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.
