Abstract:
Abstract. Ice algae play a fundamental role in shaping
sea-ice-associated ecosystems and biogeochemistry. This role can be
investigated by field observations; however the influence of ice algae at
the regional and global scales remains unclear due to limited spatial and
temporal coverage of observations and because ice algae are typically not
included in current Earth system models. To address this knowledge gap, we
introduce a new model intercomparison project (MIP), referred to here as the
Ice Algae Model Intercomparison Project phase 2 (IAMIP2). IAMIP2 is built
upon the experience from its previous phase and expands its scope to global
coverage (both Arctic and Antarctic) and centennial timescales (spanning the
mid-20th century to the end of the 21st century). Participating
models are three-dimensional regional and global coupled sea-ice–ocean
models that incorporate sea-ice ecosystem components. These models are
driven by the same initial conditions and atmospheric forcing datasets by
incorporating and expanding the protocols of the Ocean Model Intercomparison
Project, an endorsed MIP of the Coupled Model Intercomparison Project phase 6 (CMIP6). Doing so provides more robust estimates of model bias and
uncertainty and consequently advances the science of polar marine
ecosystems and biogeochemistry. A diagnostic protocol is designed to enhance
the reusability of the model data products of IAMIP2. Lastly, the
limitations and strengths of IAMIP2 are discussed in the context of
prospective research outcomes.
