In a first interview Oscar Schofield from Rutgers University in the US explains how underwater gliders can spend months at a time at sea and describes the first AUV mission to successfully cross the Atlantic (for a Hollywood account of the mission have a look at the above video). Our second guest Mark Moline is Professor at the Biological Sciences Department and member of the Center for Coastal Marine Sciences at Cal Poly State in California. Moline reports on a month-long mission using AUVs for underwater exploration in the Arctic Winter resulting in some surprising findings. Read on or tune in!
