Arctic Present Climate Change and Past Extreme Events (ARCA) Tephra are volcanic particles that can be used as chrono-stratigraphic tool for correlating sedimentary archives once they have been identified. Marine sediments have been analyzed from the GS191-01 PC core recovered during the PREPARED CRUISE 2014 in the Arctic Sea (western of Svalbard Islands). Some of these samples resulted positive and geochemical analyses will be perfomed to determine the volcanic source and establish possible correlations with known eruptions.

Temperature, electrical conductivity, hydrometric level measured in piezometers located near CCT (Ny-Alesund). The data were generated thanks to the following funding sources: ICEtoFLUX (2022 to 2025) and UNDER (2025).

This dataset comprises measurements from thermistor (SBE56) mounted on the Mooring Dirigibile Italia (MDI), which is managed by the Institute of Polar Sciences of the National Research Council (CNR). The mooring is placed in the Kongsfjorden, Svalbard Island, since September 2010 and the thermistor is placed at the nominal depths between 51 and 59 m and is operative from September 2012. 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: sea-water temperature. 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.

ISotopic and physical-chemical MOnitoring of GLACial drainages and sea water in the Ny-Ålesund area (Svalbard) The data are related to in-situ measurements of the physical-chemical parameters (temperature, electrical conductivity, pH, alkalinity), performed by portable device during summer period, starting from the higher sector of the glaciers (Midtre Lovenbreen, Austre broggerbreen, Vestre Broggerbreen, Kongsvegen, Pedersenbreen), where the first melt water is encountered, continuing towards the glaciers terminus, both laterally and centrally, and downstream, on the proglacial rivers, up to the sea.

Ionospheric Scintillations Arctic Campaign Coordinated Observations (ISACCO) The aim of ISACCO is to perform a scintillation measurements campaign by a GNSS Ionospheric Scintillation and TEC Monito) at Ny-Ålesund and Longyearbyen (Svalbard, Norway). The System consists of dual-frequency receiver with special firmware specifically configured to measure amplitude and phase scintillation. Starting from the end of 2015 a Septentrio PolaRxS_PRO receiver has been installed in one of the two observation sites in Svalbard, NyÅlesund, for the observation of all the available satellite constellations GALILEO, GPS, GLONASS at the Svalbard longitude.

Aerosol scattering coefficient at 1 wavelength (530 nm) measured using a nephelometer M903 and absorption coefficient at 3 wavelengths (467, 530, 660 nm) measured using a Particle Soot Absorption Photometer (PSAP), both manufactured by Radiance Research.

LIQUIDICE Project start: 2025-02-01 - end: 2029-1-31 The estimation of the Fractional Snow-Covered Area in the Brøgger Peninsula ensambling processed imagery located at different sites with different spatial resolutions. This dataset will be aimed to support the estimation of cryospheric information using remotely sensed data. The Ensembled FSCA retrievals are obtained, at the moment, by terrestrial photography applications established at the Amundsen-Nobile Climate Change Tower, at the Zeppelin observatory and at the Gruvebadet Snow Research Site in the Kongsfjorden area. This is the legacy of the Snow Core Data (SnowCorD) project that has been included in the activities contributing the LIQUIDICE project.

RIS: 11028 Spatial Distributions of Black Carbon and Mineral Dust in Air and Snow Surface Layers upon Svalbard Glaciers (BC-3D) Project Start: 2018-03-01 End: 2020-06-30 The scientific goals of BC-3D are to evaluate the distribution of Black Carbon and Mineral Dust in the first layers of atmosphere and surface snow over targeted Svalbard glaciers in order to identify the mechanisms of the air/snow exchanges also assisted by model predictions to provide the full 3D picture. Aerosol vertical profiles gridded at a 50 m spatial resolution: R, T, P, RH, Aerosol size distribution, BC concentration. Maximum altitudes 1500 m.
