Freshwater input in the Kongsfjorden (FIKO) Project Start: 2010-06-01 End:2020-12-31 FIKO project aims to acquire measurements of the chemical and physical characteristics of water masses in Kongsfjorden, and estimate the amount of fresh water released from glaciers, in order to study the interactions of this water with the warmer Atlantic waters. The dataset consist of water column profiles of pressure, temperature, salinity, fluorescence and turbidity located within the Kongsfjorden at Platform: MS Teisten - Kings Bay AS, vertical resolution 0.5 m Kongsfjorden_CTD_profiles_2013: 48 water column profiles by SBE19plus CTD probe Kongsfjorden_CTD_profiles_2014: 42 water column profiles by SBE19plus CTD probe Kongsfjorden_CTD_profiles_2015: 82 water column profiles by SBE19plus CTD probe Kongsfjorden_CTD_profiles_2016: 34 water column profiles by SBE19plus CTD probe Kongsfjorden_CTD_profiles_2017: 5 water column profiles by SAIV A/S SD204 – CTD/STD Kongsfjorden_CTD_profiles_2018: 41 water column profiles by SAIV A/S SD204 – CTD/STD Kongsfjorden_CTD_profiles_2019: 12 water column profiles by SAIV A/S SD204 – CTD/STD Kongsfjorden_Krossfjorden_CTD_profiles_2020: 29 water column profiles by SBE19plus CTD probe in 3 different areas: Krossfjorden, kongsfjorden at one transect along the fjord axis, off Bayelva river area.

The dataset consist of 82 water column profiles of pressure, temperature, salinity, fluorescence and turbidity mostly located on one the main transect along the fjord axis. The transect has been repeated 4 times.

Spatial variability: validation dataset on pops concentrations in snow (SVAL-POPS) We aim to measure the spatial variability of chosen persistent organic pollutants levels in the snow. The samples will represent three spatial scales: 2-5 m spacing, 0.5-1 km distance, and two sites across Svalbard: Ny Ålesund and Hornsund. These will be compared thanks to a laboratory crosscheck.

The dataset consist of 5 water column profiles of pressure, temperature, salinity, fluorescence and turbidity. at Platform: MS Teisten - Kings Bay AS .

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.

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).

The Italian project CASSANDRA is part of the international framework of the Synoptic Arctic Survey which seeks to collect oceanographic data in the Arctic Ocean in the two-year period 2020-2021 involving the coordination of many research vessels belonging to different nations. The aim is to determine the current state and major ongoing changes in the Arctic marine system by generating an oceanographic dataset that allows for a comprehensive characterization of Arctic hydrography and circulation, carbon uptake and ocean acidification, the distribution of possible pollutants, the functioning and productivity of organisms and ecosystems.
