Sediment core subsampling

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.

RAD7 Radon Detector

RAD7 Radon Detector

RAD7 Radon Detector

RAD7 Radon Detector – Real-time Continuous Radon Monitor with Spectral Analysis – is our new purchase. This equipment will be used for  222Rn measurements to trace submarine groundwater discharge. RAD7 was financed by the Norwegian Financial Mechanism 2014–2021 (85%) and national co-financing (15%) within Basic Research Programme. The RAD7’s technology (electrostatic precipitation followed by high-resolution alpha spectrometry) is the only one that gives clear separation between the various radon progeny species (‘species idenfitication’). That allows the instrument to completely reject the counts from the lead-210 background, and also make a simultaneous, independent measurement of radon and thoron by summing counts in each of four energy windows. The DURRIDGE RAD7 technology was invented by Lee Grodzins and his PhD student Stephen Shefsky at MIT in the early 90s, and commercialised as the RAD7. Fot. Durridge https://durridge.com/

Study area (Arex’21)

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
