Biogeochemical Exchange Processes at Sea Ice Interfaces (BEPSII) is an international expert group on sea-ice biogeochemistry focusing on harmonizing methodologies for sea-ice biogeochemical research and observation; sea ice biogeochemical data-archiving approaches and data mining; process studies to determine impacts of physical sea-ice processes on ecology and biogeochemical cycles; improvement of the representation and evaluation of sea ice biogeochemistry in regional and Earth system numerical models; synthesis and integration of observational and modeling efforts including conceptual model development to describe sea ice interactions in or with the Earth system. More recently BEPSII is also focusing on big-picture questions of global relevance and feedbacks related to the sea ice ecosystem.

BEPSII was initiated through a Scientific Committee of Ocean Research (SCOR) Working Group (SCOR WG 140, 2012-2016) and triggered a more specific methodology focused working group on Measuring Essential Climate Variables in Sea Ice (ECV-Ice, SCOR WG 152) in 2017. Since the end of SCOR WG 140, BEPSII has been endorsed by three major international research organizations: Surface Ocean Lower Atmosphere Study (SOLAS, 2015), Climate and Cryosphere (CliC, 2015) and Scientific Committee of Antarctic Research (SCAR, 2016). For this special feature we welcome all contributions related to biogeochemical processes related to sea ice and its interfaces with the atmosphere and ocean as well as physical processes which may have feedback on the biogeochemistry. We also welcome studies assessing how climate change may impact these processes and the sea-ice ecosystem as a whole.
