Heading Off is our weekly segment where we take you on adventures from the comfort of your home. If you've got a travel tale you'd like to share, we'd love to hear it, get in touch via 2101 or [email protected] and we might be in touch. Today we're off to the Azores, off mainland Portugal, where our guest Sarah Schmitt got the chance to experience life as a research scientist on a 10-day whale tracking expedition.
