Sampling of PM10 aerosol using a cascade impactor to define the chemical composition in six different size stages. The quartz filters were extracted with ultrapure water and water soluble species were determined: major ions, MSA, carboxylic acids, amino acids, sugars, phenolic compounds, and other organic water-soluble emergening pollutants.

Daily averages of equivalent black carbon from aerosol absorption coefficient at 660nm measured using a Particle Soot Absorption Photometer (PSAP), manufactured by Radiance Research. MAC equal to 10 m^2/g.

The Italian project CASSANDRA is part of the international framework of the Synoptic Arctic Survey which seeks to collect oceanographic data in the Arctic Ocean in the two-year period 2020-2021 involving the coordination of many research vessels belonging to different nations. The aim is to determine the current state and major ongoing changes in the Arctic marine system by generating an oceanographic dataset that allows for a comprehensive characterization of Arctic hydrography and circulation, carbon uptake and ocean acidification, the distribution of possible pollutants, the functioning and productivity of organisms and ecosystems.

Cyclone Sample collection Teams collect two weekly 24-hour samples Teams create metadata by scanning QR codes on cyclone sampler and sample vial with Lifeplan app Teams store samples until shipment in a freezer - Sample shipping to Sweden - Sample cleaning by Lifeplan - Sample shipping to Guelph - Sample sequencing - Transfer of sequencing data to Lifeplan - Bioinformatics - Species lists Through LIFEPLAN, we aim to establish the current state of biodiversity across the globe, and to use our insights for generating accurate predictions of its future state under future scenarios. In LIFEPLAN, we thus characterize biological diversity through a worldwide sampling program, and develop the bioinformatic and statistical approaches needed to make the most out of these data.

The Aldo Pontremoli Mooring (MAP), operated by the Institute of Polar Sciences of the National Research Council (CNR), has been active in the Kongsfjord, located in the Svalbard archipelago, since September 11, 2020. It is situated near the mouth of Bayelva River mouth and is influenced by land terminating glaciers and the release of permafrost. Currently, the mooring line is equipped with various instruments positioned at depths ranging from 22 to 97 meters within the water column. These instruments collect a wide array of physical and biogeochemical Essential Ocean Variables, including seawater pressure, temperature, conductivity, salinity, currents, dissolved oxygen concentration, pH, particle fluxes and dissolved carbon dioxide concentration. This activity is part of the Svalbard Integrated Arctic Earth Observing System (SIOS), which aims to monitor the impacts of climate change, such as the rapid loss of sea ice cover, the retreat of local glaciers, and the Atlantification of Arctic seas. Time series acquisition is ongoing and will continue, supported by funding from JRA ENI-CNR. The project's goal is to analyse the environmental feeback related to the material released into the marine environment due to permafrost melting. Reactivated permafrost can have significant consequences for both climate and the environment by contributing to the release of greenhouse gases into the atmosphere and pollutants into aquatic ecosystems.

This proposal will focus on eutrophication, contaminants, marine litter and underwater noise descriptors of the MSFD. Vertical acquisition in 18 CTD station in Kongsfjorden with water sampling at 2-3 depths (surface, intermediate, bottom) for nutrient and pH analyses of sampled water in the lab

Aerosol Biogeochemical cycles, Sources and TRansport processes in the climate-sensitive ArCTic - ABSTRACT Dataset consists in: Aerosol load, Ion, metal, EC/OC measurements on bulk and size-segregated particulate matter at Gruvebadet Observatory (Ny Alesund - Italian Station "Dirigibile Italia") using Aerosol sampling and measurement devices (TECORA ECHO-PM, TECORA Skypost, TECORA HI-VOL, FAI PBL, TSI SMPS, TSI APS - Ion Chromatographs, ICP-AES, Thermo-Optical Analyzer, ICP-MS) Aerosol measurements and sampling. Atmospheric Particle Size Distribution. SMPS (10-500 nm) and APS (0.5-20 um). PM10 aerosol low volume sampling for determination of ions and metals: continuous 24/48h resolution samplings. Multi-stage impactor (Dekati 4-stage: < 1 um - > 10 um) for measurement of ion composition: 4-day resolution sampling. PM10 medium volume sampling for determination of metal content and Pb isotope ratios: 4-d resolution samplings. PM10 on quartz filters for determination of Elemental od Organic Carbon (EC/OC): continuous 24/48 h resolution samplings. PM10 aerosol low volume sampling on PTFE for elemental determination by PIXE technique.

Timeseries recorded at the mooring S1, at nominal depth of 1000 m during different deployments. The scope of the measurements is to study the temporal variability of the thermohaline properties of the Norvegian Deep Water, and assosiated deep flow

Ice Nuclei Particle Concentration (INPAIR) INPAIR Svalbard' Chemistry and Physics of the Atmosphere: Ice nucleating particle (INPs) concentration obtained in spring and summer campaigns in the Arctic Region. Measurements of INPs concentrations and activation fraction of aerosol in Arctic (e.g. Gruvebadet observatory in Ny-Ãlesund). b) Correlating INPs concentration with meteorological parameters and physicochemical characterisations. Instrument: PM1 and PM10 sampling lines. DFPC chamber

Observing Earth critical zone processes in the Bayelva basin (CZO@Bayelva). Data represents the average values and the corresponding standard deviation of Net Ecosystem Exchange (NEE), Ecosystem Respiration (ER) and Gross Primary Productivity (GPP) obtained from two different sites in the tundra of the Bayelva river basin: One site (named CZ) is located in the vicinity of the Climate Change Tower. The other one (named "Airport") is in the vicinity of the Ny Alesund Airport. Each average value is obtained as a mean over a set of around 20 point measures for each plot and each sampling date. Flux data are complemented by measurements of soil temperature, soil volumetric water content, air temperature and relative humidity, and solar irradiance. CO2 fluxes are measured using a flux chamber and a LI-COR IRGA by means of the Dynamic Flux Chamber method.
