Seasonal sea ice – a new source of bromine during polar night

Research project
Active research
Project period
2019 - 2020
Project owner
Department of Marine Sciences

Short description

The major objective is to determine the emission of marine naturally produced trace gases, so called volatile halogenated organic compounds or halocarbons, to the atmosphere.

The aim is to examine the physical and biogeochemical sea-ice-air fluxes during sea-ice growth and their impacts on Arctic tropospheric chemistry during the Arctic winter, through the participation in the international MOSAIC experiment (multidisciplinary drifting Observatory for the study of Arctic climate) with R/V Polarstern 2019-2020. The investigations include the role of seasonal sea ice as a reaction surface for chemical conversion processes, and as a source or sink for halocarbons.
