Snow water equivalent at the Gruvebadet Snow Resarch Site

Chronobiology of polar organisms (Chronopolar) Monitoring water parameters in surface and deep (3.0 meters) using DS18B20 + rasberry-pi. Sample collection: Lepidurus arcticus.

This dataset comprises measurements from a moored single-point acoustic current meter, collected by the Mooring Dirigibile Italia (MDI), which is managed by the Institute of Polar Sciences of the National Research Council (CNR). The data was gathered at Kongsfjorden, Svalbard Island, since 10 September 2010. This dataset is also part of the SIOS-Svalbard Integrated Arctic Earth Observing System, developed to observe the impacts of climate change, including the rapid loss of sea ice cover, the retreat of local glaciers, and the Atlantification of Arctic seas. Measured properties are: subsurface temperature and subsurface currents. The acquisition of this time series data is still ongoing and will continue, bolstered by the inclusion of this infrastructure within the framework of the Italian PNRR project ITINERIS. This ensures sustained data collection and further enhances our understanding of the observed environmental changes.

Terrestrial Photography ApplicationS on Snow covEr in Svalbard (PASSES) Project start: 2018-04-15 - end: 2021-12-31 The purpose of this activity is the development of a new snow product focused on the estimation of the fraction of snow cover in selected sites at different spatial resolutions. This dataset will be aimed to support the estimation of cryospheric information using remotely sensed data, with a particular attention to data obtained in the framework of the Copernicus program. The availability of this dataset in a natural laboratory such as Svalbard islands will support the reduction of the gap between remotely sensed data and modeling activities. This added value will be very important considering the higher spatial resolution of the sensors recently deployed. The dataset will be based on re-using data obtained from public repositories such as the digital elevation model of Svalbard, the available webcam imageries in Svalbard and satellite products from Landsat, Sentinel and MODIS missions. All the available data will be integrated in order to estimate the fraction of snow cover, at different spatial resolutions, for each satellite mission. These estimations, computed at different sites in Svalbard islands, will offer the opportunity to better integrate results obtained by remote sensing with modeling and air-snow interactions studies. Particular attention will be devoted to the formalization of agreements with raw-data providers in case of not-public licensing policies.

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.

ISotopic and physical-chemical MOnitoring of GLACial drainages and sea water in the Ny-Ålesund area (Svalbard) (ISMOGLAC) Sampling and in-situ measurements on snow and water, performed into both Kongsfjorden and glacial streams that originate in supraglacial, englacial and subglacial zones of different glaciers (Midtre Lovenbreen, Austre broggerbreen, Vestre Broggerbreen, Kongsvegen). Dataset concerns water isotopes signature of snow and Kongsfjorden water and physical-chemical data of the latter.

The automated nivological station was installed in November 2020 in a flat area over the tundra about 80 meters far from the Gruvebadet Atmospheric Laboratory and nearby a snow sampling site from where weekly snow samples are collected for chemical analysis. Sensors have been calibrated by their companies before installation and are connected to a datalogger for continuous acquisition. For all the parameters, data are logged with 10-minute time resolution and then averaged over 1 hour. This activity is carried out by the Aldo Pontremoli Centre part of the Joint Research Agreement ENI-CNR.

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.

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.
