How can marine preserves best protect sea creatures that move in and out of them? Two ocean scientists describe new thinking about designing marine protected areas.
DNA sequencing is making it possible for scientists to identify thousands of species of zooplankton – drifting animals that are key links in ocean food webs.
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.

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.
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.
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.
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.
