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.
Sustained ocean warming could greatly reduce catches of fish like these herring photographed off Norway.

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.
The British First Fleet knew little of conditions in Port Jackson, later Sydney Cove, before their arrival.

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.
The increasingly bleached coral at Black Point on the Cobourg Peninsula is a worrying sign of what’s to come for other coral reefs in Australia.

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.
Sustainable swimwear shopping means that you don’t have to worry about the sea soaking in plastic from your bathers while you soak in the sun!

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.

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.

A scientist who served on a national commission to review the 2010 BP oil spill explains why Trump administration efforts to loosen offshore drilling regulation pose major risks for minor payoffs.
A recent study shows plankton that have adapted to road salt have disrupted circadian rhythms. This finding suggests that environmental pollutants could also affect human circadian clocks.
Once unleashed, glitter gets everywhere – not just in your house, but into the environment. Time to call a halt to the glitter explosion.
