Liz Sikes is a professor of oceanography at Rutgers University and a paleoceanographer. The unifying theme of her work is carbon cycling. She is investigating circulation in the Southern Ocean to determine how this traps and releases CO₂ from the deep ocean on glacial time scales. Liz also investigates past sea surface temperature changes in the oceans around New Zealand and Australia, as well as the sources, pathways, and sinks of terrestrial and marine carbon in the modern environment to understand their impact on coastal ocean acidification. Liz was the awarded recipient of the American Geophysical Union’s Cesare Emiliani Lecture for 2020 in recognition of her outstanding contributions to her field.
