5th June 2024 Environment Day
With this beautiful image taken by our researchers on the Austre Broggerbreen glacier in Svalbard Islands we want to remind the importance of the cryosphere in the Earth ecosystem, as an archive of climate history, a reservoir of fresh water and a sentinel of the climate change.
POLAS expedition in Arctic
Our researchers have just returned from an Arctic expedition to the CNR-ISP Italian base "Dirigibile Italia" in Ny-Alesund, Svalbard Islands. During this month, researchers from the Department of Earth and Environmental Sciences of the University of Milano-Bicocca and the Department of Physics of the University of Milano collaborated on the POLAS research project to carry out studies on the mineral dust contained in the snowpack, about the crystallography of snow and how sunlight penetrates the snowpack. Several glaciers on the island of Spitsbergen were sampled although the high temperatures and rain, abnormal for the season, made operations difficult. The collected samples will reach the EuroCold Lab. in the coming months and will be analyzed with the most advanced particulate measurement techniques. The data collected by the snow probes are already fed to the computers to create the necessary models and interpretations.

Camera on the Rutor glacier
Great news from the Rutor glacier in Aosta Valley!
Claudio Artoni and Marco Potenza reached Colle del Rutor where 2 years ago they installed a camera for the OPTICE project.
The camera was in excellent conditions, it seemed that wind, snow, rain and sun hadn’t affected the solar panel and the chassis.
In fact, after having removed it and having verified its functioning, the researchers founded that it had worked continuously from the day of installation to today, taking two photos a day.
Now an ongoing elaboration work is up to the members of the OPTICE project to create a time lapse on the state of the glacier and to see the trend of snowfalls over the last two years.
To know more about the project visit the OPTICE website.

“ClimADA”, the climate of the last centuries in the Adamello Glacier
ClimADA starts, the second phase of the project which in April 2021 allowed the extraction of 224 meters of ice from the Adamello Glacier, thanks to an operation never before successful in the entire Alpine arc. In fact, the series of analyzes aimed at reconstructing the climatic and environmental conditions of the central part of the Alps has begun in the Bicocca EuroCOLD laboratories, which will allow us to go back about 1000 years.
Ice core drilling progression on
Adamello Glacier
The drilling end at -225 m depth, after find some sones in the ice core. It is too dangerous for the drilling system to continue. Great shot for the laboratory collaboration and for the ADA270 project.
Drilling Start at Mandrone Glacier
The 8th of April 2021, on the Pian di Neve, the accumulation area of the Adamello Glacier (Adamello Group, Brescia, Italy) start the drilling activities to reach the bedrock at 270 m below the surface.
Headed by Regione Lombardia and including many other regional entities and private sponsors, the University of Milano-Bicocca chair the scientific activity in collaboration with Paul Scherer Institute and The Coherentia spin-up to realize the drilling activities, collect the ice cores and monitoring the evolution of the glacier.
The bottom of the glacier can preserve ice that can 1 thousand year old, permitting to reconstruct the variability of he regional climate and history of environment of the last millennium.
Covid-19 emission impact
The Copernicus Atmosphere Monitoring Service (CAMS) provides daily analyses of hourly concentrations of regulatory air pollutants.

In figure the emissions in January and March 2020 along the Po Plain in Northern Italy.
Commentary on Science
The recent EuroCold Lab collaboration paper, publish on Nature Communication, create strong interest on the scienific community as demontrate the news on Science journal.
Researchers have discovered a common martian mineral deep within an ice core from Antarctica. The find suggests the mineral—a brittle, yellowbrown substance known as jarosite—was forged the same way on both Earth and Mars: from dust trapped within ancient ice deposits. It also reveals how important these glaciers were on the Red Planet: Not only did they carve valleys, the researchers say, but they also helped create the very stuff Mars is made of.

From Antarctica to Mars
On Nature Communication the first result comparing Antartic formations of mineral in deep Antarctic glacier and the possible glacier effects on Mars.
Many interpretations have been proposed to explain the presence of jarosite within Martian surficial sediments, including the possibility that it precipitated within paleo-ice deposits owing to englacial weathering of dust. However, until now a similar geochemical process was not observed on Earth nor in other planetary settings. We report a multi-analytical indication of jarosite formation within deep ice. Below 1000 m depth, jarosite crystals adhering on residual silica-rich particles have been identified in the Talos Dome ice core (East Antarctica) and interpreted as products of weathering involving aeolian dust and acidic atmospheric aerosols. The progressive increase of ice metamorphism and re-crystallization with depth, favours the relocation and concentration of dust and the formation of acidic brines in isolated environments, allowing chemical reactions and mineral neo-formation to occur. This is the first described englacial diagenetic mechanism occurring in deep Antarctic ice and supports the ice-weathering model for jarosite formation on Mars, highlighting the geologic importance of paleo ice-related processes on this planet. Additional implications concern the preservation of dust-related signals in deep ice cores with respect to paleoclimatic reconstructions and the englacial history of meteorites from Antarctic blue ice fields.

Ice Core, DNA and Biodiversity on the Alps
Current biodiversity loss is a major concern and thus biodiversity assessment of modern ecosystems is compelling and needs to be contextualized on a longer timescale. In this ice core study, a collaboration between Fondazione Mach (Italy) , Uppsala Univerity (Sweden), MUSE Trento (Italy) and Eurocold Lab, University of Milano Bicocca (Italy), we tested, for the first time, the potential of HTS to estimate plant biodiversity archived in the surface layers of a temperate alpine glacier, amplifying the trnL barcode for vascular plants from eDNA of firn samples. Results highlighted the presence of pollen and plant remains within the distinct layers of snow, firn and ice. DNA metabarcoding described distinct plant species composition among the different samples, with a broad taxonomic representation of the biodiversity of the catchment area and a high-ranking resolution. New knowledge on climate and plant biodiversity changes of large catchment areas can be obtained by this novel approach, relevant for future estimates of climate change effects.

A 3800 year-long radiocarbon-dated and highly-resolved palaeoecological record from Lake Fimon (N-Italy) served to investigate the effects of potential teleconnections between North Atlantic and mid-to-low latitudes at the transition from Marine Isotope Stage (MIS) 3 to 2. The high median time-resolution of 58 years allows the identification of five abrupt event-boundaries (i.e., main forest expansion and decline excursions) synchronous with the sharp stadial/interstadial (GS/GI) transitions within dating uncertainties. During Heinrich Stadial 3 (HS 3) we reconstruct more open and dry conditions, compared to the other GS, with a dominant regional scale fire signal. Linkages between local fires and climate-driven fuel changes resulted in high-magnitude fire peaks close to GI/GS boundaries, even exacerbated by local peatland conditions. WThe authorse hypothesise that this signal, broadly resembling that of other mid-latitudes proxies, may be attributed to the southward shift of the Northern Hemisphere storm tracks and the associated delayed iceberg discharge events as documented during other HS.

Baccolo et al., 2020. Jarosite formation in deep Antarctic ice provides a window into acidic, water-limited weathering on Mars
Many interpretations have been proposed to explain the presence of jarosite, a ferric-potassium hydroxide sulfate [KFe3+3(SO4)2(OH)6], within Martian surficial sediments, including the possibility that it precipitated within paleo-ice deposits owing to englacial weathering of dust. This is the first described englacial diagenetic mechanism occurring in TALDICE ice core, and supports the ice-weathering model for jarosite formation on Mars, highlighting the geologic importance of paleo ice-related processes on this planet.

These results presented in this book highlights of some of the most recent advances in cryospheric studies, especially in relation to mineral dust and aerosols in the atmosphere. They evidence the complexity of chemical–physical processes involving solid compounds occurring in glacier, snow, and permafrost environments, covering different aspects such as spatial and temporal trends, as well as the impact of the mineral and non-mineral particles. These studies also demonstrate the need for collaborative interdisciplinary and transnational efforts to better understand the challenges of the present climatic and environmental research studies on Earth, but also out of the Earth’s system. The results show that recent advances in measurement techniques and source apportionment are powerful and sophisticated tools that may provide novel high-quality scientific information but represent only the first challenging step.
