Arctic Century Expedition – One month in the Russian Arctic on board the research icebreaker Akademik Tryoshnikov

An international team of scientists has spent a month on board the Russian research icebreaker, the Akademik Tryoshnikov, studying climate change impacts in the Arctic. From the atmosphere to the High Arctic islands, down the water column to the depths of the ocean, researchers are investigating the ecosystems and biodiversity of the region, and the role they play in our global cycles. Physical and chemical measurements of the atmosphere and the ocean seek to document their interactions with sea ice and to improve forecasts of the changing Arctic environment.

High-resolution ice and sediment cores, that we collect, will allow us understand the history of the ice caps, past climate variability and better understand our future. From the distant past to the present day, litter found at sea and on the beaches of these remote islands paints a picture of the current impact we have on our planet.

This multidisciplinary expedition to the Kara and Laptev Seas, including the archipelagos of Franz Josef Land and Severnaya Zemlya, marks the celebration of one hundred years of the Russian Arctic and Antarctic Research Institute.

The Arctic Century Expedition brought together 29 scientists and 30 early career researchers from 13 countries, to bring new light to these internationally rarely-visited hotspots for climate studies in the Arctic. The expedition was organized jointly by the Arctic and Antarctic Research Institute in St. Petersburg, the Swiss Polar Institute and the GEOMAR Helmholtz Centre for Ocean Research Kiel in Germany.

Open position: Project Manager for Synoptic Arctic Survey

At the Geophysical institute we have an open permanent position as Project Manager (Advisor) for the international secretariat of the Synoptic Arctic Survey, hosted by Norway and the UiB. The position is jointly funded by strategic allocations from the UiB and by the EU H2020 project ArcticPassion. The initial scope of the position may change with time, depending on future funding.

The CASSANDRA Oceanographic Cruise is imminent

The CASSANDRA (AdvanCing knowledge on the present Arctic Ocean by chemical-phySical, biogeochemical and biological obServAtioNs to predict the futuRe chAnges) project was recently approved as part of the Italian Arctic Research Program (PRA), and an Arctic oceanographic cruise is planned on board the R/V “Laura Bassi” (Figure 1).

The CASSANDRA oceanographic cruise will have 15 researchers on board and will depart from Longyearbyen (Svalbard Islands) on 29 August and arrive in Bergen (Norway) on 14 September 2021. The project is coordinated by the Italian Institute of Polar Sciences (ISP) and involves the National Institute of Oceanography and Applied Geophysics (INOGS) as a participant.

CASSANDRA project seeks to quantify the present state of the physical, chemical, biological and biogeochemical systems of a sub-Arctic historic transect at 75°N crossing the Greenland Sea Gyre (Figure 2). As part of the Synoptic Arctic Survey (SAS), CASSANDRA will operate with a multidisciplinary approach, making use of common protocols.

Emphasis of the project will be also devoted to understanding the major ongoing transformations on the water masses, the marine ecosystem and the carbon cycle. Other relevant measurements along the route of the vessel without interference with navigation will be made: upper layer currents by hull mounted ADCP, surface temperature and salinity by thermosalinograph, broadband shortwave and longwave radiation fluxes, automatic observation of cloudiness conditions, meteo parameters, and sampling activities of biological aerosol.

CASSANDRA will train young researchers and create opportunities to promote the next generation of polar researchers. We chose the name CASSANDRA because today the environmental message manages to permeate more and more, both in the social strata of the population and at the political level, and we would like to dispel your legend of unheard Prophetess.
