Following Microscopic Life Through the Glacier Melt Season – New POLARIN Ambassador Blog Post!
Following Microscopic Life Through the Glacier Melt Season In summer 2025, the GLASS (Glacier Algal Sampling Strategies) project from the University of Bristol headed to Tarfala Research Station in northern Sweden to study blooms of microscopic algae on Storglaciären through the melt season. A heatwave in July brought melting around the station and uncovered colourful algal patches in the snow, giving the team an early glimpse of life on the ice. By August, the bare glacier surface allowed detailed sampling and drone surveys that captured the peak of the bloom, and a final visit in September captured how these ecosystems had evolved by the end of the melt season. These field campaigns are helping scientists build the datasets needed to improve how satellites observe biological activity on glaciers in a warming world.

GLASS was funded by POLARIN’s first call for Transnational Access to Research Infrastructures.
