Main a trace chemical markers annually and seasonally averaged concentrations in the aerosol (bulk and PM10) sampled in 10 sites in the Arctic and Panarctic regions

Aerosol scattering coefficient at 1 wavelength (530 nm) measured using a nephelometer M903 manufactured by Radiance Research and absorption coefficient at 7 wavelengths (370, 470, 520, 590, 660, 880, 950 nm) measured using an AETHALOMETER AE33 from Aerosol Magee Scientific.

Daily averages of equivalent black carbon from aerosol absorption coefficient at 660nm measured using a Particle Soot Absorption Photometer (PSAP), manufactured by Radiance Research. MAC equal to 10 m^2/g.

This dataset comprises measurements from moored Acustic Doppler Current Profiler (ADCP), collected by the S1 Mooring, which is managed by the Institute of Polar Sciences of the National Research Council (CNR) and National Institute of Oceanography and Applied Geophysics (OGS). The data was gathered on the Fram Strait south of the Spitsbergen in an open-sea area strongly influenced by both the interaction between Atlantic (northward-moving) and Arctic (southward-moving) waters as well as by the presence and winter formation of sea ice and atmospheric forcing. The oceanographic S1 Mooring was anchored at about 1040 meters depth, since June 2014 and is 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. The ADCP mounted at different depths (782, 740 and 488 m depth) between the 2019 and 2023 measures the sea-water currents intensity and direction along the water column.

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]

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 Climate Change Tower Integrated Project (CCT-IP) represents the guide lines of the italian research in the arctic and aims to study the interaction between all the components of the climate system in the Arctic. The Amundsen-Nobile Climate Change Tower (CCT) is the key infrastructure of the project, and provides continuous acquisition of the atmospheric parameters at different heights as well as at the interface between the surface and the atmosphere. Precipitation data (liquid and solid) are obtained from an optical disdrometer (Vaisala FD70). Partly funded by Arctic PASSION project (agreement number 101003472). Data are available under request.

Aerosol Optical Depth (AOD) measured by the NOrwegian Institute for Air Research (NILU) at Ny-Alesund between 2002 and 2010 by using a Precision Filter Radiometer (PFR). AOD is provided at 500 nm and alpha in the spectral range (nm) 411.9-862.5.
