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.

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.

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.

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.

Timeseries recorded at the mooring S1, at nominal depth of 1000 m during different deployments. The scope of the measurements is to study the temporal variability of the thermohaline properties of the Norvegian Deep Water, and assosiated deep flow
