SCOR WG 140 on
Biogeochemical Exchange Processes at the Sea-Ice Interfaces (BEPSII)
Chair: Jaqueline Stefels (Netherlands)
Co-chair: Nadja Steiner (Canada)
Local member host: Klaus Meiners (Australia)
2014 Annual meeting in Hobart
The 2014 annual meeting will be following the International Symposium on Sea Ice in a Changing Environment. The meeting will contain a short report by task group leaders as well as a series of presentations and discussions of individual project results and status. In addition to the full day meeting on Sunday, individual task group meetings will be scheduled through the week.
Date: Sunday March 16 – 9 am to 5pm
Location: IMAS Waterfront building, flex room, ground floor
Schedule: The agenda for the Annual Meeting and task group meetings is now available.
The WG studies feedbacks between biogeochemical (bgc) and physical processes at the ocean–ice-snow -atmosphere interfaces and within the sea ice matrix and aims to improve sea ice biochemistry models from the micro to the global scale by bringing together experimentalist and modellers. The WG is closely linked to SOLAS (Surface Ocean Lower Atmospher Study) and OASIS (Ocean Atmosphere Sea-Ice Snowpack Interaction). Activities within the task group on modelling are strongly linked with FAMOS (Forum for Arctic Modelling and Observational Synthesis).
Physical forcings of biogeochemical processes in sea ice and at sea ice – snow -atmosphere interfaces
BEPSII task groups
1. Methodological review;
2. Dedicated intercomparisons and intercalibration projects; and
3. Guide of Best Practices (living web document).
1. Produce new data inventories by collation of existing data;
2. Provide recommendations for standardized protocols and databases.
1. Recommendations from modelers to observationalists,
2. Review papers on major biogeochemical processes and their parameterization in models including: a) DIC/Alk separation during the freezing process, b) release and transfer of iron and other minerals c) light transfer in sea ice, d) ice algal release into the water, e) link to atmospheric chemistry, f) turbulent mixing in Arctic Ocean models.
3. Intercomparison of 1D models a) General ice-phytoplankton models, b) DMS, c) Physical: convective mixing (EoS), ice thermodynamics, advection processes,
4. Application in regional models with links to global & regional climate modeling.
