About the Project

Background
Sea level rise will threaten the livelihoods of over one billion people living close to coastlines and is one of the defining challenges of the 21st century. However, predicting future sea level is highly uncertain; debate about the future contribution of meltwater from Antarctica, which could contribute more than 1m of sea level rise by 2100i, is particularly intense. The most rapid melting occurs in West Antarctica, where relatively warm water from the open ocean reaches the shallow seas in front of the retreating glaciersii. This supply of warm water is highly variableiii, and may change in response to an increase in Antarctic meltingiv. More research is needed to predict future changes.

Methodology
You will use existing simulations from state-of-the-art climate models to investigate how the ocean will influence Antarctic ice melt during the 21st century. It is crucial to assess how well models simulate key ocean processes. To do this, you will explore how the glacier-ward flows of warm water vary between different models that have different spatial resolution and different representation of ocean-ice interactions. You will use the latest international observations from around Antarctica to perform process-based model evaluation, comparing the models and reality. Your work will improve our understanding of how glaciers in Antarctica will contribute to future sea level rise, with the potential for your findings to feed into future international assessments of climate-induced sea level rise.

Training
You will join an active research group in meteorology, oceanography and climate at UEA. You will be trained in modelling the climate system and you will learn to use state-of-the-art computer systems to rigorously analyse large model and observational datasets. You may also have the opportunity to participate in oceanographic fieldwork around Antarctica.
