We can’t wait to hear about what’s next for Phoebe. Stay tuned!
Between 11th and 12th February, 7 SENSE students participated in the ESA ESTEC workshops on the future of Earth Observation in 2040+
The workshops provided insights into EO policy, long-term strategies, and industry challenges, broadening our students’ perspective beyond academia and sparking career-related inspiration.
Interacting with experts and learning about ESA’s initiatives encouraged our students to seek future collaboration opportunities and pursue further engagement with the EO community.
For those nearing the end of their PhDs, the knowledge gained was particularly relevant to job applications and interviews, demonstrating a broader understanding of the EO landscape.
Our students valued the chance to connect with leading figures in the EO field, including ESA decision-makers and industry professionals. New connections have been formed by some that could potentially shape their future careers – fingers crossed!
Attending as a group was beneficial, offering mutual support in networking and the opportunity to collectively provide meaningful feedback to ESA on important EO strategy topics. Here are some of the thoughts shared by our students with ESA on the proposed European Blueprint for Earth Observation:
Accessibility and usability of EO data, ensuring inclusivity for researchers with varying technical expertise
ESA’s Zero Debris commitment, focusing on enforcement and international policy coordination
Resilience and redundancy in EO missions, emphasizing the need for continuity strategies
Training development, particularly in cloud computing and emerging data formats
Outreach and policy engagement, advocating for stronger EO awareness among policymakers and the public
Inspiring the next generation of EO scientists through school engagement and curriculum integration
Ethics, data governance, and misinformation, addressing privacy concerns and AI transparency
Improved communication and fostering better community interaction.
The students’ valuable comments, based on their experiences of using ESA EO data, was well received, and is being directly fed into the mission requirements for the Next Generation of Sentinel missions.
Students greatly appreciated the financial support and encouragement from SENSE, which made their participation possible and eliminated financial barriers.
A special thank you note goes to Kathy Whaler and Christine Gommenginger for their valuable input and guidance offered to the students before their trip, and to the Natural Environment Research Council and the European Space Agency.
Bryony joined NERC SENSE CDT on 1st October 2020 and completed her PhD at the British Antarctic Survey (BAS) as a University of Leeds registered student. Her research focused on the use of satellite altimetry to improve understanding of the dynamics of Antarctic grounding zones, supervised by Dr Oliver Marsh, Prof. Anna Hogg and Prof. Helen A. Fricker.

Bryony was awarded her PhD in July 2024 and—just three days after her viva—joined the RRS Sir David Attenborough on her maiden voyage to the Arctic. During the 6-week KANG-GLAC cruise to the fjords of south-east Greenland, Bryony was part of the physical oceanography team. Her responsibilities included running CTD casts to measure ocean properties in and around the fjords, and processing the continuous weather, oceanographic and seafloor data collected by the ship’s instruments. The primary goal of the cruise was to gather data to better understand the interactions between the flows of warm water into the fjords and rates of glacier melt, and the resulting impact on marine productivity, sedimentation and nutrient cycling.

A highlight of the cruise (alongside seeing polar bears and orcas for the first time!) was Bryony’s coordination of a live ‘Meet the Scientist’ workshop. This interactive session, organized in collaboration with SatSchool and Dynamic Earth, reached over 4,000 pupils across Scotland, offering them a first hand glimpse into life as a polar scientist. The event also featured a video Bryony created to showcase the team’s activities during the research cruise, which you can watch here:

In October 2024, Bryony took the next step in her career by moving to San Diego to start a Schmidt AI in Science Postdoctoral Fellowship at Scripps Institution of Oceanography. This two-year fellowship allows her to continue her pioneering research on Antarctic grounding zones, benefiiting from advanced training and application of artificial intelligence methods.

Following the success of our writing retreats in early 2024, we recently arranged for a couple more for our students with great success. Our students had the opportunity to dedicate some time to focus on writing. The retreats included mindfulness and stretching sessions, walking/running/tennis activity sessions and optional evening yoga. Our students had an excellent time and even met some friendly llamas on a chilly Yorkshire morning.
It might come as a surprise, but even in the relatively mild climate of Scotland, snow manages to endure year-round in certain mountain locations. In fact, until recently, some highland corries would house perennial snow patches for many decades without seeing them melt. The fine balance between preferential snow deposition in winter and sheltering in summer makes predicting the distribution of these snow patches a rigorous test for the kind of physically based snow models used in climate projection and impacts studies. This is the basis of my PhD research.
This summer, my fieldwork took me to Coire Cas on Cairngorm Mountain, where I aimed to map the areal extent and measure the reflective properties of some persistent snow patches. My tool for the job was a DJI M210 drone equipped with a multispectral sensor matched to the Sentinel-2 satellite sensor. Conducting multispectral drone surveys requires two things notoriously scarce in the Scottish Highlands: low winds and clear skies. Moreover, this summer was dubbed ‘Scotland’s worst since 2015,’ limiting us to a single day of drone surveys. The scarcity of cloud-free days this season is visualised in figure 1, which showcases all the satellite images captured from the Sentinel-2 over Cairngorm Mountain this summer.
Despite the inclement weather, we did manage to retrieve some spectral measurements of the late-lying snow on the 24th June (figure 2 shows one of the short-lived sunny intervals on the day). These data will help improve the snow mapping algorithms which, in turn, feed into research and contribute to discussions concerning biodiversity, water resources, and risk management in cold and mountainous regions.
In addition to my fieldwork, this summer I made my first ‘pilgrimage’ to a remote North-East facing corrie on Braeriach mountain called Garbh Choire Mòr. This location is considered to be the snowiest place in the UK and houses the famous Sphinx snow patch (see figure 3). The Sphinx has made it to popular news platforms numerous times over the past few years, and this year marks an unprecedented fourth consecutive year of its disappearance. Figure 4 shows a timeline marking the years that the Sphinx has disappeared; the trend seen here mirrors the significant impacts of climate change on Scotland’s winter conditions. Current projections suggest a stark future with ‘little to no snow by the 2080’ — a disheartening forecast for chionophiles like myself.
We are very excited to announce that our Cohort 1 student Calum Hoad secured a position as a Senior Science Officer – Seagrass Habitat Mapping. From day 1 on 11th November, Calum has faced the challenge of juggling a professional career and a PhD head-on.
A few words from Calum on his experience so far working for Project Seagrass:
“I’m delighted to be starting a new role which utilises the skills I’ve developed throughout my PhD to aid our understanding of seagrass distribution, important in the context of both the biodiversity and climate crises. I’ll be starting my new role part-time while I finish my PhD work“
We know Calum will continue to thrive and we wish him all the very best, and can’t wait to hear more about his new adventure.
Max has completed a 3-month Postdoc role at BAS and is taking up an exciting new role as a Postdoctoral Researcher in the satellite and airborne geophysics group at Kiel University.

Charlotte Walshaw, PhD researcher from the School of GeoSciences, University of Edinburgh, who led the study, said: “Our continent-scale map provides key information on vegetation presence in areas that are rarely visited by people. This will have profound implications for our understanding of where vegetation is located across the continent, and what factors influence this distribution.”
