Snow and surface characteristics are monitored by CNR at the Climate Change Tower in Ny-Alesund. Partly funded by Arctic PASSION project (agreement number 101003472).

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).

Study of the noise generated by glaciers for quantification of geo-physical processes, wide band frequency acoustic recorders will be placed in the Kongsfjorden during the spring-autumn period. Moreover, the biological sound will be also collected and the interacting with the geo-physical and anthropogenic sounds will be evaluated. Instrument : SM2U.

This proposal will focus, by means of a multidisciplinary and well-balanced consortium 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. parameters: Pressure, Strain Gauge [db]rnTemperature [IPTS-68, deg C]rnConductivity [mS/cm]rnpHrnOxygen, SBE 43 [ml/l]rnTurbidity, Turner Cyclops [NTU] Pressure, Strain Gauge [db]rnTemperature [IPTS-68, deg C]rnConductivity [mS/cm]rnpHrnOxygen, SBE 43 [ml/l]rnTurbidity, Turner Cyclops [NTU]

ISotopic and physical-chemical MOnitoring of GLACial drainages and sea water in the Ny-Ålesund area (Svalbard) The dataset includes vertical profiles of physical-chemical performed on-site in different sites along the fjord in Kongsfjorden.

Atmospheric Gondola for Aerosol Profiles (AGAP) The scientific goals of AGAP are to develop novel aerosol payloads and evaluate the vertical distribution of aerosol properties in the Arctic Boundary Layer. Dataset consists in Aerosol vertical profiles gridded at a 50 m spatial resolution: R, T, P, RH, Aerosol size distribution, BC concentration, O3. Maximum altitudes 1500 m.

Ice Nuclei Particle Concentration (INP) Ice nucleating particle (INPs) concentration obtained in spring and summer campaigns in the Arctic Region. Sampling lines allow the aerosol particles collection onto the filters and the sampling line for the continuos measurements of size distribution with the OPC and SMPS. The aim is to improve our understanding of aerosol-cloud-climate interactions and representation of climate models.

Observing earth critical zone processes in the bayelva basin (CZO@Bayelva) The dataset includes CO2 fluxes measurements during summer period in different area along the transect from CCT to Ny-Alesund airport. The measures are performed using a portable accumulation chamber in dark (Ecosystem respiration, ER) and light (Net Ecosystem Exchange) condition. For each plot, about 20 measures are performed, including soil temperature and volumetric soil water content. CO2/H2O daily average values and standard deviation. Each measurement day contains a number of half-hour measurements.

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.
