Atlantification of Arctic ocean is causing a sharp increase in temperature and salinity around Svalbard Islands and in Kongsfjorden. Such phenomenon and the input of sediment-rich glacial meltwater influence salinity, water column turbidity, and light penetration with ecological implications on the microbial features.

Contribution of Vegetation and Soil components to Carbon cycle in Arctic environment in relationship to climate change (VegSoCA). Measurements of soil respiration and 13C labelling on different species in the experimental field close to the CCTower using LiCOR LI-8100. Species were: Carex rupestris, Dryas octopetala, Salix polaris, Moss and bare soil. Dataset: Species type, date, soil water content, soil EC, soil temperature, CO2 flux.

Ionospheric Scintillations Arctic Campaign Coordinated Observations (ISACCO) The aim of ISACCO is to perform a scintillation measurements campaign by a GNSS Ionospheric Scintillation and TEC Monito) at Ny-Ålesund and Longyearbyen (Svalbard, Norway). The System consists of dual-frequency receiver with special firmware specifically configured to measure amplitude and phase scintillation. Starting from the end of 2015 a Septentrio PolaRxS_PRO receiver has been installed in one of the two observation sites in Svalbard, NyÅlesund, for the observation of all the available satellite constellations GALILEO, GPS, GLONASS at the Svalbard longitude.

The dataset includes the sediment and biota sampling point in Svalbard Archipelago, along Krossfjorden and Kongsfjorden. Sediment was sampled with the grab from the MS-Teisten (Kings Bay) while amphipods were sampled from the coast with nets (Polar Circle - NPI).

Holocene environmental change on Svalbard (HOLS) The aim of this international umbrella project is to study the variation of environment and climate in Svalbard during the Holocene. At the moment no integrated temperature or precipitation record exists for the entire Holocene on Svalbard. We aim to reconstruct temperature and precipitation for the Holocene by using a combination of lake sediment records, proglacial lakes and glacial moraine records. By analysing proxies as chironomids, alkenones, macro fossils and DNA temperatures can be reconstructed. Proglacial lake sediments and glacial moraine records help to reconstruct former ELA of glaciers and can be used to reconstruct precipitation records in combination with available temperature records.

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.

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]

Aerosol sampling by a High-Volume Sampler (TECORA eco-highvol equipped with digital PM1 sampling inlet, nominal flow 500 lpm) for the collection of ambient aerosol particles with aerodynamic diameter < 1 μm (PM1) on pre-washed and pre-baked quartz-fiber filters (PALL, Ø= 18cm). Sampling time: 3-4 days per sample. A multi-technique analytical approach for the characterization of the sampled organic aerosol: Organic matter (OM) and Organic Nitrogen (ON). Analytical techniques employed are based on nuclear magnetic resonance spectroscopy (NMR) and Aerosol Mass Spectrometry (HR-TOF-AMS applied off-line) for the OM characterization, C and N elemental analysis (CN-EA) and ion chromatography (IC) for inorganic ions and alkyl-amines. -NMR functional groups (Aromatics, anomeric/vynilic, H-C-O, H-C-C=, H.C) -NMR tracers: Levoglucosan, Methane-sulphonic acid (MSA), Hydroxymethane-sulphonic acid (HMSA), Amines (mono-, di- and tri-methyl amines, etc.) -HR-TOF-AMS (off-line): main species (Org, SO4, NO3, NH4, Chl), elemental ratios (OM:OC, O:C, H:C) & tracer fragments (m/z43, 44, 60 etc.) -NMR & AMS OA source apportionment
