Jacqueline is a planetary scientist who used her PhD study to hunt for signs of the building blocks of life in dust on Mars. She established limits on these hydrocarbons that are exposed by dynamic processes on the Martian surface. Now, Jacqueline is planning to move from looking at the surface of Mars to the oceans of Earth. As a Schmidt Science Fellow, she aims to combine long-term satellite observations with ocean samples and marine wildlife observations to produce local and global maps of ocean water chemistry. By bringing together new studies with historic data sets, Jacqueline will help us to understand the impact of ocean acidification on biodiversity and inform new strategies to prevent the loss of marine species.
