Tom Peschak, a photojournalist with the Save Our Seas Foundation, describes the devastating effects shark nets have on ocean life along the South African coastline. The nets were installed to protect...
The threat that climate change poses to polar bears has received a lot of attention, but they are not the only Arctic species at risk. Ice-loving seals, such as harp, hooded and ringed seals, are...
Since 1987, researchers have been tracking Phoenix, one of the last North Atlantic right whales living today. It's estimated that there are fewer than 500 of these whales alive today. Read her story...
A placard warns residents that water—and anything else—that goes own this storm drain makes its way into the Potomac River and, eventually the ocean.
An early scale model of North Atlantic right whale Phoenix indicates the location of scars on her tail from entanglements with fishing gear. More about the right whale can be found in our Tale of a...
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...
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...
Penguins are odd birds. For one, they cannot fly (but they are amazing swimmers), and, contrary to popular belief, the majority of penguin populations live in warmer regions. Only four of the 18...
This coral reef in the Western Pacific Ocean was killed by human input of silt and sand from nearby islands reaching the coral reef habitat. More about coral reef ecosystems can be found in our Coral...
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-...
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...
In 1872, the United States did something remarkable. We set aside one of our greatest natural treasures, Yellowstone National Park , for future generations to enjoy and appreciate. The logic was...
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,...
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-...
This shrimp farm in southern Belize is just one example of how mangroves worldwide are giving way to human development. In just the last decade, at least 35 percent of the world's mangroves have been...
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...
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...
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...
