Waves lap against the shore on the south coast of England and the North coast of France – but the answer to this puzzle is in the wind and the land, not the waves themselves.
Strange frond-like sea creatures are among the planet’s earliest animals, but new research dates them and the entire animal kingdom to much earlier than first thought.
Plastic bags are commonly mistaken for food by sea animals. They require a lot of energy and resources to be made, and have caused floods in some countries.
The world has some 500 million square kilometres of ocean. But just 55 million square kilometres remain untouched by intensive human activities such as fishing.
If we are truly invested in addressing the issue of marine plastic and offsetting the potential harms, we have to understand which fish eat plastic and which ones don’t.
The Big Bang created a cloud of dust and rocks that included a lot of rocks that were made of ice, like giant snowballs. That’s where some of the water came from.
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.
