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).

Climate-Cryosphere-Carbon interactions in Kongsfjorden, Svalbard (C3) Use sediment cores as archives of climate-induced destabilizations in the fjord. By targeting well known past climate changes (MWP and LIA) we will understand how the C3 system varied during natural warming and cooling events. Retrieve of two sediment cores in Kongsfjorden, in summer 2017, to encompass the last 1k years.

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).

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) 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.

Marine Arctic fish diversity and habitat ecology (Aristotle) Aims at improving current knowledge on the fish fauna in the Kongsfjorden. Two complimentary approaches are applied: i) genetic analysis at chromosomal level; ii) use of non-invasive video technologies to study fish communities. List of fish species and pertaining biologic information (size, weight, sex).

Atmospheric Gondola for Aerosol Profiles (AGAP) Developing novel aerosol payloads and evaluate the vertical distribution of aerosol properties in the Arctic Boundary Layer. Aerosol vertical profiles by tethered balloon: Aerosol vertical profiles gridded at a 50 m spatial resolution: R, T, P, RH, Aerosol size distribution, BC concentration, O3. Maximum altitudes 1500 m.

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.

Homogenized Tethered Balloon record at station Ny-Ålesund, Spitsbergen in 2018 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 by tethered balloon: Aerosol vertical profiles gridded at a 50 m spatial resolution: R, T, P, RH, Aerosol size distribution, BC concentration. Maximum altitudes 1500 m.
