Southern Ocean modelling survey

In preparation of the SOOS/OCEAN:ICE Workshop on ice-ocean observation harmonization and future priorities agenda held in Copenhagen, DK, 17-19 September 2025, a targeted survey was conducted. Asking for input from the ocean and climate modelling community, this survey was designed to specifically support the coordination of field activities in the Southern Ocean for the forthcoming Antarctica InSync campaign and is aligned with broader strategic planning efforts ahead of the next International Polar Year. While the survey emphasized physical oceanographic processes, coupled interactions with other components of the climate system, for example, sea ice, ice shelves and atmospheric dynamics were considered as well. Contributions related to biogeochemical processes and ecosystem modeling were also encouraged. For pragmatic reasons, we definedthe Southern Ocean as the region south of approximately 50°S in the survey context.

This repository provides the original 98 responses collected (file formats .xlsx and .csv), a screenshot of the original questionnaire, and a set of slides summarizing the main results.

The survey was conducted using Google Forms. Graphics in "southern_ocean_modelling_survey_summary_slides.pdf" are based on the output generated by Google Forms based on the survey results.

We further acknowledge the kind support and endorsement by SOOS and CLIVAR offices and SSG and the sharing of the survey call across newsletters and mailing lists of SOOS, CLIVAR, SORP, OMDP, Antarctica InSync modelling, OCEAN:ICE, MISOMIP2, SOFIA and more.
