Topic: Can magnets be used to tell time? Scientist Stefanie Brachfeld looks for clues about Earth’s history using paleomagnetism, which studies rocks and sediments to trace the record of the Earth’s magnetic field. Fresh from her journey in the Antarctic aboard the JOIDES research vessel, Brachfeld will show us what signs of changes in our planet’s magnetic history can tell us about the origins of the icebergs drifting through the oceans. Find out how researchers do Earth science when working on the open ocean, and how reliable compasses really are!
