Microbial Ecology and Biotechnology LAB (EcoBiM)

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).

Microscopy and Preparation Laboratory (MiP Lab)

Brief description
Microplastics are considered emerging pollutants and they are present in different environmental compartments (e.g. seawater, soil, atmosphere, etc.). In 2019 the European Chemical Agency has clearly defined microplastics and their sizes: “a material composed of solid polymer-containing particles, to which additives or other substances may have been added, with particle dimensions ranging from 1 nm to 5 mm and with fiber lengths ranging from 3 nm to 15 mm and length to diameter ratio of >3. ECHA has also firmly stated the need of polymer identification when analyzing microplastics. Microplastics can be primary and secondary, according to their sources; sources of primary microplastics are discharges from household washing machines, road dust, tire wear and cosmetics. Particles and fibers of plastics can be vector of other pollutants and pathogens. An accurate quantification and characterization of microplastics allow evaluating the environmental risk assessment and designing future actions of environmental management and recovery.

Instrument
Micro-FTIR Nicolet™ iN™10 Infrared Microscope Thermo Scientific, it couples optic microscopy with IR spectroscopy. Two different detectors are present: DTG (Deuturate Triglycine sulfate) detector enables room temperature analysis, and MCT (Mercury Cadmium Telluride ) detector works with liquid nitrogen and allows the analysis of samples down to 10 µm. Samples can be analyzed on transmittance mode, reflectance mode and ATR mode.

Matrix and type of measurement
Non-destructive analysis of microplastics in different environmental samples (seawater, sediments, soil, permafrost, aerosol, snow, raw and treated water, discharges from household washing machines, etc.) and in different biota (crustaceans, mollusks, fish, etc.). Micro-FTIR allows quantification and simultaneous polymer identification of plastic particles and fibers and of additives, plasticizers. and other synthetic and natural fibers. It can be employed for analysis of microplastics, but also for analysis of microfossils, artistic handiworks, etc.

MDI

A permanent instrumented mooring has been installed in the inner part of Kongsfjorden (Svalbard Islands) at a depth of about 100 m with the aim of studying the intensity and composition of the flows of particles falling to the sea bottom, while monitoring the main physical properties of the water column. The mooring called Dirigibile Italia (MDI) was first installed in September 2010 and is serviced annually. The data acquired and stored by the various instruments are downloaded during maintenance, checked for QA/QC and uploaded to the Italian Article Data Center (IADC).
A 10-year time series of data for climate purposes is currently available.
MDI allows us to continuously monitor the variations of the thermohaline characteristics of:
a) surface water from glacier melting;
b) intermediate water that derives from the intrusion of Atlantic-type water;
c) bottom water produced locally during the winter.
Furthermore, through the collection of particulate matter, information is acquired on sedimentary processes and interactions between water and particulate matter with microzooplankton, glaciers and coastal runoff. The complex interplay between the processes that drive the input of native (marine) and alien (terrestrial) particles into Kongsfjorden has now been understood, some interpretations of possible future changes in particle flows for Arctic fjords in a warming scenario global can be suggested.

The oceanographic sensors on MDI are positioned along the mooring at different levels in the water column. The list of measured parameters includes:
- water temperature at 25, 36, 54, 62, 85 and 92 m
- speed and direction of currents at 37 and 93 m
- conductivity / salinity at 25 and 85 m
- turbidity and dissolved oxygen at 85 m
- total mass and particulate organic carbon flows at 83 m.
A hydrological survey is also performed every year, mainly during the summer, to obtain a seasonal picture of the spatial distribution of the different water masses in the fjord. For this purpose, a grid of about 15 stations is repeatedly measured for the main chemical-physical characteristics of the water masses: temperature, conductivity and turbidity.

MS1 and ID2

The water masses in the eastern Fram Strait are strongly influenced by the interaction between the Atlantic and Arctic waters, and by local atmospheric forcing. They clearly contribute to driving thermohaline circulation on a global scale. There is considerable variability in the system due to the different forcings (for example, atmospheric, internal, tidal, shelf dynamics) that play an important role, especially in the most superficial layer of the ocean. On the contrary, it is not entirely clear which processes are responsible for the inter-annual and seasonal variability of the deep flow in the western Spitsbergen offshore region.

To this end, in 2014 the oceanographic deep-sea mooring called MS1 was permanently installed, located southwest of Svalbard at about 1040 m depth (Lat. 76° 26.28'N Lon. 13° 56.91'E) in a joint effort between CNR and OGS. Long-term time series are essential for studying climate change, particularly in polar areas, which are extremely sensitive to global warming and sea / land ice melt. A twin mooring, called ID2, was placed 140 km north of anchor MS1 at approximately the same water depth in the years 2014-2016 and 2017-2018, in order to monitor spatial differences of in the properties and dynamics of the water along the Spitsbergen margin.

These undersea infrastructures represent the continuation of the experiment conducted in 2010-2011 as part of the EU-Hermione project with the launching of four moorings for one year along the Storfjorden continental slope to monitor the shelf-fjord exchanges and the platform dense water cascading events.

The MS1 and ID2 mooring are serviced annually by various research vessels (R/V Helmer Hansen, GO SARS, Polarstern, Alliance), and are supported by international collaborations and numerous projects/initiatives: EU-Eurofleets (PREPARED, BURSTER projects), the Italian PNRA program (DEFROST project). Since 2017, they are also supported by the IIM HIGH NORTH Italian Navy program managed by the Hydrographic Institute of the Navy (IIM) in collaboration with the Center for Maritime Research and Experimentation (CMRE-NATO).

Data from MS1 and ID2 were used to contribute to the first two issues of The State of Environmental Science in Svalbard - an annual report (SESS Report) published by SIOS (Svalbard Integrated Observing System) in 2018 and 2019 (SOA project). Mooring data are downloaded in delayed mode during mooring maintenance, checked for QA/QC and stored in the OGS NODC data center with connection to SeaDataNet. At present, the data on temperature, salinity, dissolved oxygen, turbidity and horizontal currents cover a time period from June 2014 to October 2019. Information on sedimentary processes and interactions with mesozooplankton, glaciers and coastal runoff are acquired by collecting the particulate that sinks along the water column using automatic sediment traps.

Oceanographic sensors are tied to different levels in the deepest part of the water column. The list of parameters measured in the MS1 anchoring in its most recent configuration (v2019) includes:
- water temperature at 894, 909, 984, 1009 and 1115 m
- speed and direction of currents at 909, 984 and 1015 m
- conductivity/salinity and dissolved oxygen at 1009 m
- total mass and particulate organic carbon fluxes at 1009 m.

The time series of temperature and salinity are checked by comparing them with the data of the CTD drops performed before and after maintenance of the mooring.
The main institutions involved are: CNR with CNR-ISP and CNR-ISMAR, OGS and IIM.

Moorings South Adriatic

Ancoraggi strumentati Sud Adriatico - ULTIMO TITOLO Ancoraggio Strumentato Permanente Adriatico (ex) MSA AGGIORAMENTO 2023

Description of Southern Adriatic Sea Observing Site

The southern Adriatic is the deepest part of the Adriatic Sea with a maximum depth of 1200 m. In its western side, surface waters coming from the northern Adriatic spread southward along the Italian coast, whereas the surface Ionian waters flow along the eastern margin of the basin. Below the surface layer, the MLIW (Modified Levantine Intermediate Water), from the Eastern Mediterranean basin, enters the Adriatic Sea on the eastern side of the Otranto Strait, at 200-600 m depth.
The southern Adriatic is a site of dense water formation. The Adriatic Deep Water (AdDW) is generated through deep vertical convection, caused by surface heat losses following cold continental wind events occurring in late winter. Occasionally, the North Adriatic Deep Water (NAdDW), produced by surface heat loss and evaporation driven by Bora storms during winter in the Northern Adriatic Sea, contribute to the AdDW. The NAdDW constitutes the densest waters of the whole Easter Mediterranean, it flows mostly along the western shelf of the central Adriatic Sea as a bottom-arrested density current and arrives to the Gargano Peninsula after 2–4 months since it has been produced. Recently shorter arrival times (3-4 weeks) have been observed. Once it reaches the edge of the continental shelf it sinks toward the center of the Southern Adriatic along the slope in front of the Gargano promontory or through the Bari canyon, carrying dissolved oxygen, nutrients, particulate matter, and pollutants to deep benthic ecosystems.

With the aim to monitor the arrival and the path of the dense waters coming from the northern Adriatic shelf, an observational system has been positioned based on three mooring lines: BB, EE and FF. This observational system has been activated and financed since 2004 by various scientific projects (EU-EuroSTRATAFORM, EU-HERMIONE, PRIN-OBAMA, EU-Perseus, EU-CoCoNet, Italian Flagship Project Ritmare (SP5-WP5-AZ3) and Italian Marine Strategy. In addition, these oceanographic moorings are part of the Italian Fixed Point Observatory Network (IFON) and, are supported by Planning and Grant Office of the CNR.
Since 2021, sites BB and FF, have become part of the European Multidisciplinary Seafloor and water column Observatory European-Research Infrastructure Consortium (EMSO-ERIC) as Regional Facility in the southern Adriatic Sea consisting of moorings BB and FF and observational site E2M3A operated by OGS Trieste. EMSO-ERIC is a European "diffuse" research infrastructure for ocean observation (https://emso.eu/), which enables long-term and also real-time monitoring of ocean processes. It consists of a system of Regional Facilities located at strategic marine sites in the European seas, Northeast Atlantic, Mediterranean Sea and Black Sea. Each site is equipped with multidisciplinary sensors placed on the seafloor and along the water column to continuously measure physical and bio-geochemical parameters that enable understanding and description of marine ecosystems, the monitoring of climate change, and provide information related to natural hazards. Participation in the EMSO-ERIC consortium also includes measurement of vertical fluxes of particulate matter, via of No. 2 sediment traps, in the deep mooring of the E2-M3A observatory (operated by OGS Trieste) located in the center of the Southern Adriatic Pit.

Participation in EMSO-ERIC is also supported by the activities of the consortium's Italian Joint Research Unit (https://www.emsoitalia.it/). Finally, the BB mooring is part of the Network of Long-term Continuous Measurements of Mediterranean Deepwater Temperature and Salinity (CIESM Hydrochanges Program).
The location of the sites was chosen upon the integration of morpho-bathymetric observations that defined the areas in which the passage of dense waters was more likely with forecasts based on the modeling of the outflow of the North Adriatic dense waters. The BB mooring is located in the northern branch of the Bari canyon, the EE mooring is located in an erosional area west of Dauno seamount, at about 1200m depth, and the FF mooring is on the continental slope in front of the Gargano promontory. Oceanographic sensors are fixed at different heights in the deepest part of the water column (Mooring BB).
The facilities are located offshore and can only be reached by ship. The nearest main docking port is Bari. Site BB is about 20 nm from the port, site FF is about 40 nm, site EE is 45 nm and site E2M3A is about 60 nm.
The instruments are equipped with internal memory and power supply. Oceanographic data are downloaded in delayed mode during mooring maintenance, which occurs semi-annually or annually. During maintenance, the moorings are retrieved to perform data offloading, trap sample collection, battery replacement, and functionality verification prior to redeployment. Such servicing have been performed using several CNR research vessels (R/V Urania, R/V Minerva Uno, and N/O G. Dallaporta) or ships of opportunity as part of the experimental activities of the aforementioned projects.
People involved: Stefano Miserocchi (stefano.miserocchi AT cnr.it), Leonardo Langone e Patrizia Giordano.

Data

Approximately six months after the servicing, data are available in their final form, following manual quality control procedures, metadata and storage in ISP-BO's internal data center. The acquired timeseries are post-processed to remove spikes, checked for consistency, and filtered to remove the effect of the tide (low pass filter). Periodic calibration of the sensors and comparison with measurements made from ship is also performed.
The data obtained, accompanied by metadata according to the conventions OceanSITES v1.4, SeaDataNet_1.0, COARDS and CF-1.6 are available in a plurality of formats (ASCII, NetCDF 3, NetCDF 4) through the ERDDAP data server: https://bo.isp.cnr.it/erddap/index.html.
The data produced by the South Adriatic observative site will also be available to the scientific community through the Data Portal of the EMSO-ERIC infrastructure, which includes appropriate visualization and representation tools.

Eight observatories report to the Institute of Polar Sciences, in various capacities: 6 in polar regions, of which 4 in the Arctic (Climate Change Tower, Gruvedabet and 2 Mooring: Kongfjorden and Storfjorden) and 2 in Antarctica (BSRN Station and Mooring del Ross Sea), and 2 in non-polar regions, of which 1 in the high altitude region (Col Margherita) and 1 in the Adriatic Sea (Mooring Southern Adriatic, MSA).

Organic Geochemistry Laboratory

GeoChem - lab overview In the Organic Geochemistry Laboratory at the Institute of Polar Sciences in Bologna, researchers and students deal with modern processes and paleo reconstructions by coupling the information provided by fossil biomarkers and stable carbon and nitrogen isotopes. Biomarkers and stable isotopes are geochemical proxies used to investigate the feedback mechanisms between the Earth climate and the biogeochemical cycles. The laboratory is equipped with various instruments to extract, purify and analyze a suite of different biomarkers, including terrestrial compounds (e.g. lignin phenols, aliphatic chain lipids, cutin-derived products) to understand land-ocean carbon exchange (e.g. permafrost thawing, river floods, etc.), alkenones for paleo-temperature reconstructions and highly branched isoprenoids for sea ice reconstructions. In addition, the laboratory is equipped with a Preparative Fraction Collector (Agilent-Gerstel) for the collection of individual compounds. This technique is especially useful for the radiocarbon analysis of biomarkers and can be very useful to derive an age model for the sedimentary archives and to investigate the processes related to permafrost thawing.

Facilities
The Organic Geochemistry Laboratory is equipped with several gas chromatographers and mass spectrometers for the analysis of carbon and nitrogen stable isotopes, measurement of carbon, hydrogen, nitrogen and sulphur content in organic matter and the extraction/quantification of organic biomarkers. The analytical facilities include:
- Thermo Fisher Scientiﬁc FLASH 2000 Element Analyzer coupled with a mass spectrometer DeltaQ (EA-IRMS)
- GC Agilent GC 7820-MSD EI 5977B
- GC Agilent 8860-FID G2790A

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.

Research Stations

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.

The ice-breaker R/V Laura Bassi

In 2019, thanks to a dedicated funding program by the Ministry of University and Research (MUR), Italy acquired a research ship with ice-breaking capabilities to conduct research activities in the polar regions. The research vessel was named after Laura Bassi, the first woman in the world to obtain an official academic professorship, and she did this at the University of Bologna in the 18th century.

The vessel is owned by the National Institute of Oceanography and Applied Geophysics (OGS) in Trieste and receives funds to conduct research activities from the National Research Program in Antarctica (PNRA). It also serves the polar scientific community thanks to an agreement between the major Research Institutes in Italy working in the polar regions and those managing the polar infrastructures (OGS, CNR and ENEA). The use of the R/V Laura Bassi has also been included in the strategic planning of the Italian Arctic Research Program (PRA).

The R/V Laura Bassi made its first expedition to the Ross Sea (Antarctica) in the austral summer of 2019-2020.
An extensive instrumental upgrade to the vessel is currently underway, with the contribution of the ISP staff, to convert it into a modern multipurpose scientific platform that can serve different scientific communities working on various research fields, including physical, chemical and biological oceanography, paleoceanography, geophysics, marine geology and atmospheric physics and chemistry.
