The Prix de Quervain 2024 is awarded to Amy R. Macfarlane for her doctoral work that serves as a base to reduce major uncertainties on sea ice modelling and to improve the quality of global climate models predictions

The rapid warming in the Arctic leads to significant loss of sea ice, which in turn effects precipitation and alters the energy dynamics of the region. The research of Amy Macfarlane focused on understanding the critical role of snow and ice in the Arctic, particularly how these elements influence the region's energy budget and contribute to global climate patterns. Given the Arctic’s remoteness, the MOSAiC expedition in 2019-20 provided a unique opportunity to gather and study in-situ data over a year.

End of event

  • Amy Macfarlane and Stefanie Arndt digging a snowpit to investigate snow properties at an ice coring site. Co-located measurements were one of the advantages of the MOSAiC expedition
  • Sea ice drifts across the Arctic basin and is often under compression which forms ridges up to 5m high. Scientists needed to take care when working on the dynamic and moving sea ice. Credit
  • A windy winter day walking to work on the ice, the visibility is often reduced by wind-blown snow making it challenging for the polar bear guards
  • The snow micro-penetrometer was developed by scientists at SLF and is a tool which can quickly measure snow stratigraphy. Quick measurements are an essential consideration when working on sea ice as cold temperature, windy conditions and polar bear visits often limit the available working hours. Credit
  • A micro-computed tomography image of fresh snow dendrites. The primary focus of Macfarlanes work was to document for the first time the high-resolution snow structures on sea ice in the high Arctic
  • An illustration for the guestbook onboard showing the variety of activities conducted on the ice during the expedition alongside some unexplainable and unexpected situations
