Research Fellow in Geophysics Geology & Geophysics

Iceland is underlain by a plume in the mantle, with past fluctuations in melt production recorded as a series of V-shaped ridges and troughs in the north Atlantic. This project will test the hypothesis that the fluctuations in melt production are primarily caused by changes in the temperature of the mantle plume. We will collect seismic profiles on board the R/V Marcus G Langseth in late summer 2024, along both the Reykjanes Ridge south of Iceland, and a flowline that crosses the ridge. This will include 150 OBS stations and a multichannel seismic reflection profile using a streamer up to 15km in length, to measure variations in the crustal thickness and the crustal velocity structure. The flowline also crosses several existing IODP Sites where the composition of the upper igneous crust has been sampled. This unique combination of datasets will allow us to test whether the V-shaped ridges really do represent changes in mantle temperature within the plume.
There may be the opportunity to sail on the R/V Marcus G Langseth as we collect the data. You will then work to process and interpret the seismic datasets to investigate the structure and properties of the crust and the upper mantle. In addition to producing seismic reflection cross sections and velocity models from travel time inversion of the OBS data, we plan to carry out full waveform inversion of the datasets. The post has an expected duration of 34 months., Applications will be considered from candidates who are working towards or nearing completion of a relevant PhD qualification. The title of Research Fellow will be applied upon completion of PhD. Prior to the qualification being awarded the title of Senior Research Assistant will be given.
