Puffins once bred in great numbers on a small British islet located off the Isle of Man in the Irish Sea, but that all changed in the 1790s when a shipwreck introduced brown long-tailed rats to the island which decimated the population.

But now, following a successful rat eradication programme, conservationists are luring these social colony birds back.

In this special edition recording of Oceanographic's Roundtable, we dissect the media coverage of the stranded - and subsequent death - of the humpback whale nicknamed 'Timmy' and ask - was this €1.5 million rescue mission a question of concern, conservation, or a guilty conscience? And what does it mean for t he wider environmental problems that ocean life faces today?

The UK may officially moving away from North Sea oil and gas. In this episode, Eva Cahill explores the new Energy Independence Bill and what it means for the future of our oceans.

The Breakdown:

• The Big News: A permanent ban on new oil and gas licenses in the North Sea.

• The Trade-off: Why the massive rush to build offshore wind farms has some conservationists worried about marine habitats.

• The Security Angle: How the government plans to balance "green" energy with national security.

Is this a defining moment for marine conservation or just a new kind of industrial pressure? Tune in to find out.

In this special edition recording of Oceanographic's Roundtable, we dissect recent news that the collapse of the Atlantic Meridional Overturning Circulation (AMOC)  - the ocean mechanism responsible for moving heat around the planet - could lead to “devastating and irreversible impacts” for countries around the world.

A rare, red-listed seabird is being put at risk by Scotland’s annual guga hunt, a Freedom of Information request from animal campaign group Protect the Wild has revealed.

The controversial annual tradition of hunting young gannets for their meat dates back to the 15th century, but recently it has come under fire from environmental campaigners and conservationists in recent years for being ‘outdated.’

In this special edition recording of Oceanographic's Roundtable, we dissect a new bylaw shielding Sussex coast from bottom trawling, meaning that nearly a third of Sussex's inshore waters are now protected, safeguarding rare chalk reefs, seahorses and centuries-old marine habitats

The island has nearly quadrupled the area of its seas protected from damaging fishing practices — and those working closest to the project say it could offer a blueprint for ocean conservation far beyond Jersey's waters.

Scientists have found a marked resurgence in seabed marine life nearly a decade after protections against bottom trawling and dredging were put in place in an area off the Scottish coastline, which they say underscores the need for better protections.

Iceland is on the verge of resuming commercial fin whale hunting this summer, with a single ministerial decision now standing between declared government policy and what conservationists are calling irreversible harm.

Speakers, Vala Arnadottir, Katrin Oddsdottir, Inga Thordar, and Luke McMillan join Oceanographic's Rob Hutchins to discuss and dissect this critical news story.

Iceland is on the verge of resuming commercial fin whale hunting this summer, with a single ministerial decision now standing between declared government policy and what conservationists are calling irreversible harm.

Coral reefs face catastrophic collapse. Thermal tipping points for widespread, irreversible dieback have already been passed at 1.2–1.4°C of global warming.

In this special edition recording of Oceanographic's Roundtable, we dissect the warning that without rapid emissions cuts, restoration, biobanking, and accelerated discovery through Ocean Census, we risk losing irreplaceable coral reef biodiversity, which underpins climate resilience, medicine, and human survival.

Researchers were analysing the geochemistry of the cores, to get an insight into historic wind speeds on the island, when they found layers of ancient bird poo preserved in the peatland.

This bird poo, or guano, now gives them a window into 8,000 years of seabird history, in one of the most important seabird breeding sites on Earth: Bird Island is home to vast colonies of wandering albatrosses, petrels and penguins.

A new community screening initiative is bringing the facts about climate change and nature loss directly to the British public – and organisers want elected representatives sitting in the audience when it happens.

Scientists tracking gray whales in San Francisco Bay have found that nearly one in five individuals identified there died in its waters after becoming victims of vessel strikes, starvation, and a migration route that was never meant to pass through one of the world’s busiest ports.

On a foggy March morning, Eva Cahill spoke to the National Trust’s project manager Katy Gilchrist, and countryside manager Matt Wilson, to get a sense of the work being done in Essex's Blackwater Estuary to protect one of Britain's most storied, and most threatened, landscapes

The deep-sea covers more than half of the planet’s surface, yet less than 0.001% of it has ever been visually explored – an area approximately a tenth of the size of Belgium.

A new roadmap identifying 10,000 sites for deep-sea visual exploration, unveiled this week, is about to change that. 

Eva Cahill talks to National Geographic Explorer Katy Croff Bell about the team's ambition.

Bottom trawling undermines local food security, nutrition and livelihoods in coastal communities, according to a new global study.

The destructive fishing practice involves towing nets to catch fish and other marine species living on or close to the seabed. It accounts for over a quarter of total global marine fish catches, and a commonly sold narrative is that the practice is critical to feed a growing population.

However, this new report finds that bottom trawling reduces the availability and accessibility of fish to coastal communities and diverts good-quality, nutritious fish to global markets.

The WMO's 2025 climate report confirms the hottest eleven years on record, record ocean heat content, accelerating sea-level rise, and greenhouse gas concentrations at their highest in 800,000 years.

The lush and bountiful forests dotted along the United States’s eastern coastline are slowly being replaced by ‘ghost forests’, recognisable by clusters of greying trunks, and skeletal dead trees – and researchers have said that these forests may hold the key to understanding how coastal forest ecosystems respond to climate change.

For first time in its history, the Ocean Photographer of the Year exhibition has come to a venue in the UK. In this Friday special episode of the Ocean News Podcast, Community Editor chats with exhibition curator, Nick Ball, and the ocean photographers and 2025 finalists, Kaushik Subramaniam and Jenny Stock.

For decades, the "plastic crisis" was defined by what we could see: ghost nets, stranded whales, and islands of floating debris. But a groundbreaking global study, published this month in Nature Geoscience, has shifted the lens to the invisible.

In this special episode, we dive into a massive meta-analysis of over 2,300 seawater samples that reveals a startling reality: there is virtually no corner of our ocean untouched by human chemical fingerprints. From synthetic fragrances and UV filters to "forever chemicals" (PFAS) and pharmaceuticals, the ocean has become a global repository for our industrial output.

Climate change has been driving whales closer to shore and into the lines of California's crab fishermen. Now, a technology born from top secret Navy operations offers a fruitful solution for both

Deep-sea or critical ecosystems on land do not need to be sacrificed to limit global warming to 1.5°C, according to a new report from Institute for Sustainable Futures (UTS), in collaboration with Greenpeace International.

Coastal communities in New Ireland Province, Papua New Guinea, have been facing a growing environmental and public-health crisis since December 2025. Thousands of fish and other marine organisms have washed ashore dead, while hundreds of residents – many of them children – have fallen ill. Four months later, authorities have yet to identify the cause.

A GoFundMe campaign has been launched to support relief efforts.

Once fully implemented, the designation will bring the total fully protected area in the region to 946,571km², making it the third largest fully protected marine area in the world, behind the Ross Sea and the Papahānaumokuākea Marine National Monument.

In this episode, Eva Cahill examines a formal dossier of evidence submitted by Greenpeace International to the International Seabed Authority (ISA).

The evidence alleges that The Metals Company (TMC) has been operating in bad faith, utilising exploration data gathered under international licenses to bypass global frameworks for a unilateral U.S. mining permit.

Scientists have discovered ANCIENT CORALS and fragile deep-sea life on a previously unexplored seamount on Lord Howe Rise, confirming it as a Vulnerable Marine Ecosystem and strengthening calls for a permanent bottom trawling ban.

Listen to the concluding episode of our special mini series on Women in Marine STEM, celebrating International Women's Day on Sunday 8th March. In this episode, Eva Cahill sits down to talk with Dr Elvira De Eyto from the Marine Institute about her 20 year career in the marine science sector.

After Channel 4’s Dirty Business exposed the human toll of sewage pollution, public outrage has surged, with campaigners demanding urgent government action to reform Britain’s privatised water industry.
