One of my principle tasks whilst on board is to deliver Skype broadcasts to students of all ages, all over the world. The schedule was completely full several weeks before the start of the expedition and we have calculated that we will speak with over 4000 young people. This week most of the school resume their studies after the Christmas break which means 3 broadcasts a day until the end of the trip. As many of the schools are in a completely different time zone it means the majority of our tutorials are throughout the night.
