At Kīlauea in Hawai'i, a recent volcanic eruption has created some of the most spectacular sights in nature. But also danger for those around it.
Scientists have mapped a huge dead zone in the Gulf of Oman, without enough oxygen in the water to support life. This Speed Read explains why dead zones form in waters around the world.
Biologists are finding new evidence that these ocean invertebrate grazers don’t just ingest whatever they catch. They can actually be picky eaters – and their choices might influence ocean food webs.
During sea turtle nesting season, scientists collect data and assess how turtles are doing. But they know less about how plastic pollution, fishing and warming oceans are affecting turtle numbers.
Fish are a key food source for millions of people worldwide. But a recent study finds long-term warming over the next 200 years could starve tiny plankton, with impacts that would ripple up food chains.
Banning plastic bags in food distribution is complicated and not all municipalities are on board. Are bioplastics a solution?
The noise from motor boats, sonar and other industrial activity interferes with the underwater chatter of fishes.
With coral reefs in crisis around the world, many organizations are working to restore them by growing and transplanting healthy corals. A new study spotlights techniques that help restored reefs thrive.
When the First Fleet sailed into Sydney Cove in 1788, they entered an ancient and unforgiving landscape. A new book charts Australians’ relationship with one of the world’s most volatile climates.
Coral bleaching has struck the Northern Territory, adding urgency to the need for better national management strategies for our warming oceans.
Diving without oxygen tanks requires you to enact some very weird and very strange and not all that well understood physiological feats just to stay alive.
Sea snakes spend their lives in the water, giving birth to live young at sea, so why are they only found in some of the world’s oceans? The answer lies in a combination of climate and geography.
Summer may have come to an official end, but the plastics from your bathers might still be at the beach!
Many critics say that fish farms mainly sell their output to wealthy countries and don’t provide much benefit to poor people in producing countries. Three aquaculture experts show why this view is wrong.
Nightvision, ejectable stomachs and regrowable arms mean starfish are more than meets the eye.
Millions of tonnes of plastic garbage winds up in our oceans each year. Voluntary pledges haven’t worked. It’s time for Canada to advocate for an international plastics treaty.
Research suggests a new threat to life on Earth from the meteorite’s crash: Via seismic waves, the impact triggered massive undersea eruptions, as big as any ever seen in our planet’s history.
The Mariana snailfish lives nearly 27,000 feet underwater, but has features that help it adapt to intense water pressure and cold. Physiological limits may prevent fish from surviving in deeper water.
Scientific fieldwork that happens underground and underwater in spectacular but dangerous caves opens a window on a largely unknown world.
