I am a marine biologist fascinated by the largest environment on planet Earth: the oceans. As a student, I gained a broad knowledge on all aspects of Biology during my Bachelor’s degree at the Aristotle University in Thessaloniki, then focused in Aquatic Sciences during my Master’s at University College of London (UCL), before specialising in...
Our mysterious ocean floor
Oceans cover more than 70% of the Earth's surface, yet only 15% of the ocean floor has been mapped in detail. Much remains unknown, including the location of potentially hundreds of thousands of seamounts, which can be hazardous to navigation. Scientists at the University of Oxford are working with others to compile the most comprehensive...
Using your science to reveal how much rain fell on the dinosaurs
During the Cretaceous period (145 to 66 million years ago), the world was very different! It was hotter, with more rainfall, and dinosaurs would have roamed the lush wetlands and forests that existed in the UK. Understanding these past warm worlds can help us...
Prof Gideon Henderson, Professor of Earth Sciences, discusses exploring the ocean iron and carbon cycles aboard the RRS discovery in the south atlantic
In this video, in his Durham Club 2011 talk Professor Henderson discusses exploring the ocean iron and carbon cycles aboard the RRS Discovery in the South Atlantic.
I have always been interested in space and geology, so I am excited to be in a field where I can study rocks on other planets as part of a number of space missions - the LRO, OSIRIS-REx, Comet Interceptor, and Lunar Trailblazer missions.
What's in the Indian Ocean?
Much less is known about the Indian Ocean than either the Atlantic or Pacific. It's also less protected. What secrets lie beneath the waves? What new species wait to be discovered…? Dr Paris Stefanoudis tells us all about the Nekton project, its past and planned missions, and the role it’s playing in helping us to find out “What’s in the Indian...

Lockdown Walks - The Mysteries of Ice"On Earth when it snows, it snows crystallised water lava." Um, what? Intrigued? Join us on this chilly lockdown walk, as geologist Dr Brooke Johnson reveals some of the mysteries of ice, and tells us about the planets where snow falls as diamonds!
Why are we searching for water on the moon?
The moon may be the closest planetary body to us, but we still have a lot to learn about it. For example, what is the water-cycle like on an airless body such as the moon? How much water can be found there, and could we one day utilise this water for space exploration? In this episode of the Big Questions Podcast, we chat to Dr Katherine...
Land, Sea and Air 2 - The state of the oceans
What's in the deep ocean? And how can we study these remote and extreme ecosystems? And how is climate change affecting ocean ecosystems?
