Remote sensing of supraglacial lakes in East Antarctica

Ice sheet surface hydrology is an active area of research and has recently gained prominence regarding its role in ice sheet dynamics. Understanding surface hydrological interactions and how these may influence changes in ice sheet dynamics is crucial for accurately projecting future ice sheet mass balance and sea level rise contributions.

Supraglacial lakes form annually during the summer melt season on the Greenland and Antarctic ice sheets, forming extensive networks on grounded ice and floating ice shelves that are capable of storing and transporting meltwater. Meltwater transport from the drainage of these lakes can have a critical impact on ice sheet dynamics and mass balance, including meltwater-induced ice shelf collapse.

Even though these features are widespread, they remain relatively under-researched in East Antarctica, and in particular their behaviour during melt seasons and their relationship with ice sheet dynamics is unknown.

I am therefore using remote sensing data to gain insight into the potential influence of these surface lakes on glacier and ice shelf dynamics. I am particularly interested in how they evolve over seasonal and inter-annual timescales and how this may impact glacier and ice shelf flow on the East Antarctic ice sheet.
