Brief narrative summary of the content of the resource(s)

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.

The Climate Change Tower Integrated Project (CCT-IP) reflects the priorities of Italian Arctic research and aims to investigate the interactions among all components of the Arctic climate system. The Amundsen-Nobile Climate Change Tower (CCT) serves as the project’s central infrastructure, providing continuous measurements of atmospheric parameters at multiple heights and at the critical interface between the surface and the atmosphere. A SPN1 net radiometer, installed at a height of 33 m in 2023, is used to measure the radiation partition between incoming direct and diffuse irradiance. Previously, in 2009, a combination of sensors—including a CNR1 net radiometer at 33 m and CM11 and CG4 sensors at 25 m—was deployed for the same purpose. Radiation data are processed to provide 30-minute averages (μ) and standard deviations (σ), along with derived products such as total net radiation and an indication of sun presence. These data will be available for download. Additionally, 1-minute resolution data are available for download upon request.

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

Isotopic characterisation of arcic ponds Sampling of ponds and surrouding terrestrial envionrment. matter (expressed as ash fry dry matter) and N content as a percentage in soil and lake sediment.

Holocene environmental change on Svalbard (HOLS) The aim of this international umbrella project is to study the variation of environment and climate in Svalbard during the Holocene. At the moment no integrated temperature or precipitation record exists for the entire Holocene on Svalbard. We aim to reconstruct temperature and precipitation for the Holocene by using a combination of lake sediment records, proglacial lakes and glacial moraine records. By analysing proxies as chironomids, alkenones, macro fossils and DNA temperatures can be reconstructed. Proglacial lake sediments and glacial moraine records help to reconstruct former ELA of glaciers and can be used to reconstruct precipitation records in combination with available temperature records.

EEE@NYALESUND (EEENYA) The Dataset contains flux of cosmic rays measured at different locations at Ny Alesund. Each cosmic ray event will be tagged in time using GPS. Cosmic rays data will be correlated with atmoshperic conditions, also contained in the dataset. Measurement site: Ny Alesund: 1. Dirigibile Italia Station, 2. Gruvbadet laboratory, 3. close to the Amundsen-Nobile tower

Ionospheric Scintillations Arctic Campaign Coordinated Observations (ISACCO) the project aims the monitoring of Total Electron Content and scintillations by suitably modified GNSS receivers sampling at 50 Hz for ionospheric modelling in NyAlesund

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.
