Measuring ice speed in Antarctica at high resolution using synthetic aperture radar satellite data
I am a PhD student in the School of Earth and Environment at the University of Leeds, working in the Institute for Atmospheric and Climate Science (ICAS) within the Satellite Ice Dynamics (SID) group. I am funded by the School of Earth Environment, an Alumni donor, the European Space Agency (ESA) Support To Science Element (STSE) Programme, the Centre for Polar Observation and Modelling (CPOM) and I won the Funds for Women Graduates (FfWG) subsidiary of British Federation of Women Graduates (BFWG) Foundation Main Grant to support my continued studies. I was on The Alun Turing Institute Enrichment Scheme for 6 months and continue to be affiliated with the ATI.
My primary field is Earth Observation of the Polar Regions, where I use a variety of satellite data types including Synthetic Aperture Radar (SAR), optical and altimetry. I use this satellite data to look at speed, elevation change, the mass balance of ice sheets and the structure of ice shelves in primarily Antarctica. I am interested in measuring how Antarctica is changing and investigating what is driving the changes such as the ocean and atmosphere. My research focuses on measuring and interpreting changes in the Antarctica Ice Sheet using satellite data. I look at how large areas of fast-moving ice, called glaciers, flow from the ice sheet into the ocean and whether there are changes in speed. By using high-resolution satellite data we can measure these changes in speed and calculate the amount of ice loss in ever-increasing detail, enabling us to refine our projections of ice sheet’s contribution to sea-level rise.
NERC SENSE Equality, Diversity and Inclusivity Champion
I am currently seconded from my PhD as the SENSE EDI champion. The SENSE Equality, Diversity and Inclusivity (EDI) Champion aims to improve equality, diversity and inclusion practices in higher education in geosciences, one of the least racially diverse fields at the postgraduate level (e.g., Dowey et al., 2021). The SENSE Centre for Doctoral Training (CDT) won funding from the National Environment Research Council (NERC) for this role and aims to address EDI challenges faced by the environmental science PhD community. The EDI champion will analyse and assess the current EDI practices used by SENSE and design and implement new initiatives. This will include analysing applications, creating toolkits for PhD applicants and organizing wellbeing events for the current cohorts. I will be working as the SENSE Equality, Diversity and Inclusivity Champion until March 2023.
What is your background?
I’m seconding into the SENSE EDI champion role from my PhD, to work full time on a topic that I have volunteered on for many years and feel very strongly about. I am very keen to play an active role in improving the working environment for PhD students, and I hope to use this EDI role to deliver practical action and meaningful change. My PhD focuses on using satellite data to measure changes in ice flow speeds in Antarctica. I’m a first-generation PhD student and am in my final year so I can bring my lived experiences, as well as knowledge, to the role. I’m a neurodivergent, disabled woman and have navigated many of the university systems myself and hope to improve the experience for others. Alongside my PhD, and since I was an undergraduate, I have always engaged with mentoring and diversity initiatives. This has been through working for the university careers services, peer mentoring, going into local schools to work with underrepresented groups, sitting on equality, diversity, and inclusion committees and creating and running wellbeing events such as the SENSE Not Another Wellbeing workshop. I have dedicated a lot of my time to volunteering for groups such as the University of Leeds Disability, Accessibility and Mental Health Network and Polar Impact a network of racial and ethnic minorities and allies in Polar Research. Here, I lead an outreach project to engage underrepresented school children with the polar regions through augmented reality enabled postcards.
Why is this such an important issue?
Investing in Equality and Diversity has always been of vital importance, especially in geoscience, one of the least racially diverse fields at the postgraduate level . Early career researchers (in or a few years after their PhDs) are more diverse than ever . However, underrepresented groups are subject to discriminatory and exclusionary practices [1,3,4], and have been disproportionally impacted by the pandemic due to reduced opportunities . One in two PhD students experience common mood disorders such as depression and/or anxiety [5,6], a rate six times higher than the general population . Disabled students for instance must invest a lot of time and energy to access support and wait for necessary reasonable adjustments to be put in place . Our diversity is made up of a unique blend of our demographic, experiential and cognitive diversity and every person is unique. However, there are many barriers to PhDs and academia that underrepresented groups commonly encounter, but with the right support, information, and opportunity I hope academia will become a more diverse and enjoyable environment for all. Often these underrepresented groups invest a lot of time and energy in advocating for their needs, learning the ‘unwritten rules’ of the academia, having to navigate a system that isn’t welcoming to their identity and educating others to move towards a better environment, without compensation and with little to no information. I hope through this role I can contribute somewhat to easing the burden on underrepresented groups.
What will you be doing?
I will be doing a variety of activities in this role. I will be analysing applications, the application process, training programme and getting feedback from students about their experiences and potential improvements to accessibility. Spotlighting and showcasing our students’ diversity, best practices and amazing work. Creating toolkits for improving understanding and support available for students with diverse backgrounds. Running workshops and webinars on a variety of issues including careers beyond academia, the PhD application process, how to be an ally and rerunning not another wellbeing workshop. I will also be offering mentoring to our cohorts of students and identifying different support needs at different stages of their PhDs.
What are your hopes for the role?
I hope to create many useful resources and evidence that further investment in equality, diversity and inclusion should be valued highly. I hope to improve the experience of our cohorts by expanding on SENSE’s exemplary best practices and demystifying PhDs for a wider audience. I have found all my roles both voluntary and paid in this area extremely rewarding and am excited to dedicate my time and energy to this opportunity. On a personal level, I look forward to expanding my knowledge about all aspects of EDI and getting the opportunity to work with the SENSE team and students.
Any tips for those interested in engaging more with Equality, Diversity and Inclusivity?
There is so much information out there from a wide range of communities and sources. Everyone is busy, however, taking the time to educate yourself on issues that may or may not affect you will give you so much understanding and value. Start by listening to those with lived experience, this doesn’t have to be done in person and can be watching a short YouTube video or listening to a podcast and advocating for other communities. If you’re unsure of how to respond in uncomfortable situations the principles of active bystander training are a good place to start. Keeping an open mind and signing up for opportunities such as webinars and training when they come up is a great way to get started.
