ISotopic and physical-chemical MOnitoring of GLACial drainages and sea water in the Ny-Ålesund area (Svalbard) The dataset includes vertical profiles of physical-chemical performed on-site in different sites along the fjord in Kongsfjorden.

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.

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

Atmospheric Gondola for Aerosol Profiles (AGAP) The scientific goals of AGAP are to develop novel aerosol payloads and evaluate the vertical distribution of aerosol properties in the Arctic Boundary Layer. Dataset consists in Aerosol vertical profiles gridded at a 50 m spatial resolution: R, T, P, RH, Aerosol size distribution, BC concentration, O3. Maximum altitudes 1500 m.

Arctic Present Climate Change and Past Extreme Events (ARCA) The data refer to rock magnetic and paleomagnetic measurements taken at a 1-cm spacing on u-channel samples collected from piston cores from the continental platform and slope of the NW Barents Sea. Measurements were carried out in the paleomagnetic laboratory of INGV in Rome, using a superconducting rock magnetometer installed in a magnetically shielded room.

The column water vapor or Precipitable Water Vapor (PWV) is measured at Thule Air Base (76.5°N, 68.8°W), Greenland, by means of a ground-based millimeter-wave spectrometer (GBMS) installed at 220 m a.s.l. The GBMS observes rotational lines of atmospheric molecules emitting between 230 and 280 GHz, with a spectral pass band of 600 MHz. The PWV is calculated from direct measurements of atmospheric opacity (tau) at the indicated frequencies by using the linear relation PWV = a+tau*b, where a and b depend only on frequency. Measurements have a temporal resolution of 15 minutes and are carried out continuously when the GBMS is operated.

This proposal will focus 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
