Special Feature: Biogeochemical Exchange Processes at Sea-Ice Interfaces (BEPSII)
Assessing biogeochemical and physical processes at the ocean-ice-snow-atmosphere interfaces and their role in the climate system
Current models are inadequate to represent and quantify biogeochemical processes in sea ice areas and hence to estimate impacts on the regional and global climate. The SCOR WG BEPSII aims at identifying the feedbacks between biogeochemical and physical processes at the ocean-ice-snow-atmosphere interfaces and within the sea-ice matrix and their role on various scales (from micro to global). This Special Feature summarizes methods for observing sea-ice biogeochmistry, provides guidelines for productive collaboration between modellers and observationalists, reviews the status and gaps of major biogeochemical processes, and summarizes results from modelling studies.
