ESI Challenge of the Month

Dr Katy Sheen (Department of Earth and Environmental Sciences) has taken up the ESI Challenge of the Month for November 2026.

 

Dr Katy Sheen will deliver the #esiChallengeOfTheMonth (hybrid) talk "Listening to the Ocean: Finding Hidden Secrets in the Noise" in the ESI Trevithick Room on Monday 30 November 1 - 2pm.

Our oceans are vast and complex, shaped by an interconnected web of physical, chemical and biological processes operating across extraordinary scales of time and space. These processes are fundamental to Earth's climate and biosphere, yet capturing their full complexity is incredibly challenging. As a result, the ocean interior remains one of the least understood environments on our planet.

In this Challenge of the Month, I'll explore how we are using sound to reveal hidden processes within the ocean interior – and how, sometimes, the information we're looking for is hiding in what we might otherwise dismiss as noise.

From uncovering beautiful patterns in deep-ocean currents, to capturing the fine-scale variability of carbon sinking into the deep sea as marine snow (a continuous 'rain' of plant and animal debris), to revealing the impacts of underwater waves generated by calving glaciers in Antarctica, I'll show how listening can open up entirely new ways of seeing the ocean.

Come and discover how sound can help us uncover the hidden rhythms, patterns and complexity of our oceans – and why listening more carefully might change the way we understand them.
