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

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.

Observing earth critical zone processes in the bayelva basin (CZO@Bayelva) The dataset includes CO2 fluxes measurements during summer period in different area along the transect from CCT to Ny-Alesund airport. The measures are performed using a portable accumulation chamber in dark (Ecosystem respiration, ER) and light (Net Ecosystem Exchange) condition. For each plot, about 20 measures are performed, including soil temperature and volumetric soil water content. CO2/H2O daily average values and standard deviation. Each measurement day contains a number of half-hour measurements.

Arctic Present Climate Change and Past Extreme Events (ARCA) Tephra are volcanic particles that can be used as chrono-stratigraphic tool for correlating sedimentary archives once they have been identified. Marine sediments have been analyzed from the GS191-01 PC core recovered during the PREPARED CRUISE 2014 in the Arctic Sea (western of Svalbard Islands). Some of these samples resulted positive and geochemical analyses will be perfomed to determine the volcanic source and establish possible correlations with known eruptions.

Cyclone Sample collection Teams collect two weekly 24-hour samples Teams create metadata by scanning QR codes on cyclone sampler and sample vial with Lifeplan app Teams store samples until shipment in a freezer - Sample shipping to Sweden - Sample cleaning by Lifeplan - Sample shipping to Guelph - Sample sequencing - Transfer of sequencing data to Lifeplan - Bioinformatics - Species lists Through LIFEPLAN, we aim to establish the current state of biodiversity across the globe, and to use our insights for generating accurate predictions of its future state under future scenarios. In LIFEPLAN, we thus characterize biological diversity through a worldwide sampling program, and develop the bioinformatic and statistical approaches needed to make the most out of these data.

Carbon flux and its isotopic signature in arctic regions under climate change (CarIsoA) Study carbon flux by evaluating CO2 assimilation on target species. Parameters: Light curve, CO2 curve and temperature curve for on Salix polaris, Saxifraga cespitosa, Dryas octopetala and Carex polaris

The aim of this project is to detect the presence of NIMS and door knocker species in marine coastal waters of Svalbard by using a traditional fishing system (traps) and complementary multi-approach monitoring techniques (underwater cameras, hydrophones, plankton net and eDNA collectors) to find all elusive or cryptic species and those present at low density.

Observing Earth critical zone processes in the Bayelva basin (CZO@Bayelva). Data represents the average values and the corresponding standard deviation of Net Ecosystem Exchange (NEE), Ecosystem Respiration (ER) and Gross Primary Productivity (GPP) obtained from two different sites in the tundra of the Bayelva river basin: One site (named CZ) is located in the vicinity of the Climate Change Tower. The other one (named "Airport") is in the vicinity of the Ny Alesund Airport. Each average value is obtained as a mean over a set of around 20 point measures for each plot and each sampling date. Flux data are complemented by measurements of soil temperature, soil volumetric water content, air temperature and relative humidity, and solar irradiance. CO2 fluxes are measured using a flux chamber and a LI-COR IRGA by means of the Dynamic Flux Chamber method.

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).

Arctic Present Climate Change and Past Extreme Events (ARCA) CD4 core was micromilled at 200 μm increments using a micro-milling method (Drysdale et al., 2012). The stable isotope composition of the powders was measured on CO2 gas released by reaction with 105% H3PO4 at 70°C, which was measured using a mass spectrometer. Isotopic results are reported using the conventional δ-notation in per mille (‰), with reference to the Vienna Pee Dee Belemnite (V -PDB) standard. Instrument : MC-ICPMS, Nu-Instruments Plasma, Finnigan GasBench Parameter : Th**230/U**238 and U**234/U**238 activity ratios, (δ**13)C and (δ**18)O
