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 special thanks Sarah Fowler from Save Our Seas Foundation, Dr David Jacoby from the Zoological Society of London, and Dr Al Dove from Georgia Aquarium.

Our ocean is the earth's defining feature.

But the blue of our blue planet is so much more than just a colour. It is rich with life and plays an important role in keeping our planet stable and healthy. Worryingly, we are seeing our ocean change, for the worse.

In Ocean Matters, join oceanographer and physicist Helen Czerski as she meets the scientists who are working to save our ocean and marine life in one of the most remote parts of our planet.  Together, we’ll explore how the cutting-edge marine science research that’s going on there – and other places we visit - is helping to protect species across the world, and better understand what needs to be done to save our seas.

Ocean Matters

Sharks – Masters of the Ocean

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 Risk and Resilience Action Alliance (ORRAA). ORRAA is a global multi-stakeholder alliance working around the world to drive investments into coastal and ocean resilience and nature.

Ocean Matters is a Fresh Air production for the Bertarelli Foundation. The producer is Izzie Clarke.

Finance – Protecting 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 current state of wild salmon? 

Join oceanographer and host Dr Helen Czerski with scientist and citizen and member of the Nisga’a First Nation Dr Andrea Reid, as they explore the importance of the Pacific Salmon to indigenous communities. Andrea is the Principal Investigator at the Centre for Indigenous Fisheries in the Institute for the Oceans and Fisheries at the University of British Columbia.

Learning from Indigenous Fisheries

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 important ecosystems in check? And can a healthy island ecosystem improve the state of our ocean?
