Red coral necklaces fill a store display window. The United States annually imports around one million live coral animals from tropical reefs for use in aquariums, and is the largest documented...
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,...
A stormy sea lashes the village of Shismaref, Alaska, where the coastline has eroded 30–90 m (100–300 ft) in the past 30 years.
Those of us who can't see the ocean from our window might feel disconnected from the life there. It might seem that, because the ocean feels far away, its problems will only harm those people that...
A young Kemp's ridley sea turtle ( Lepidochelys kempii ) recovers at the Audubon Aquarium of the Americas, after the 2010 Gulf of Mexico oil spill. Turtles were cleaned and nursed back to health with...
Dr. Chris Reddy, an environmental chemist from Woods Hole Oceanographic Institution studies the long-term impacts of oil spills. Watch as he digs beneath the surface in Massachusetts’ Wild Harbor...
This map is based on electronic tagging of Atlantic bluefin tuna ( Thunnus thynnus ) from 1996 to 2007. A team of international researchers officially classified the Atlantic bluefin as endangered in...
Two events made me passionate about deep-sea corals . One was my first submarine dive in a deep-sea coral bed off the Hawaiian island of Oahu. There was an incredibly lush community of corals and...
Neptune grass ( Posidonia oceanica ) is an ancient seagrass that is unique to the Mediterranean Sea. It is incredibly slow-growing; so slow that scientists estimate one large meadow that is 9.3 miles...
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...
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...
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...
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...
When hoping to discover a pearl, looking inside one of the oysters you slurp may not be the best plan. Food oysters in the family Ostreidae are able to produce pearls, however these tend to be small...
At the ends of the Earth, life thrives despite extreme conditions. In the Arctic and Southern Oceans, organisms have evolved adaptations to cope with year-round cold and six months of darkness. But...
Coral reefs are beautiful, vibrant ecosystems that house roughly one quarter of all marine species and provide billions of dollars in products and services to humans each year. But they are also...
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...
A lot can happen in five years. Since 2007, the concentration of carbon dioxide in the atmosphere has continued to go up, reaching a concentration of 400 parts per million, and with it Arctic sea ice...
