Snow and surface characteristics are monitored by CNR at the Climate Change Tower in Ny-Alesund.

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.

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.

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

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]

EEE@NYALESUND (EEENYA) The Dataset contains flux of cosmic rays measured at different locations at Ny Alesund. Each cosmic ray event will be tagged in time using GPS. Cosmic rays data will be correlated with atmoshperic conditions, also contained in the dataset. Measurement site: Ny Alesund: 1. Dirigibile Italia Station, 2. Gruvbadet laboratory, 3. close to the Amundsen-Nobile tower

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

DOC fractionation: dynamic of POPs and trace metals Arctic DOC (ArcticDOC) The sampling design is projected to cover almost five sampling points in the Kongsfjorden. The sampling of surface water (approximately 100 liters for each sampling point) and sediment are aimed at the determination of persistent and emerging contaminants: POPs PFAS, CUPs, PPCPs, endocrine disruptors such as nonylphenols and bisphenol A. At the same time, with tangential-flow ultrafiltration, dissolved organic matter (DOM) will be characterized according to size fractions (colloidal and truly dissolved) and the distribution of contaminants associated to these fractions will be evaluated.

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.

Measurements are obtained using a Pyrgeometer Kipp&Zonen, model CGR4, installed at Thule Air Base (220 m a.s.l.) in May 2013. The instrument sensitivity was determined during factory calibration for temperatures down to -40 °C, thus specifically suited for the polar environment. Data are acquired by a datalogger at 30 s time intervals and then transferred to a PC. The CGR4 and its dedicated PC are maintained by Daniela Meloni at ENEA.
