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).

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.

Arctic Present Climate Change and Past Extreme Events (ARCA) CD4 core was micromilled at 200 μm increments using a micro-milling method (Drysdale et al., 2012). The stable isotope composition of the powders was measured on CO2 gas released by reaction with 105% H3PO4 at 70°C, which was measured using a mass spectrometer. Isotopic results are reported using the conventional δ-notation in per mille (‰), with reference to the Vienna Pee Dee Belemnite (V -PDB) standard. Instrument : MC-ICPMS, Nu-Instruments Plasma, Finnigan GasBench Parameter : Th**230/U**238 and U**234/U**238 activity ratios, (δ**13)C and (δ**18)O

ISotopic and physical-chemical MOnitoring of GLACial drainages and sea water in the Ny-Ålesund area (Svalbard) The project concerns an isotopic and physical-chemical monitoring of inland glacial drainages and ocean water into Kongsfjorden. It is aimed at defining the dynamic processes of the glacial melting and evaluating the consequent transfers of fresh water towards the Arctic Ocean. The dataset includes the continuous measurements (1 data/15 min) performed during summer season by a CTD diver. Parameter: Temperature, electical conductivity, water level.

Arctic Present Climate Change and Past Extreme Events (ARCA) Analysis of RES datasets available. Production of thematic maps of representative ice-calving effect in some Greenland outlet glaciers. Development and upgrade of INGV RES system.

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]

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

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.

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.

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).
