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.

Measurement of the concentration and turbulent flux of CO2 and CH4 at 15 m above sea level on the CCT.

Data collected by the WINTER-CZ Monitoring Station. The CO2 and the temperature is sampled is measured inside the soil, the snowpack (when the station is covered by the snow) and the atmosphere. Other variables are collected as well: the humidity and the oxygen content of the soil, the snowpack height, the humidity and the temperature of the air, the wind speed and direction.
