ISotopic and physical-chemical MOnitoring of GLACial drainages and sea water in the Ny-Ålesund area (Svalbard) The project concerns an isotopic and physical-chemical monitoring of inland glacial drainages and ocean water into Kongsfjorden. It is aimed at defining the dynamic processes of the glacial melting and evaluating the consequent transfers of fresh water towards the Arctic Ocean. The dataset includes the continuous measurements (1 data/15 min) performed during summer season by a CTD diver. Parameter: Temperature, electical conductivity, water level.

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

Climate-Cryosphere-Carbon interactions in Kongsfjorden, Svalbard (C3) Use sediment cores as archives of climate-induced destabilizations in the fjord. By targeting well known past climate changes (MWP and LIA) we will understand how the C3 system varied during natural warming and cooling events. Retrieve of two sediment cores in Kongsfjorden, in summer 2017, to encompass the last 1k years.

Measurements are obtained using a Pyrgeometer Kipp&Zonen, model CGR4, installed at Thule Air Base (220 m a.s.l.) in May 2013. The instrument sensitivity was determined during factory calibration for temperatures down to -40 °C, thus specifically suited for the polar environment. Data are acquired by a datalogger at 30 s time intervals and then transferred to a PC. The CGR4 and its dedicated PC are maintained by Daniela Meloni at ENEA.

RIS: 11079 ARctic DISsolved CO2 (AR-DIS-CO2) Project start: 2018-08-16 end: 2023-08-16 The project tackles the dynamics of dissolved gases in the ocean water of the Kongsfjorden (Svalbard islands, W archipelago). The main goals are: the characterization and monitoring of Kongfjorden’s waters in terms of dissolved gases species and ii) the identification and understanding of the relationships between dissolved gases time-variations and glaciers melting dynamics. Focus of the research activities is to monitor and comprehend the processes involving major dissolved gas species, trying to identify and understand how drainage melt glaciers influence the TDIC and gas contents of the fjord. The project is also aimed to develop a portable instrument for on-site measurements of TDIC and dissolved gases (in particular CO2, but also O2, N2, Ar, CH4, H2). Vertical profiles of temperature, pH, salinity along selected site in the Kongsfjorden. The selection of measurement sites was addressed to obtain data at least from one of the most deep vertical profile and also from profiles close to main glaciers drainages (Bayelva basin and Kronebreen-Kongsvegen glaciers). TDIC measurements is performed in water samples. water samples in glass bottles pre-evacuated are collected for gases determination.
