Most of the scientific activity of the researchers of the Institute of Polar Sciences makes use of three permanent scientific bases located in the polar areas: the Dirigible Italia Station (SDI) located at the Svalbard Archipelago, in the Arctic and the Mario Zucchelli (MZS) and Concordia stations in Antarctica, respectively in the Terranova Bay and at Dome C, on the Antarctic Plateau.
The Dirigible Italia Station is managed by the CNR through ISP. The Mario Zucchelli Station is managed by ENEA for PNRA, while the Concordia base, opened on the basis of a bilateral Italian-French agreement between PNRA (Italy) and IPEV (France), is managed jointly between ENEA and IPEV.
Where we are: the secondary office of the Institute of Polar Sciences of Bologna is located in the Research Area of Bologna. The ISP occupies a total area (offices and laboratories) of about 300 m2, distributed between 2 buildings, that are partly shared with ISAC (Institute of Atmospheric and Climate Science) and ISMAR (Institute of Marine Sciences) staff.

Research Topics
Introduction
The ISP’s research activities are mainly carried out in the Antarctic and Arctic Regions where snow and ice are the dominant aspects of the landscape. These regions, more than others, are affected by climate change and because of this the work of scientists has become a real race against time to be able to learn more about the history of our planet in order to understand how human activities, from the dawn of civilization to present day, have impacted ecosystems, by interacting with and modifying the delicate balances that govern the Earth’s climate system.
Brief description
The experimental activities carried out at the MAMB laboratory in Messina are aimed at the ecological study of microorganisms by applying specific methods for the determination of the abundance and biomass of prokaryotes (Bacteria and Archaea) and phytoplankton, as well as for the morphometric and morphological description at the cellular level. The evaluation of these phenotypic characteristics provides a different approach to the analysis of the ecosystem structure and allows to evaluate the heterogeneity of natural populations. Variations in cell size, shape and morphology are considered sensitive indicators of trophic and climatic changes in ecosystems. The laboratory also carries out analyzes for the quantification of viable (Live / Dead) and respiring (CTC +) cells using specific microbial biomarkers. The laboratory activities are also in support of the EcoBiM and BiogeM Laboratories.
Matrices of interest
The matrices analyzed are mostly attributable to the hydrosphere (marine, river and lake waters, brines), soil, sediments, biofilm, cryosphere (permafrost, snow, sea and continental ice, intrapermafrost brines) and aquatic organisms.
Applied experimental approaches
- determination of biomass of prokaryotes by counting, and morphometric and morphological analysis of cells, using selective filters for DAPI (4 ', 6-diamidine-2-phenylindole);
- determination of cells with primary fluorescence using specific selective filters;
- quantification of cells endowed with respiratory activity (5-Cyano-2,3-ditolyl-tetrazolium chloride-CTC), using selective filters for rhodamine;
- quantification of viable cells with intact membranes (Live / Dead) using selective filters for fluorescein and rhodamine;
- identification of target bacterial cells by immunofluorescence techniques (fluoresceinated antibodies);
- estimation of the relative abundance of microbial phylogenetic groups using CARD-FISH (catalyzed reporter deposition-fluorescence in situ hybridization).
Instrumentation
- Zeiss AXIOPLAN 2 Imaging epifluorescence microscope equipped with AXIOCAMHR (Zeiss) digital video camera and AXIOVISION 3.1 software.

Short description
The experimental activities carried out at the BioSoundEcology Lab in Messina are focused on the analysis of biological underwater acoustic sources and the study of the ecological dynamics of marine vertebrates and invertebrates in polar habitats. In addition, the impacts of anthropogenic acoustic sources on the ecology, physiology and behaviour of marine organisms are assessed. In particular, through the study of the sounds generated by animals, the biological and ecological aspects are investigated. The analysis of the noise from human activities provides useful elements for understanding the effects on animals through the study of their behavioural and physiological responses.

Short description
The research activities carried out in the BiogeM laboratory at the Messina headquarters are aimed at studying the marine and terrestrial biological processes that modulate and influence the chemical characteristics of the polar environment and the related cycles of matter and energy, also in relation to climate change.
Particular attention is paid to the evaluation of the role of microorganisms in the global carbon cycle and in the biogeochemical cycles of nutrients (nitrogen, phosphorus) of marine and lacustrine environments, through the study of both productive and degradative processes.
Among these, the activities involved in the decomposition of organic polymers, through microbial enzymatic activities, and the mineralization processes through microbial respiration.
The biogeochemical processes mediated by the microbial component are also being studied in the framework of the cryosphere, in order to understand the ecological significance of microbes in the permafrost, and their ability to maintain an active metabolism in extreme living conditions.
Together with the microbial processes linked to the biological pump and organic matter decomposition, a series of indirect biogeochemical parameters related to phytoplankton and bacterial biomass (Chlorophyll, ATP, lipopolysaccharides-LPS) are also determined.
Matrices of interest
The analyzed matrices are mostly ascribable to the hydrosphere (marine, river and lake waters, brines), soil, sediments, biofilm, cryosphere (permafrost, snow, sea and continental ice, intrapermafrost brines) and aquatic organisms.
Study techniques
At the BiogeM laboratory, measurements are carried out to determine the following parameters:
- Primary phytoplankton production;
- Microbial respiratory activity (consumed O2; produced CO2) (by ETS assay);
- Microbial enzymatic activities (leucin aminopeptidase, beta-glucosidase and alkaline phosphatase) (through fluorogenic substrates);
- Heterotrophic bacterial production;
- Content of total and size-fractionated (pico-, nano- and micro-phytoplanktonic) chlorophyll-a, pheopigments;
- microbial ATP in pico-, nano and microplankton fractions;
- Quantitative analysis of lipopolysaccharides (LPS) by the LAL chromogenic test.

Brief description
Experimental activities carried out at the EcoBiM LAB in Messina are addressed to the ecology and biotechnology of microorganisms, particularly prokaryotes, inhabiting both marine and continental polar habitats. The diversity of microorganisms, their response to environmental stress conditions (deriving from natural or anthropogenic forcing, such as climate change and chemical contamination), the astrobiological implications of life in extreme environments, and their evolution and adaptation in polar environments are among the ecological aspects investigated. EcoBiM researchers are also interested in the evaluation of the metabolic capabilities and biotechnological potentialities of cold-adapted microorganisms, by searching for biomolecules exploitable in industrial applications and bacteria able to degrade organic pollutants at low temperatures.
Matrices of interest
The analyzed matrices are mostly attributable to the hydrosphere (marine, river and lake waters, brines) and cryosphere (permafrost, snow, sea-ice and continental ice, intrapermafrost brines), but soils and sediments are also considered. The study of the interactions between microorganisms and biotic (for example, pelagic and benthic organisms) and abiotic (such as microbial communities colonizing polymeric materials, indicated with the term plastisphere) is of particular interest.
Applied experimental approaches
For the microbiological characterization of extreme environments, similarly to the analytical procedures commonly applied for the study of temperate areas, we use both culture-dependent and -independent (i.e. biomolecular and biochemical) approaches, including:
- isolation and maintenance in pure culture of bacterial strains;
- phenotypic (physiological, biochemical and morphological characteristics) and genotypic (analysis of the 16S rRNA sequences and search for functional genes) characterization of cultivable bacteria;
- screening of bacteria for the production for useful biomolecules (including antibiotics, exopolysaccharides, biosurfactants);
- evaluation of the metabolic capacities of the microbial communities through miniaturized assays;
- characterization of the microbial communities by the hybridization in situ with oligonucleotide probes (CARD-FISH);
- extraction of environmental DNA and RNA for metagenomics and metatrascriptomics studies;
- preparation of microcosms enriched with organic and inorganic contaminants, and degradation tests.
Instrumentation
The EcoBiM LAB is equipped with basic instrumentation for environmental and applied microbiology (laminar flow cabinet, autoclave, incubators and thermostated baths, centrifuges, filtration systems, sonicators, spectrophotometers, fluorometers) and molecular biology equipment (thermocycler and equipment for electrophoresis).

Polar environments are highly biodiverse on a spatial temporal scale as well as at different levels of biological organization, from the molecular level to the entire ecosystem. Recent and rapid climatic and environmental changes give urgency to understanding the response of biological communities to these changes, and their impact in the short and long term. In this context, ISP researchers study the different bio-ecological aspects of the marine and terrestrial ecosystems of both poles. Their research is developed along four main often interconnected research fields.
Biodiversity and adaptation
Polar biological communities are heavily influenced by several local factors concomitant to low temperatures, such as dryness, ice cover, poor nutrient availability, exposure to harmful solar radiation (e.g. UV-B radiation), extremely variable light periods and, in specific cases, high salinities and osmotic stress. Biodiversity guarantees the functioning of all ecosystems, so studying the properties and temporal evolution of polar ecosystem is fundamentally important for improving our knowledge of its current state and predicting its future development, particularly in the light of climate change. The analysis and monitoring of the biodiversity of biological communities and their ecological dynamics constitutes the focal point of this research topic. The study of the morphological-functional adaptation mechanisms adopted by polar organisms for survival in extreme conditions is particularly interesting.
Deeper understanding of biological processes and recent advances in biotechnology allow us to use the natural world to progress in various industries, such as in the development of drugs and food additives. In general, the term bioprospecting is used to indicate the exploration of living beings and biological materials for biomolecules that may be useful to humans. In this field, poorly known or poorly described genetic resources have a great potential for the discovery of new and valuable natural products. Therefore, polar organisms, given their unusual metabolic abilities and physiological adaptations to extreme environmental conditions, are well suited for this purpose. Furthermore, the possible future potential of polar organisms in of the bioremediation of pollutants, even persistent ones, at low temperatures should not be overlooked.
Where we are
The building, in pure Art Nouveau style, is located on the Straits of Messina, in the shadow of the Montorsoli Lantern. Thanks to this position, it dominates the waters of the Straits and the Port. The building consists of a central body with three floors, which houses offices and studios, and two wings, with the laboratories. The ISP building in Messina is shared with the Institute for Biological Resources and Marine Biotechnologies (CNR-IRBIM) and there is also a park of about 10,000 square meters, where there is the main auditorium in a building that was originally the Royal National Shooting range.

M. Sc. in Environmental Sciences, Ph.D. in Environmental Sciences (oceanography) from the University of Venice. Research Director at the CNR Institute of Polar Sciences, Venice, CNR Researcher since 1997. From 2019 to early 2025, he held the role of Head of the Research Division at NATO STO CMRE in La Spezia.
He taught classes at the University of Bologna, Ancona, and Bocconi University in Milan, and owns the National Scientific Qualification as Full Professor in the 04/A4 Geophysics sector. Awarded the Office of Naval Research Command Coin, he served as Deputy President of the Ocean Science Division at the EGU (European Geoscience Union) from 2019 to 2024. In 2022, he received the Tridente d’Oro award for scientific and outreach merits and, starting in 2024, was admitted as an International Fellow of The Explorers Club.
He investigates the relationship between oceans and climate with a multi- and interdisciplinary approach. His main area of interest is physical oceanography and the interactions occurring between atmosphere, water and sediments. His research has focused on understanding and numerically modeling the role of currents, winds and waves in the transport of heat and salt in the oceans, and the associated variability in the context of an evolving climate.
The extraordinary role in the redistribution of energy between oceanic and atmospheric masses, and the determination of the related energy transfer along the water column, has been central to his research activities, intertwined with connections to: biogeochemical and sedimentological aspects (transport of nutrients and associated sediments); marine renewable energies; unexploded ordnance in the sea; and risks related to flooding and coastal erosion. He has promoted and developed a series of 3D circulation models coupled with meteorological models, third-generation wave generation and propagation models, and modules for the transport of non-cohesive sediments and biogeochemical modules.
The modeling approach has been validated with data from satellites, remote observations, and in-situ measurements in particularly vulnerable areas in the context of global warming. Along with the use of CTD probes, wave gauges, current meters, and turbidimeters, innovative techniques such as Maritime Unmanned Systems (MUS), seismic oceanography, and turbulence measurements with free-fall profilers have been employed. Author and co-author of over 120 papers in ISI journals with Impact Factor, 2 CNR patents, and 5 popular science books, he is a member of the Editorial Board of Scientific Reports (Nature group), Progress in Oceanography, and Ocean Dynamics.

High Performance Liquid Chromatograph Agilent 1100 Series HPLC Systems
Brief description
The HPLC-MS/MS system allows to quantitatively determine polar organic compounds in several environmental and vegetable matrices and biota samples. It is commonly used to investigate specific markers of sources or environmental processes in samples collected in polar regions. It is used to determine levoglucosan, key tracer of biomass burning, in ice core samples to provide historical profiles of fire regimes in paleoclimatic studies. Several water soluble organic compounds (free and combined amino acids, phenolic compounds) are determined using HPLC-MS/MS in aerosol samples to define chemical composition of atmosphere in urban and polar samples. Polar pesticide or toxins are commonly determined with HPLC-MS/MS in fresh water, sea water, biota or vegetable samples.

Mercur Plus - Analytik Jena AG, cold vapor atomic fluorescence spectroscopy (CV-AFS).
Brief description
Cold vapor atomic fluorescence spectroscopy (CV-AFS) is an analytical technique used for the quantification of mercury at trace/ultra-trace levels. This technique is mainly used on “clean” aqueous matrices (eg ice, snow, and water) from remote and uncontaminated areas.
The sensitivity of the instrument is fully harnessed by using official methods such as USEPA1631 version E or UNI-EN 15853: 2010. The Hg present in the matrix is oxidized to Hg2+ with BrCl solution and then reduced to elemental mercury(Hg0) con SnCl2. The Hg0 is stripped from the aqueous matrix using an inert carrier gas (argon) and successively transported to gold traps for the pre-concentration by amalgam formation. Following thermal desorption at T between 450-500 °C, the Hg0 is desorbed from the gold traps and is transported into a quartz cell.
Light from a mercury vapor lamp passes through the quartz cell that contains the sample mercury in a flow of argon carrier gas and excites all the mercury atoms which then emit a characteristic fluorescence radiation at 253.7 nm. The amount of light emitted by the mercury atoms in the sample is proportional to the amount of mercury passing through the quartz cell. The CV-AFS of the CNR-ISP is located inside a dedicated clean room.

Gas chromatograph coupled with mass spectrometer (GC-MS)
Brief description
The GC-MS system allows the quantification of volatile apolar compounds in environmental matrices. In the environmental field GC-MS finds main application in the determination of persistent organic pollutants (POPs) such as PCBs, PBDEs, PAHs, pesticides, in environmental matrices both in urban and remote areas such as polar areas. As well as it used in the determination of personal care products such as fragrances that have been observed not only in urban areas but also in Antarctica.
In the ISP-CNR there are 3 GC-MS systems. Among these, the system equipped with a cryogenic trap allows the preconcentration of volatile compounds (allowing the quantification of volatile compounds difficult to analyze in GC even at very low levels). There is also a GC-MS system equipped with a pyrolyser that allows the analysis of non-volatile materials such as plastic materials.
