Floodwater carries dense clouds of sediment, choking the lush seagrass meadows on which these gentle grazers rely.

Sharks are much more severely threatened by humans than vice versa. A marine biologist explains how people can help protect sharks and why some strategies are more effective than others.
The photographs show how climate change is disrupting our marine ecosystems – sometimes in ways previously unknown to marine scientists.

Spider crabs form huge underwater piles, some as tall as a person. These fascinating crustaceans are on a risky mission – to get bigger.
The sound of the marine environment has been underestimated, mainly because it is not audible to the human ear.
The ocean is often considered a silent universe. But many recent studies highlight the importance of the soundscape for many marine species, both large and small.
Rotting seaweed has plagued the Caribbean, Gulf of Mexico, US and West African coasts for a decade. So we’ve developed a new approach to turn what’s now rubbish into green electricity and fertiliser.

Australia’s ‘blue economy’ needs a strong basis in marine science.
The remarkably resilient structure is in good health, for now. But work is needed to ensure it is preserved for future generations.
Recent flooding may have reduced the remaining coral population by 90%. Combined with damage from fishing, boating and coastal development, the species may be gone in a decade.

Submerged in the waters off Western Australia lies an ancient site home to Aboriginal people thousands of years ago, when sea levels were lower than they are today.
Researchers use Atlantic mackerel for bait on long-lining fishing sampling expeditions in the Gulf of Mexico..
The Deepwater Horizon oil disaster catalyzed a decade of research on oil contamination in the Gulf of Mexico, from surface waters to the seabed, with surprising findings.

Empatheatre’s latest production is more than a play about three characters who live near the sea. It’s a model for collective consultation on how to save the ocean.
Whale watching (here, off Húsavík, Iceland) may be better for the local economy than whale hunting.
Icelandic whalers have killed more than 1,700 whales since a global ban was adopted in 1986 – up to 2019, when no hunts took place. Is Iceland quietly getting out of the business?

Few feel the pain of the Great Barrier Reef’s decline more acutely than the scientists trying to save it. Ahead of a UN climate summit, two researchers write of their grief, and hope.
Delegates at this week’s marine science conference in Fremantle take a plastic-free coffee break.
This year’s national conference of the Australian Marine Science Association is a plastic-free zone, as marine scientists aim to reduce the environmental burden of throwaway plastic.
New Zealand’s coastline spans a distance greater than from the south pole to the north pole.
New Zealand has one of the world’s largest ocean territories, but the marine environment is at risk from climate change, pollution and fishing.
A few days after baby molluscs come out from tiny eggs, they start building their shell layer after layer.

Molluscs that have shells - like pipis, clams and oysters - have to build their own shell from scratch. And they keep building it their whole life, using chemicals from the sea and their own bodies.
Eastern rock lobster on sale at Sydney’s fish market. Our preference for a limited variety of seafood drives up prices and threatens the industry’s sustainability.
Australian fishing boats throw away up to half the fish they catch. To make the seafood industry sustainable, we need to eat all the fish that get caught.
The scientific drilling ship JOIDES Resolution arrives in Honolulu after successful sea trials and testing of scientific and drilling equipment.
The ocean floor holds unique information about Earth’s history. Scientific ocean drilling, which started 50 years ago, has yielded insights into climate change, geohazards and the key conditions for life.
