Instead of adding castaway fishing nets to already crowded landfills, Hawaii’s multi-partner marine debris group has developed a method of converting marine debris into usable electricity. The Nets-...
Mangrove is the name for a tree—and also for a complex ecosystem—that bridges land and sea. There are around 70 species of mangrove trees (meaning trees that grow in a saline salt), but they are not...
In the ocean, microscopic forms of algae, known as dinoflagellates , can "bloom" into dense patches near the surface, often referred to as "red tides." Some of these harmful algal blooms (HABs) are...
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...
Make the Connection The first step in making a difference is learning about the ocean and how your actions have an impact. Keep reading to learn everyday things you can do to help protect and restore...
Large waves are a draw for surfers, scientists and spectators alike to locations around the world. Changes to the coast and ocean floor as well as sediment flow can change the nature of a wave as it...
Smithsonian scientists and their colleagues are investigating important questions and issues related to mangrove ecosystems. • At the Smithsonian Marine Field Station on Carrie Bow Cay in Belize ,...
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...
Recorded on Feb. 15, 2011, award-winning ocean filmmaker Jean-Michel Cousteau addresses students and educators at the Third Student Summit on the Ocean and Coasts . Cousteau, president of the Ocean...
A group of students pick up trash along the coast of Guyana during the Ocean Conservancy's 2012 Coastal Cleanup, which it organizes in countries around the world every year. In 2013, nearly 650,000...
Dr. Ilka C. "Candy" Feller calls mangroves the 'nursery of the sea.' These important coastal habitats face many threats, including nutrient pollution from fertilizer runoff. That's the focus of much...
Major oil spills like the 2010 Deepwater Horizon spill are devestating, but aren’t the only way oil gets into the ocean. Nearly 85 percent of oil in U.S. coastal waters comes from runoff (roads,...
Imagine: You’re in a small submersible, and you gently settle on the soft muddy bottom at a depth of 12,000 feet. It’s absolutely dark. What will you see when the exterior lights are turned on? Will...
Around 100 million years ago, grass from land adapted to live and reproduce while submerged in seawater—the modern-day seagrasses. This sea invasion by land plants happened four separate times,...
The International Union for the Conservation of Nature ( IUCN ) maintains the Red List of Threatened Species , an inventory of the global conservation status of plants and animals. In a 2010 study ,...
Seagrasses growing on the seafloor of the Chesapeake Bay rely on light to grow—but, thanks to pollution, that sunlight has become more scarce. Nutrient runoff from fertilizers causes microscopic...
Mangroves thrive in hot, muddy, salty conditions that would kill most plants. But even these tough trees are threatened by human development. This lone mangrove shoot in South Bimini, Bahamas stands...
Oil leaks from cars and other vehicles contribute to ocean pollution.
