Continents, countries, sea regions of the world.
This dataset comprises measurements from moored Acustic Doppler Current Profiler (ADCP), collected by the 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. The 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 ADCP mounted at different depths (782, 740 and 488 m depth) between the 2019 and 2023 measures the sea-water currents intensity and direction along the water column.

Fractional snow cover - Broggerdalen (PASSES)
Terrestrial Photography ApplicationS on Snow covEr in Svalbard (PASSES) Evolution of the fractional snow cover in the Broggerdalen area using ground-based cameras located at the Climate Change Tower. Development of a new snow product focused on the estimation of the fraction of snow cover in selected sites at different spatial resolutions. All the available data obtained from public repositories such as the digital elevation model of Svalbard, the webcam imageries in Svalbard and satellite products from Landsat, Sentinel and MODIS missions, will be integrated in order to estimate the fraction of snow cover, at different spatial resolutions, for each satellite mission, computed at different sites in Svalbard islands.
Processed images obtained by time-lapse cameras, data are orthorectificated and classified using spectral similarity and blue thresholding.

Homogenized Tethered Balloon record at station Ny-Ålesund, Spitsbergen in 2018 (BC-3D)
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.

Aerosol Flux in Arctic (ALFA) Evaluate aerosol dry deposition/emission in the Arctic on icy/snowy surface and its dependence on particle size and micrometeorological parameters. The measures of the particles exchange rate will be carried out with the technique of eddy-correlation at Ny Alesund in size-segregated mode (2-3000 nm) coupling a sonic anemometer, a CPC and an optical particle counter (OPC) that are able to detect fluctuations of the particles concentration at high frequency (1Hz).

Glacial drainage physical-chemical parameters (ISMOGLAC)
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.
