Ocean Matters is getting down to business. That’s the business of investing in the ocean, its future as well as the communities that rely on it. There are lots of existing financial tools that make the world go round, so how can we use them to protect the ocean without reducing it to a number on the balance sheet? Plus, it's coming up to the end of the year so what were the big ocean successes of 2022? In this episode, Dr Helen Czerski speaks with Karen Sack, Executive Director of the Ocean...

There are several stories in this series which explore the connectivity between species, but how often do we consider the connectivity between a species, people, land and culture? Take the Pacific Salmon, for example. This is just one example of a “culturally significant fish” and are at the heart of indigenous communities in British Columbia.  By understanding the biology of salmon we can better understand the complex interrelationships between fish, people and place. But what is the...

Bizarrely, when it comes to ecology – marine systems and land systems are studied separately. But we need to better understand the “in between”. Travelling from vast rainforests, all the way to the sandy shores of remote atolls, join oceanographer Helen Czerski as she explores the power of a healthy ecosystem with Yadvinder Mahli, Professor of Ecosystem Science at Oxford University and Director of Oxford’s Leverhulme Centre for Nature Recovery. What are the processes that keep these...

The more you find out about eels, the more fascinating they become... Even on the scale of the surprises that nature can throw at us.  The European eel starts its life way out in the open ocean, far, far away from land, out in saltwater. It then migrates back thousands of miles towards estuaries, up the estuaries, into the freshwater system. It’s an extraordinary achievement but, as it travels, this is a species that encounters all the water based problems that we humans create.  Join...

In episode 12, we heard about the changes our ocean has faced in recent years and why it’s important to remain ‘ocean optimists’ in the fight against climate change. One ocean optimist is Sebastian Yancovic Pakarati, who is from an indigenous community – the Rapa Nui - on Easter Island. In 2014 the Rapa Nui lobbied the Chilean government to create a marine protected area in the waters around Easter Island. Four years later their campaign was successful and the MPA is now one of the world’s...

Everyone who studies the ocean recognizes that many parts of it are in a state of flux – always changing.  That is the natural state of things.  But sometimes changes become extreme or too frequent, and that is when problems arise. In 2015 and 2016 a massive El Nino event impacted coral reefs around the world. This week, presenter and oceanographer Helen Czerski is joined by four scientists who experienced this event and its consequences, but who still see reasons for ocean optimism.   With...

With COP26 having been and gone, one thing is clear - we need positive climate action. But while climate change has been edging its way into the public consciousness, scientists, innovators, communities and campaigners have been building an strong foundation for change.  We are not starting from square one. In this bonus episode of Ocean Matters, Helen Czerski meets one of those scientists. Dr Gareth Williams, from the University of Bangor, models climate change to better understand its...

COP26 is taking place in Glasgow, with the eyes of the world on the decisions being made, and climate change is finally getting the serious attention that scientists and campaigners have been demanding for a long time. But it’s only relatively recently that the public debate has really started to include the ocean, and a much deeper appreciation of the connection between our global ocean and Earth’s climate. This month, Helen Czerski explores a changing climate is affecting our ocean, and...

There’s no doubt that turtles are well-loved animals that have had a huge impact on cultures around the world and throughout history. But there’s a fine line between celebrating a species and taking it for yourself. Series Producer Izzie Clarke spoke with JC Niala, acting keeper of anthropology at the Horniman Museum and Gardens in London, about some of the museum’s turtle artefacts. See them for yourself here… 19th Century Comb:...

Turtles are survivors, navigators, voyagers: criss-crossing Earth’s seas while continents moved and oceans grew and shrunk.  But the modern ocean is presenting them with more challenges than ever. This month, oceanographer Helen Czerski will be swimming with Earth’s turtles, meeting the different species, spying on their lifestyles and seeing the ocean through their eyes. How do they manage their incredible feats of navigation?  And what do we need to do to make sure that these fabulous...

In episode 9, we discovered that plankton is a vital food source for manta rays so producer Izzie Clarke finds out more about these magnificent animals. What are the different species of manta ray? What’s their life history? And how do we protect them from current threats? Who better to speak to than Guy Stevens, CEO and co-founder of the Manta Trust. Visit mantatrust.org for more information on their work.  Ocean Matters is a Fresh Air Production for the Bertarelli Foundation. Follow or...

It’s often said that small is beautiful, and that’s true in the ocean too. But in the huge blue expanses of our planet, the small aren’t just beautiful – they’re essential. The 'small' here are the plankton - the tiny and varied specks of drifting life that go wherever the ocean takes them. They’re the foundation for the entire ocean ecosystem, and the starting point for almost every story the ocean has to tell. In this episode of Ocean Matters, oceanographer and physicist Helen Czerski...

"These crews are typically working 20 hours straight before they have maybe a two hour break" Fishing is having a huge impact on the lives of humans.  Slavery, abduction and even murders are taking place on fishing fleets around the world and with these crimes are being committed far from land, they are unknown or perhaps even unthinkable to most of us.  In this bonus episode, producer Izzie Clarke speaks with Ian Urbina, a journalist for the New York Times and the Director of the Outlaw...

For most of us, fish come from a shop. They’re either laid out on ice in their full glory, neatly packaged in cans or hidden away inside fish fingers. An estimated 179 million tonnes of fish was removed from the ocean in 2018, and 87% of that ended up on our plates. But those fish have a backstory that’s far harder to see, but it all comes down to the fact that we’re taking too much.     Join Oceanographer and Physicist Helen Czerski, as she explore the extent of the problem, why people turn...

“Some of the most exciting discoveries are still out there.” - Dr Mark Meekan Sharks are incredibly adapted to life in the ocean, but scientists still have so much more to learn about these enigmatic animals. The more we understand about them and their behaviour, the more we can do to protect them and prevent their numbers from falling even further. But, what does life as a shark scientist involve? In this bonus episode of Ocean Matters, Izzie Clarke spoke to Dr Mark Meekan, Principal...

Today we know of at least 1,200 species of shark, and we’re still finding more. Sharks are a critical part of life in the ocean. But the numbers don’t lie, these magnificent animals are seriously threatened. Since 1970, the global abundance of oceanic sharks and rays has declined by 71%.   In this episode of Ocean Matters, Helen Czerski explores how these masters of the ocean sense their world, why they’re not the “lone hunters” depicted by Hollywood, and why we need to protect them.    With...

In this bonus episode of Ocean Matters, producer Izzie Clarke explores the very first theories of how islands are formed from Charles Darwin and his time on HMS Beagle. Joining her is Alistair Sponsel, Historian of the Life Sciences at Cold Spring Harbor Laboratory and Senior Research Fellow in Science, Technology & Society at Harvard University, who explained where the crew’s research began and how this has shaped our understanding of remote islands. If you want to find out more about...

The tourist brochures are clear about what we should expect from a remote tropical island: bright blue water, white sand, some exotic shells and the odd coconut tree. But the reality is usually a little bit more complicated. In Ocean Matters, Helen Czerski explores these small, remote islands - distant specks of land that are dwarfed by the vast ocean around them. How do they form? What makes both the islands and their inhabitants so distinctive? And why are they disappearing? With special...

“The ocean found me, in a way…” – Dr Sylvia Earle In this bonus episode of Ocean Matters, host Helen Czerski speaks to explorer, oceanographer, and former Chief Scientist at NOAA, Dr Sylvia Earle. They discuss her fascinating career, her ongoing work to protect the ocean, and what makes her optimistic for its future.    Ocean Matters is a Fresh Air Production for the Bertarelli Foundation, subscribe now so you never miss an episode.   See omnystudio.com/listener for privacy information.

When we look up at the night sky, we can see the cosmos in all its glory; the constellations are familiar friends that we learn as children.  But even though the deep ocean is far closer, it is far more mysterious. Whilst it is hard to get to, it certainly isn’t empty or featureless. In Ocean Matters, join oceanographer and physicist Helen Czerski as she explores the deep sea: what’s in it, why it matters, and how the top of the ocean is inextricably connected to the bottom.  With special...

“I’m continued to be surprised at where microplastic are and where they come from” – Dr Imogen Napper In this bonus episode of Ocean Matters, producer Izzie Clarke speaks to Dr Imogen Napper from the University of Plymouth about microplastics and how they end up in our water sources. From small personal choices, to influencing international laws, Imogen also explains the responsibility we can all take to tackle the microplastic problem. Ocean Matters is a Fresh Air Production for the...

So often, the ocean’s problems are invisible, but plastic pollution in the ocean has rocketed up public consciousness in the past few years precisely because it, and the damage it does, is so visible. Once you start looking, it’s everywhere. Over 40% of plastic manufactured every year will only be used once. In Ocean Matters, join oceanographer and physicist Helen Czerski as she explores the impact plastic is having on ocean wildlife, the scale of single-use plastic bottles in London, and an...

“An important part of looking after the ocean is that you’ve got to look after the seabirds” If we were able to wave a magic wand and remove introduced rats from oceanic islands, is that enough to protect our seabirds? Pete Carr is an expert on birds in the Indian Ocean and, in this bonus episode of Ocean Matters, he explains to host Helen Czerski the importance to restoring native vegetation on our important seabird islands. Ocean Matters is a Fresh Air Production for the Bertarelli...

Seabirds are an incredibly versatile group of animals - they roam freely on land, soar majestically through the air and are equally at home underwater. They’re critically important if we are to maintain a healthy ocean, but half of all seabird populations are declining, and one in three is threatened with global extinction. In this episode of Ocean Matters, physicist and oceanographer Helen Czerski explores the vital link between seabirds and the sea, discovers how can seabirds help the...
