Dixon studies the role of water and carbon dioxide in the generation and evolution of basaltic magmas with an emphasis on submarine volcanoes. Her work includes solubility studies of water and carbon dioxide in basaltic melts, vapor saturation and degassing models, and modeling of volatile contents in primary magmas and the mantle. Her research has focused on the mid-ocean ridge system, Hawaii, the Galapagos and the Easter Salas y Gomez Seamount Chain.

Conway’s research group aims to understand the geochemistry of trace metals in the marine and earth system and the role they play as micronutrients and/or toxins in marine biogeochemical cycles, with effects on the global carbon cycle. The group employs techniques including measurement of trace metal isotope ratios and concentrations in a range of materials including aerosol dust, rocks, sediments rain, seawater, ice-cores, marine particles and biological materials. The group aims to shed light on the biogeochemical cycling of trace metals in the modern ocean and is interested in developing and applying isotopic tracers as proxies for oceanic processes in the geological past.
