We are delighted to be joined by Dr Meg Baker who will be discussing What lies beneath: measuring underwater sediment avalanches in the deep ocean. 

Meg says – Seafloor avalanches of sediment, called turbidity currents, transport huge volumes of sediment and organic carbon to the deep‐sea, and can break crucial seabed telecommunication cables that underpin global data transfer. However, the inaccessible, fast and destructive nature of these events make them very difficult to measure and therefore they are poorly understood. This talk will present recent oceanographic expeditions that have utilised new technology to measure turbidity currents ‘in action’ to reveal new insights into their frequency and dynamics.

About our speaker – Dr Meg Baker is a Research Fellow in Marine Geology in the Department of Geography at Durham University. Prior to joining Durham University, she completed her PhD in Oceanography at Bangor University. Her research focuses on studying the transport of sediment and organic carbon to the deep ocean by underwater avalanches of sediment called turbidity currents. To answer research questions about turbidity currents, Meg uses oceanographic field measurements, sedimentary deposits, and small-scale laboratory simulations.
