  • The Oil Spill, Two Years Later

    Two years ago last week, on April 20, 2010, an explosion on the oil-drilling rig Deepwater Horizon caused the largest marine oil spill in history, gushing nearly 5 million barrels of crude oil over the course of three months.

  • Ocean Trash: Marine Debris From Shore to Sea

    We drove down a long dirt road on the northern side of Curaçao looking for a remote place to snorkel and sample. After a 30-minute bumpy ride, our team stepped out of the car into a breeze and the sounds of wind and crashing waves. It’s a moment I will never forget; although no one was in sight for miles, the evidence of human activity was apparent. We had stepped onto a shoreline blanketed in garbage. 

  • A Plague of Sea Stars

    Sea stars are important members of marine ecosystems, especially in the tropics. We may think of tropical coral reefs as being home mainly to fish and corals, but in fact these habitats are home to a huge diversity of ecologically important invertebrates.

    Sometimes, human influences can throw off the balance between these invertebrates, resulting in a cascade effect that negatively affects the entire coral reef ecosystem.

  • Witness to a Plastic Invasion

    It blew in for two solid days: a flotilla of plastic forks, soda bottles, rubber gloves, and other refuse. I tried to pick everything up off the beach, but when I turned around, you couldn’t tell that I had cleaned at all. When we went out in the boats, we had to go slowly in order to dodge the debris. Eventually the tide came in and swooped it all away.

  • Love Salmon? Listen Up.

    Salmon are one of the most widely loved varieties of seafood in the world. A ubiquitous alternative to meat and poultry, salmon wear a halo of healthfulness, as they are rich in protein and omega-3 fatty acids. But many wild salmon stocks are dwindling, which means that unless otherwise specified, the salmon you’re most likely to find in restaurants and stores is from a farm.

  • Peanut Butter and Jellyfish

    All over the world, people have been witnessing gigantic blooms of tens of thousands of jellyfish where once there were only a few. Fishers find them clogging their nets and costing them dearly. In Japan, giant jellyfish capable of reaching six feet across even capsized a boat that tried to bring them aboard. Where are these stinging menaces coming from and why are they everywhere?

  • Plastic Trash Plagues the Ocean

    Once upon a time, the ocean was considered the last place where we could still find an undisturbed environment. This was before the plague of man-made plastic trash flooded the seas. During my travels, I have realized that everything has changed. There is scarcely a place on Earth where plastic litter is not present. Standing on the decks of our research ship, miles away from any large urban areas, we have retrieved plastic from the deepest parts of the sea.

  • Pinning Down the Jellyfish

    Depending on whom you talk to, jellyfish are either fascinating, a nuisance, a toxic menace, or some combination of the above.

    Jellyfish plop into the media spotlight when their presence causes beach closures, or when an unlucky swimmer meets a jelly's toxic tentacle. They stimulate debate among scientists: some say that rising numbers of jellyfish are a sign of climate change and pollution, since the animals thrive in warmer, more acidic waters. Others say we don't know enough about their natural cycles to blame population booms on human activities.

  • Five Minutes for Mangroves

    Happy International Mangrove Action Day!

    This occasion is a small but vibrant tradition that has been observed annually on July 26th for nearly a decade in countries around the globe, including the U.S., India, Ecuador, Micronesia, and many others. To celebrate, some communities organize protests or restoration projects. Some convene discussions or offer educational lectures about mangrove ecology. Others simply take a moment to appreciate the importance of mangrove forests.

  • Animals and the Oil Spill: What Can You Do?

    Lately we’ve been fielding questions from Smithsonian visitors wondering how they can help with the oil spill cleanup in the Gulf of Mexico. If there is any good news coming out of this situation, it’s that thousands of people across the U.S. care deeply and are finding ways to respond to the oil spill.

  • The Invisible Loss: The Impacts of Oil You Do Not See

    Since late April, the world has watched a devastating oil spill from a BP drilling rig spread throughout the Gulf of Mexico and become one of the worst environmental disasters in the history of the United States.

  • A Current Event in the Classroom: Deepwater Horizon Oil Spill

    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 on topics like:

    • biology and ecology (How will the oil effect wildlife and the environment?),

    • physics and chemistry (How do water conditions, currents, and weather affect the way the oil disperses? What techniques and materials can we use to clean up this mess?),
