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.

Arctic Present Climate Change and Past Extreme Events (ARCA) Analysis of RES datasets available. Production of thematic maps of representative ice-calving effect in some Greenland outlet glaciers. Development and upgrade of INGV RES system.

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.

Sulphate contributions to PM10 aerosol sampled at Gruvebadet Observatory (Ny-Ålesund)

Sampling of PM10 aerosol using a cascade impactor to define the chemical composition in six different size stages. The quartz filters were extracted with ultrapure water and water soluble species were determined: major ions, MSA, carboxylic acids, amino acids, sugars, phenolic compounds, and other organic water-soluble emergening pollutants.

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

Atlantification of Arctic ocean is causing a sharp increase in temperature and salinity around Svalbard Islands and in Kongsfjorden. Such phenomenon and the input of sediment-rich glacial meltwater influence salinity, water column turbidity, and light penetration with ecological implications on the microbial features.

The AUXMON (AUXiliary MONitoring) project aims at providing a continuous monitoring of auxiliary variables useful to support investigation of Arctic atmospheric composition, temperature, humidity. A small network of 4 AIRQino station is the core infrastructure of the project. Three of these stations are positioned outdoors, one (station id 266) is placed inside the italian base. Specifically, the AIRQino stations are low-cost sensors providing information about the concentration of CO2, gaseous pollutants, particulate matter, air temperature and relative humidity.

Continuous Vis-Near IR Characterization of snow-ice surface in Ny-Ålesund (SnowIceCReM) The activity foreseen for 2015-2020 includes: continuous full-range reflectance measurements; continuous multispectral observations; ground-truth survey on snow surfaces. The first part of the activity is attempted to replicate the experiment carried out in 2014 where a VNIR spectroradiometer were deployed at the CCT. Hardware upgrades will be coupled with the addition of some position and optical reference targets. An hemispheric webcam will acquire high resolution sky and ground images to support the experiment in terms of cloud and snow cover/roughness characterization, and to provide a quality check of the rotating support position by means of the above mentioned specific targets. The availability of such accessory information will help on selecting a homogeneous spectral albedo dataset. The same quality check approach will be used also for the deployment of a second instrument that will be developed in order to obtain fixed band albedo at 860, 1240 and 1640 nm. Both measurements will be hemispheric, in the 350-2500nm wavelength range. While the first set up obtains asynchronous spectral albedo, the second one provides synchronous spectral albedo on bands selected considering sensors deployed on satellites. The final task will be persecuted with a ground-truth survey focused on calibrating the two different hemispherical receivers with bidirectional observations.
