Islands provide a remarkable research opportunity. The archipelago includes coral reefs reflecting the whole spectrum of...

Sharks are much older than dinosaurs. Their ancestry dates back more than 400 million years, and they are one of evolution’s greatest success stories. These animals are uniquely adapted to their...
Deep-sea coral beds are true biodiversity hotspots. It’s urgent that we study these extreme environments because we know so little about them, because they are important communities for so many deep-...
Oil from the Deepwater Horizon oil spill in the Gulf of Mexico impacts the coast at Pass a Loutre, La. Photo was taken on June 2, 2010. More about the Gulf oil spill can be found in our Gulf oil...
While the Ross Sea is perhaps the most pristine place left in the world’s ocean, the human footprint is fast changing this last place. Even as the effects of climate change are redefining the very...
