Periodic Reporting for period 1 - ICEBIO (Center for Glacial Biome Doctoral Network)
Reporting period: 2022-10-01 to 2024-09-30
ICEBIO is a Doctoral Network that will train the next generation of glacier microbiology and biogeochemistry experts. The training and research programme is made up of seven interlinked Work Packages (WP). WP1 to WP4 are research work packages at the cutting edge of glacial microbiology and biogeochemistry and these will be supported by three overarching WPs (WP5-7) associated with the management, training, and dissemination of results. ICEBIO will deliver a detailed framework and database of the functional diversity and potential of the glacier biome, not only serving to dramatically advance our understanding of a threatened biome, but also laying out potential for use in economic and environmental services.
As described in annex 1, part B, Description of the Action, the overall objectives of ICEBIO are to:
(1) Prepare doctoral candidates for critical roles in the coming years of glacier meltdown, by providing urgently needed training in state-of-the-art technology, and glacier microbiology and biogeochemistry, and;
(2) Significantly advance our understanding of the glacier and ice sheet biome, its feedbacks with rapid ice disappearance, and the ecosystem services it provides.

In September 2023, a kickoff meeting was held with 8 out of 10 MSCA doctoral candidates (DCs) and 2 PhD students from EPFL. The two absent DCs accessed training materials online. Candidates began training in glacial microbiology and biogeochemistry, covering topics like glaciology, nutrient detection, and the influence of microbes on glacier surfaces. They also received field safety training, including first aid and crevasse training.
A second network-wide training event focused on Omics in the Cryosphere and Experimental Design and Data Handling, with all 12 DCs participating. Training included environmental genomics, metatranscriptomics, and metabolomic tools, integrating omics approaches with geochemical data.
All DCs have started their fieldwork, collecting and analyzing samples, aiming to publish their first research papers.
WP1 focuses on biogeochemical and microbial processes on ice surfaces. DC1 studies microbial diversity in aerosols on glaciers, DC2 analyzes microbial communities in snow, DC3 investigates metabolomics on the Greenland ice sheet, DC4 cultures bacteria from cryoconite samples, and DC5 catalogs metabolites in glacial habitats. WP1 highlights the core microbiome and metabolome of glacial surfaces.
WP2 examines subglacial biogeochemical and microbial processes and their downstream impacts. DC6 studies nutrient production under ice sheets, DC7 analyzes nutrient fluxes from glaciers to coastal waters, and DC8 investigates the export of glacial flour and its impact on fjords. WP2 shows that subglacial interactions promote nutrient transformations, affecting downstream ecosystems.
WP3 addresses ecosystem services provided by glaciers and the risks of glacier melting. DC9 studies microbial diversity in glacial flour, DC10 investigates pathogenic bacteria and antibiotic resistance genes in snow and ice, and DC12 focuses on the alga Hydrurus foetidus in glacial-fed streams. WP3 emphasizes the importance of glaciers in providing ecosystem services and the need for risk assessments.
WP4 integrates methods for sampling and analyzing glacial samples across locations. It coordinates omics and sensor technology methods and provides recommendations for future studies. WP4 ensures consistent and comparable data across ICEBIO projects.
