IASC and SCAR (the Scientific Committee on Antarctic Research) have a wide range of members, activities, and partners. These SCAR and/or IASC affiliated groups were given the opportunity to share their work with the broader community at Polar2018, beyond the scientific program of the conference. Accordingly, upon request, each of these groups was allocated a poster as part of our “PolarExpo.” Posters were hung during the business meetings and Open Science Conference at Polar2018 back in June.
