Ocean Modeller

We are looking for a post-doctoral physical scientist in the field of ocean modelling to investigate the impact of internal tsunamis generated by glacier calving events on ocean mixing, heat and carbon transport, and biogeochemistry. The postholder will develop a high-resolution ocean-sea ice model of Marguerite Bay, west Antarctica, and will liaise with observationalists and modellers, building on their conceptual models, to develop and implement a parameterisation of calving-induced mixing. The parameterisation will then be implemented in a physical/biogeochemical model with circum-Antarctic coverage to assess the large-scale impact of internal tsunamis on mixing and ventilation of water masses, biological productivity, and drawdown of heat and carbon., * Develop a high resolution (~1 km) ocean-sea ice model of Marguerite Bay using the NEMO-SI 3 framework, and verify the model by comparison with existing in situ data.

• Work collaboratively with observationalists and modellers in the POLOMINTS team across institutes to develop and implement a parameterisation of calving-induced mixing within the NEMO framework.
• Through a series of process tests, investigate the regional-scale impact of internal tsunamis on ocean mixing in relation to other drivers of mixing (winds, tides).
• Implement the new parameterisation in a large-scale NEMO-Medusa model, liaising with Earth observationalists in the POLOMINTS team to derive circum-Antarctic calving data for the parameterisation.
• Perform targeted simulations to investigate the large-scale impacts of internal tsunamis on mixing and ventilation of water masses, biological productivity, and heat and carbon transport, for the present day and for future climate change scenarios.
• Present model developments and scientific results in the peer-reviewed literature, at project meetings, and at conferences.
