Like a giant carbon sponge, the ocean has been absorbing much of the excess carbon dioxide humans have produced - but for how long can that last?

While we see the effects of climate change more clearly on land, the impact on our ocean is less obvious.

In this episode, guests Dr Robyn Tuerena and Dr Clare Johnson of SAMS discuss how their latest research project, C-STREAMS, is measuring changes in the ocean carbon cycle and what this might mean for our climate.

The term 'robotics' is fairly wide reaching. From amateur enthusiasts to teams of developers working on the next ingenious idea, there are many applications too.

Environmental scientists are excited about a new-found capability in environmental monitoring. Surveying an area of land or sea that would previously have taken days - even many weeks - can now be done in minutes, thanks to autonomous vehicles and their hi-tech payloads of cameras and sensors.

In this episode, Dr Niall Burnside and Libby Smith from the Scientific Robotics Academy at SAMS, talk about how these systems can be used, why training the next generation of scientists in these systems is crucial, and what the future might hold.

Marine restoration is the helping hand that nature needs in the battle against biodiversity loss and also a way to offset human impacts in the ocean.

But the benefits can be more than ecological.

In this episode, we welcome Peter Watson of SSEN Transmission, the company responsible for laying new power cables on our seabed as part of the de-carbonising of our energy grid. There's much more it wants to do, beyond rebuilding the energy infrastructure, with a little help from science.

Peter and Prof Adam Hughes of SAMS discuss what benefits marine restoration can bring, the challenges such projects face and how a children's television programme can influence the direction of an entire company...

With a global human population in excess of eight billion, governments and planners are looking to aquaculture to provide food security in a sustainable way.

But this is a diverse global industry that comes in many forms, with various societal and ecological challenges.

In this episode, two of the academics behind a highly-rated aquaculture Masters Degree, ACES, reflect on 10 years of the programme, designed to train the industry and academic leaders of the future.

Profs. Elizabeth Cottier-Cook and Laurent Barille also highlight the challenges and opportunities within global aquaculture and reflect on how they too have learned from their international programme.

Oceanographers spend a lot of time exploring the deep sea, but what is it really like taking measurements in the middle of the ocean and how is it done?

In this episode real-life Octonauts, Drs Neil Fraser and Lewis Drysdale, explain to Euan how detailed ocean observations give us an insight into the changing climate.

They also describe how the latest technology has become a game changer in the quest for more data, more quickly as we seek more accurate climate forecasts.

Images of a seahorse clutching a cotton bud, or a marine mammal choking on a plastic bag provoke shocking and saddening reactions - but how much change is made as a result?

As they discover a new plastic threat to mangrove habitats on the Ghanaian coast, SAMS scientists Prof. Bhavani Narayanaswamy and Dr Geslaine Lemos Concalves explain the extent of plastic pollution in our ocean and what we can do to mitigate some of the worst impacts.

Find out how plastic has reached every corner of the ocean environment and how it is beginning to impact on our own health.

A discovery in the dark depths of the Pacific Ocean has been challenging the scientific consensus of how oxygen is produced and has even called into question how life on Earth began.

Photosynthetic organisms like plants and algae use energy from sunlight to create the planet’s oxygen. But new evidence published by Prof. Andrew Sweetman and collaborators, including his former PhD student Dr Danielle de Jonge, has shown how oxygen is also produced in complete darkness at the seafloor 4,000 metres below the ocean surface, where no light can penetrate.

Now Prof. Sweetman is returning to the Pacific with custom-built equipment, thanks for funding from The Nippon Foundation, to find out how this phenomenon is occurring.

In this episode Prof. Sweetman and Dr de Jonge share their experience of making the Dark Oxygen discovery and the 'rollercoaster' they've experienced as their research paper continues to make global headlines.

From creating the atmosphere that led to life on Earth, to providing food for the entire ocean food web, plankton have been pivotal to the world we know today. Indeed, by absorbing vast quantities of carbon dioxide, they have been protecting us from the worst effects of global warming.
But do plankton get the credit they deserve..?

Find out from guests Prof Paul Tett and Dr Callum Whyte why plankton are the planet's hidden heroes and why we don't know enough about them. What is the ocean really like at the microscopic level, how is technology helping us see this in a different way, and what would be the cost (literally) of losing plankton from our seas..?
