Sediment core subsampling was done by PhD student Reza Saghravani, Principal Investigator of ArcticSGD project Dr. Beata Szymczycha and Dr. Eng. Magdalena Diak. Core were cut every 10 cm. Dr. Aleksandra Winogradow centrifuges the sediment to extract pore water from cores for further analysis. Special thanks to Prof. Zajaczkowski and his team in Paleoceanography Department. Fot.

The study areas were located in the Kongsfjord – Krossfjord, Isfjorden and Norwegian Fjords. Our research contribute to fulfill existing gaps in the knowledge in the Arctic hydrology. We have tremendous problem due lack of enough information about the at least basic water cycle mechanism, budget and discharge. Moreover, the ongoing climatic changes are visible to the naked eye and have significant impact on these processes. We can compare photos observed during Arex’21 cruise and photo of Kongsfjord taken by S. Gerland from publication Svendsen et al. 2002 (Svendsen, Harald, et al. “The physical environment of Kongsfjorden–Krossfjorden, an Arctic fjord system in Svalbard.” Polar research 21.1 (2002): 133-166.). We would like to kindly invite you to watch videos and photos taken and prepared by PhD student Reza Saghravani
Measurements of DIC and Total Alkalinity samples, which were collected during AREX’21 in Spitsbergen (Svalbard) are carried out. DIC samples are analyzed using DIC analyzer (ApolloSciTech ™) and Trace Gas Analyzer (LI-COR ™) and Total alkalinity using Dosimat plus (Metrohm ™). Fot. Reza Saghravani
During our AREX’21 cruise in Arctic we collected also pore water for different parameters DIC, DOC, total alkalinity, metals, nutrients and chloride. Samples were also collected on the land expeditions by push-point lance. Obtained results for pore water profiles can deliver information about fluid transport in sediments. Fot. Reza Saghravani
During our AREX’21 cruise in the Arctic we collected water samples from the required depths in a water column for different parameters like DIC, DOC, total alkalinity, metals, nutrients, water isotopes and chloride. We observed interesting chemical profile. Fot. Reza Saghravani
Furthermore, we collected additional samples directly from ponds and springs. Based on the literature data, it has been revealed that springs and pingos can serve as discharge points for subpermafrost groundwater in the Arctic. Literature data showed that pingo springs enable methane that has accumulated underneath the permafrost to escape directly to the atmosphere, our limited understanding of the groundwater system brings significant uncertainty to the understanding of how methane emissions will respond to changing (Hornum_2021 https://doi.org/10.5194/tc-14-4627-2020).
