University of South Florida, College of Marine Science (USF/CMS) invites applicants for a two-year, full-time Postdoctoral Researcher to beginning April 1, 2027. The marine geology and geochemistry project is led by Prof. Jacqueline Dixon. The successful candidate will participate in a funded research cruise to the Mid-Atlantic Ridge south of the Bight Fracture Zone (~57°N) to investigate off-axis volcanoes and to perform major, trace, and volatile element geochemical analyses on oceanic basalt samples. Project Overview: Large buoyant mantle upwellings associated with prominent gravity anomalies (MBAs - mantle Bouguer anomalies) are thought to occur within a deep, low-viscosity, damp melting interval, where volatile- and incompatible element-rich melts form and are efficiently transported to the surface through reactive flow channels. Our cruise, tentatively scheduled for June 2027, will map and sample a subset of off-axis volcanoes and axial rift sites south of the Bight...
