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.

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]

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.

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 Brøgger peninsula located in the north-western sector of Svalbard, is rich in shallow lakes, very different in morphology, height from sea level, composition of lake sediments, seasonal snow cover and presence/absence of migratory avian fauna in their catchment areas . In 2022, as part of the EcoClimate project (PI Prof. Edoardo Calizza), the research unit of the Institute of Polar Sciences of Messina set up a first series of sensors (Temperature; light) in 8 lakes spatially distributed at different heights from the sea and with different inputs of organic and inorganic substance. The observatory is currently in its second year of measurements.

The dataset includes fourteen seawater surface sampling points taken with Niskin bottles on board the MS-Teisten (Kings Bay)
