Sampling of PM10 aerosol using a cascade impactor to define the chemical composition in six different size stages. The quartz filters were extracted with ultrapure water and water soluble species were determined: major ions, MSA, carboxylic acids, amino acids, sugars, phenolic compounds, and other organic water-soluble emergening pollutants.

Permafrost Release Into The Marine System In A Warming Arctic (PRIMA) Data about Physical and chemical oceanography and vertical fluxes of sedimentary material from Mooring Aldo Pontremoli (MAP) and geochemical biomarker data from sediment core.

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.

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

Continuous Vis-Near IR Characterization of snow-ice surface in Ny-Ålesund (SnowIceCReM) The activity foreseen for 2015-2020 includes: continuous full-range reflectance measurements; continuous multispectral observations; ground-truth survey on snow surfaces. The first part of the activity is attempted to replicate the experiment carried out in 2014 where a VNIR spectroradiometer were deployed at the CCT. Hardware upgrades will be coupled with the addition of some position and optical reference targets. An hemispheric webcam will acquire high resolution sky and ground images to support the experiment in terms of cloud and snow cover/roughness characterization, and to provide a quality check of the rotating support position by means of the above mentioned specific targets. The availability of such accessory information will help on selecting a homogeneous spectral albedo dataset. The same quality check approach will be used also for the deployment of a second instrument that will be developed in order to obtain fixed band albedo at 860, 1240 and 1640 nm. Both measurements will be hemispheric, in the 350-2500nm wavelength range. While the first set up obtains asynchronous spectral albedo, the second one provides synchronous spectral albedo on bands selected considering sensors deployed on satellites. The final task will be persecuted with a ground-truth survey focused on calibrating the two different hemispherical receivers with bidirectional observations.

The AUXMON (AUXiliary MONitoring) project aims at providing a continuous monitoring of auxiliary variables useful to support investigation of night-sky brightness. Sky-Quality Meters (SQM) sensors are one of the core infrastructure of the project. They are low-cost sensors for measuring night sky brightness.

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.

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).
