This dataset comprises measurements from moored multiparametric probe, collected by the Aldo Pontremoli Mooring (MAP), which is managed by the Institute of Polar Sciences of the National Research Council (CNR). 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, 2020. The instrument collect a wide array of physical and biogeochemical Essential Ocean Variables, including seawater pressure, temperature, conductivity, salinity, dissolved oxygen concentration and pH. 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

Time series acquisition of biogeochemical parameters along the water column along the mooring MAP
Short-term dynamics of nutrients, planktonic abundances, and microbial respiratory activity in the Arctic Kongsfjorden
Atlantification of Arctic ocean is causing a sharp increase in temperature and salinity around Svalbard Islands and in Kongsfjorden. Such phenomenon and the input of sediment-rich glacial meltwater influence salinity, water column turbidity, and light penetration with ecological implications on the microbial features.

Snow sampling every week near Gruvebadet (Svalbard)
Water soluble compounds in annual and seasonal aerosols using an high volume Andersen sampler
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.
This dataset comprises measurements from moored sediment trap, collected by the Mooring Dirigibile Italia (MDI), which is managed by the Institute of Polar Sciences of the National Research Council (CNR). The data was gathered at Kongsfjorden, Svalbard Island, since 9 September 2010. This dataset is also part of the SIOS-Svalbard Integrated Arctic Earth Observing System, developed to observe the impacts of climate change, including the rapid loss of sea ice cover, the retreat of local glaciers, and the Atlantification of Arctic seas. Measured properties are: Total Sedimentation flux , Sedimentation flux of organic carbon in the water column, Sedimentation flux of total nitrogen in the water column, Sedimentation flux of CaCO3 in the water column, Sedimentation flux of non-metallic inorganic species (opal) in the water column, Sedimentation flux of Organic Matter in the water column, Sedimentation flux of lithogenic fraction in the water column. The zooplankton swimmers and sinkers collected by sediment traps are analysed in term of composition and morpho-functional traits.

moorings activities in the Kongsfjord since 2010
This dataset comprises measurements from S1 Mooring, which is managed by the Institute of Polar Sciences of the National Research Council (CNR) and National Institute of Oceanography and Applied Geophysics (OGS). The data was gathered on the Fram Strait south of the Spitsbergen in an open-sea area strongly influenced by both the interaction between Atlantic (northward-moving) and Arctic (southward-moving) waters as well as by the presence and winter formation of sea ice and atmospheric forcing. To understand these dynamics, a deep-water oceanographic S1 Mooring was anchored at about 1040 meters depth, since June 2014 and is part of the SIOS-Svalbard Integrated Arctic Earth Observing System, developed to observe the impacts of climate change, including the rapid loss of sea ice cover, the retreat of local glaciers, and the Atlantification of Arctic seas. The CTD sensor mounted at 785 m measures sea-water temperature and salinity. The acquisition of this time series data is still ongoing and will continue, bolstered by the inclusion of this infrastructure within the framework of the Italian PNRR project ITINERIS. This ensures sustained data collection and further enhances our understanding of the observed environmental changes.

moorings activities in the Fram Strait since 2014
pH tipping point in Svalbard (pHinS) The project is focused on carbonate chemistry in the fjord and measure how meltwater, icebergs and freshwater runoff affects the acidity of coastal seawater. Acquisition of CTD profiles and seawater samples at discrete depths (surface, bottom and 1-3 intermediate depths) to determine pH, total alkalinity, dissolved inorganic carbon, dissolved oxygen, nutrients, dissolved organic carbon. Collection of samples from icebergs and streams to determine the same set of parameters measured in the seawater. Some of the analysis were performed in the laboratory of the “Dirigibile Italia” Arctic station soon after the collection; others will be performed on preserved samples in ISMAR’s laboratories. 62 water column profiles of pressure, Temperature, salinity, dissolved oxygen, turbidity instrument: SBE19plus

Isotopic siganture of snow 2017 and physical-chemical, chemical and isotopic data of Kongsfjorden water (ISMOGLAC)
ISotopic and physical-chemical MOnitoring of GLACial drainages and sea water in the Ny-Ålesund area (Svalbard) (ISMOGLAC) Sampling and in-situ measurements on snow and water, performed into both Kongsfjorden and glacial streams that originate in supraglacial, englacial and subglacial zones of different glaciers (Midtre Lovenbreen, Austre broggerbreen, Vestre Broggerbreen, Kongsvegen). Dataset concerns water isotopes signature of snow and Kongsfjorden water and physical-chemical data of the latter.
