Using geological samples from Antarctica's Dry Valleys for her doctoral dissertation, The Application of Strontium Isotopes as Natural Tracers: the Origin of the Salts in the Lakes and Soils of Southern Victoria Land, Antarctica, Jones investigated how Southern Ocean sea floor communities responded to climate changes and weatherization.[1][2][3][4] While the samples for her dissertation were provided by male colleagues who collected them in Antarctica for the Institute of Polar Studies (now Byrd Polar and Climate Research Center), Jones wanted to do her own field work in Antarctica and collect more bedrock samples and rock specimens herself in order to evaluate the salt content of a river flowing into Lake Vanda, one of the Dry Valley Lakes.[citation needed]
