Science

It turns out that fish may be even smarter than we thought, with cuttlefish even demonstrating signs of communication by waving at each other!

Cooler water temperatures may help protect sunflower sea stars from a mysterious disease.

Scientists have launched an interactive global map which tracks the migratory patterns of over 100 marine species to aid in conservation efforts.

Fisheries

Sir David Attenborough has once again inspired, educated and ignited a call to action in his latest powerful film, OCEAN, now in cinemas! The film highlights the devastating impact of bottom trawling, one of the most “wasteful ways to catch fish.” Watch the trailer and join the movement by signing this petition to ban bottom trawling.

In West Africa and Sri Lanka, small-scale fishers are seeing their livelihoods threatened by a combination of dredging, industrial trawling, pollution and warming seas.

A new report has exposed the biodiversity-related lobbying efforts from some of the most influential seafood companies in the world.

Despite the introduction of some new shark conservation measures at the latest meeting of the Indian Ocean Tuna Commission (IOTC), some species remain at risk of overexploitation due to insufficient protections.

UK Overseas Territories

Satellite data have revealed that the world’s largest iceberg, currently stuck in the shallow waters off South Georgia island, is rapidly shrinking in size.

A salmon farming company is pushing to grow 50,000 tonnes of salmon in the Falkland Islands.

Marine Protection

Following the release of Sir David Attenborough’s new film, OCEAN, the Prime Minister is being urged to take bold action to protect the marine environment, as only 26 per cent of UK adults believe the government is doing enough to fulfil its international ocean protection commitments.

Trump’s executive order to lift fishing restrictions in the Pacific Islands Heritage Marine National Monument has sparked outrage, raising concerns about environmental damage and threats to endangered species. Furthermore, he is now advocating to halt federal research on space pollution!

Conservation

Although 84 per cent of the world’s coral reefs are affected by the ongoing global bleaching event, many corals continue to demonstrate remarkable resilience, like the reef in Tela Bay on Honduras’s Caribbean coast.

New eDNA traces of sharks and rays suggest they are using offshore wind farms as a habitat.

Fishing bans in kelp forests can boost resilience to marine heatwaves by maintaining predator-prey balance, which controls sea urchin populations that harm kelp. Additionally, the decline of great white sharks has set off a domino effect through the food chain in South Africa’s False Bay. Coastal ecosystems are deeply interconnected, also shown by the loss of sea stars, which has led to a surge in sea otter populations.

It has been revealed that Chile has the highest global rate of whale deaths due to ship collisions.

Climate Crisis

Since 1990, two-thirds of global warming has been driven by the world’s wealthiest 10 per cent. Additionally, human-driven climate change has intensified rainfall across the U.S. by 9 per cent in April 2025.

While global coal power plant growth slows, Indonesia continues to expand its coal use. Carbon dioxide in the atmosphere is growing faster than ever, and rising temperatures are increasing methane emissions from wetlands as microbes struggle to keep up. The loss of sea ice in polar regions due to global warming is not only increasing the amount of light entering the ocean, but also altering its colour.

Nigel Farage has criticised net-zero climate policies and is trying to turn it into a new populist campaign, pressuring Labour to defend the benefits of green action. A new poll shows most Europeans prefer domestic renewable energy over imported fossil fuels

Plastics

global study has revealed that microplastics are widespread throughout the ocean, from surface waters to the deep sea.

Scientists warn that the UK is lagging behind other nations in addressing microplastic pollution.

Aquaculture

Scottish salmon is expected to benefit from the US-UK trade deal.

Seabass farms on the moon?!

Misc

See some of Antarctica’s mysterious marine life!

Nature isn’t just a pastime, it’s a practical and spiritual need”.

“An ocean without life will absorb less carbon emissions and accelerate climate change.”

“If we save the sea, we save our world.”
