“We placed the camera on a cliff overlooking Ryder glacier, which we accessed by helicopter. Photos were taken every 5 seconds in order to allow detailed analysis into which processes trigger calving. At Ryder glacier, the majority of calving events were linked to waterline weaknesses – suggesting that melting of the ice by the ocean is a key driver of mass loss” says Felicity Holmes.
The project was funded by the Bolin Centre, Stockholm University, and the Polar Research Secretariat.
The time lapse imagery of Ryder glacier is part of a collection of several datasets from the Ryder 2019 expedition, that can be found at Bolin database page.


"The Bolin Centre Database welcomes other scientists at the centre to also publish datasets containing images. Contact us with your ideas," say database staff Rezwan Mohammad and Anders Moberg (bolindata@su.se).
