Tillie works in very extreme conditions. She is a Marine engineer on board Agulhas, the research ship that found Sir Ernest Shackleton's lost Antarctic Explorer in the Weddell Sea earlier this year. The wreck was located over 3400m down on the sea floor and temperatures were harsh and bitter at almost minus 20 degrees centigrade. Tillie speaks about her marine engineering work, love of fixing things and making them work and what it is like being so far away from home and her loved ones and how it is helped her find inner strength and hope.
