Carissimi Associati SGI,
Carissimi Soci Società Associate,
su indicazione del Prof. Rodolfo Carosi (Università di Torino e Presidente SGI) vi segnaliamo l'ultimo podcast di Geology Bites (Conversations about geology with researchers making key contributions to our understanding of the Earth and the Solar System):
Di seguito troverete il messaggio dell'ideatore, Oliver Strimpel, e il link al sito web di Geology Bites.
Cordiali saluti,

Hello, listeners,
In this episode, Esther Sumner from the University of Southampton talks about turbidity currents. The common occurrence of turbidites in the geological record indicates how important such flows are. But I did not realize that a single flow can extend over a thousand kilometers and last for days. That's because these flows can travel down minute gradients (less than one degree) and be self-sustaining, with the initial flow triggering new flows as it barrels down a submarine canyon. From her wave tank experiments Sumner has replicated some of her team's underwater observations by generating a turbidity current and intruding another turbidity current into it. She also tells us about the day her team accidentally flew a remotely operated vehicle into a live turbidity current in the Mendocino canyon off the Californian coast.
I hope you enjoy listening.
Oliver
