ITGC hosts the annual Antarctica Festival, celebrating the 1 December 1959 signing of the Antarctic Treaty with a series of educational talks and activities for students of all ages. Join us for the event, which coincides with the first week of December.

Commitment was expressed in early project meetings for building a community that encompassed the IDEA goals; these found new energy through the 2020 formation of the IDEA Council (formerly known as JEDI). Annually the IDEA Council has compiled a report on the actions and progress made by the ITGC community around Inclusivity, Diversity, Equity and Access. The report serves as an opportunity to reflect on progress as well as to set goals for the coming year.

Martin is a Postdoctoral Research Associate in ice-sheet modelling in the School of Geosciences at the University of Edinburgh. His research interests focus on using numerical ice-flow modelling and geophysical data analysis to gain insight into past, current and future ice-sheet dynamics. His work is motivated by the need to quantify future ice-sheet contributions to sea-level rise.
As part of ITGC, Martin is using a combination of ice-sheet modeling, satellite data and machine learning to improve understanding of complex ice-sheet processes that are currently absent from most ice-sheet models. This includes the formation and evolution of ice damage (such as crevasses and fractures), which plays an important role in controlling the flow of ice. The outputs from this work will improve the representation of these processes in ice-sheet models and thereby reduce uncertainty in future projections.

How the mighty Thwaites Glacier in West Antarctica could contribute to global sea-level rise will form part of the final episode of the BBC Natural History Unit’s blockbuster series Frozen Planet II.
