Mixing state and organic volume fractions of sub micron aerosol particles collected at the Zeppelin observatory

Brief narrative summary of the content of the resource(s)

This dataset comprises measurements from a moored single-point acoustic current meter, 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 10 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: subsurface temperature and subsurface currents. 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.

Snow sampling every week near Gruvebadet (Svalbard)

Chronobiology of polar organisms (Chronopolar) Monitoring water parameters in surface and deep (3.0 meters) using DS18B20 + rasberry-pi. Sample collection: Lepidurus arcticus.

The Climate Change Tower Integrated Project (CCT-IP) represents the guide lines of the italian research in the arctic and aims to study the interaction between all the components of the climate system in the Arctic. The Amundsen-Nobile Climate Change Tower (CCT) is the key infrastructure of the project, and provides continuous acquisition of the atmospheric parameters at different heights as well as at the interface between the surface and the atmosphere. Precipitation data (liquid and solid) are obtained from an optical disdrometer (Vaisala FD70). Partly funded by Arctic PASSION project (agreement number 101003472). Data are available under request.

Monitoring of Aerosol: Short and Long range source areas related to Climate Change (MAShLoCC) During the Arctic campaign 2010, an atmospheric aerosol sampling at the Gruvebadet observatory has been carried out in order to obtain information about the formation and composition of atmospheric aerosol, transport processes toward the Arctic zone as well as local and remote source areas. Instrument : ICP-SFMS, IRMS, Orbitrap

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 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.

Climate-Cryosphere-Carbon interactions in Kongsfjorden, Svalbard (C3) Use sediment cores as archives of climate-induced destabilizations in the fjord. By targeting well known past climate changes (MWP and LIA) we will understand how the C3 system varied during natural warming and cooling events. Retrieve of two sediment cores in Kongsfjorden, in summer 2017, to encompass the last 1k years.
