Part 6 of a 6-part series describing WHOI's efforts to understand the scope and impact of the Deepwater Horizon oil spill in the Gulf of Mexico. "Assessing the Impacts" describes a range of work by...
Any floating object in the ocean tends to attract life; fishermen know this and deploy floating buoys to concentrate fish for harvesting. Plastic marine debris is no different and, at microscopic...
Sometimes, a tragic event can become a powerful teaching opportunity. The Deepwater Horizon oil spill in the Gulf of Mexico has the potential to capture students’ attention and stimulate discussion...
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...
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...
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...
In the Pacific Ocean, four ocean currents merge to form the North Pacific gyre, also known as the North Pacific Subtropical High, which spans the western US to Japan, and Hawaii to California. This...
While bottom trawling—a fishing method that drags a large net with heavy weights across the seafloor—fishermen often catch more than their target fish. Here, they've scooped up a large deep-sea coral...
Today, carbon dioxide (CO2) levels in our atmosphere are the highest they've been in 15 million years. It's the cumulative impact of an ever-expanding population -- 7 billion people and rising -- and...
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...
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...
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...
Sharks have a long and impressive lineage. Ancient sharks were cruising the ocean 400 million year ago- long before dinosaurs roamed on land. Relatives of the great white like the giant megatooth...
When people sail the sea, marine organisms tag along. If carried long distances, these hitchhikers can invade and disrupt ecosystems far from their natural homes, pushing out the local species. Some...
Can painted wooden fish on a schoolyard fence change human behavior and help clean up the ocean for the real salmon? Stream of Dreams in British Columbia thinks so, and a lot of wooden fish and some...
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,...
Dr. Demian Chapman of the Institute for Ocean Conservation Science at New York’s Stony Brook University explains how DNA extraction from shark fins can identify the species of shark and where the...
