Abstract

Seismic velocity modelling shows Eriador Ridge follows the velocity structure of thickened oceanic crust and is the expected age to be the record of the PETM driving thermal plume pulse. Initial forward modelling indicates the PORO-CLIM Profile 1 dataset is sufficient to generate a magma productivity and mantle temperature record across the duration of the NAIP, though inverse modelling is needed to refine the preliminary model. Magnetic stripe modelling has reduced the range of plausible plume flux estimates, ruling out previous lowest carbon flux estimates therefore supporting a driving role for the NAIP. However some tectonic uncertainty remains, which we aim to address with the PORO-CLIM 2 cruise scheduled for September 2024.
