Leading from the front: women shaping Antarctic science on the COOKIES voyage By Joline Lalime, Sea2SchoolAU and Dr Linda Armbrecht, ACEAS/IMAS (University of Tasmania) Antarctica, the Southern Ocean and marine expeditions were once territories where women were excluded by tradition, superstition (bad luck), and systemic barriers. Today, that history is being actively rewritten through leadership,
