The glaciologist works in some of the harshest conditions on earth but she's most concerned about how much the environment is changing.
It holds a very dear place in Dr Sevestre's heart.
"[The archipelago is] covered 60 per cent by glaciers, so it's truly paradise for a glaciologist like me. But it's also a place where you feel the true power of nature," she says.Indeed, the team faced such bad weather on their 2021 expedition that they had to bury themselves in snow to protect themselves"We got to experience some of the most terrifying conditions I've ever seen on the archipelago.
But while this work has its perils, it's a risk Dr Sevestre is willing to take to raise awareness of the impact climate change is having on glaciers and the implications this has on rising sea levels. "What's super important about the surging glaciers is that they are game changers when it comes to predicting future sea level rise. This is a big part of our work right now," she says., which tracks the speed of surging glaciers."When you look at glaciers around the world, you might think that they are pretty static, that these glaciers don't do much apart from melting," she says.
However, the results for Svalbard have shown that these types of glaciers can change their behaviour."For most of their lives they are lazy, they don't do very much, they move extremely slowly," she says.According to Dr Sevestre, the organisation has recorded glaciers moving over as much as 10 to 50 meters per day, over several years.
