On Tuesday the 4th July at 14:00 (2PM), the Greenfjord Team will conduct a test flight of their weather balloon on the hill behind the resarch station. They will also present the research and work they are doing in Narsaq. Angutimmarik will be present to translate into Kallalisut/Greenlandic. Everybody is welcome: kids,parents and curious people.

Summary

Accelerated climate change in the Arctic imposes profound impacts on Greenlandic fjord systems. These are fragile because of the delicate nexus between the cryosphere, ocean, land, atmosphere and biosphere. Moreover, these emblematic Greenlandic landscapes are at the heart of socio-economic and cultural systems of local livelihood. Warming induces glacial melt and calving leading to enhanced freshwater fluxes. The modified fluxes impact marine ecosystem dynamics and nutrient circulation, which in turn affect the marine food-web with cascading effects: At low trophic levels, changing phytoplankton blooms impact atmospheric chemistry and cloud formation, and hence the surface radiation budget. At high trophic levels, fish are affected with important implications for local livelihood and economy, which largely depend on marine resources.

With GreenFjord, we aim to create process understanding of how climate change affects fjord ecosystems, and how this propagates to biodiversity and livelihoods. The ultimate goal is to translate the new understanding into models to simulate and predict the evolution of future fjord systems, including glacier mass loss, trophic evolution and carbon cycling. Our field work will be conducted on land in the ocean (RV Sanna), and entail deep engagement of local residents. Key activities include:

Cryosphere: glacier calving and impact on fjord water and nutrient circulation

Ocean: physical and microbial characteristics of fjord systems

Biosphere: determination of biodiversity by means of environmental DNA

Atmosphere: influence of local natural emissions on cloud formation

Land: export of terrestrial organic matter to the ocean

Human: understanding the relationship between local livelihoods and fjord socio-ecosystems
