Science Steering Group Co-Chairs and Members

The ISAC Science Steering Group (SSG) takes overall responsibility for planning and implementation of ISAC science activities, including the development of the science plan. Among other activities the SSG works to ensure the integration of the observation, modelling, and application elements of ISAC to produce an efficient, productive, and appropriately interdisciplinary program with a strong human dimension.

The SSG helps to coordinate international activities necessary to conduct a pan-arctic interdisciplinary program and works to coordinates with, and contributes to, ongoing and future impact assessments.

SSG membership aims for a balance between the physical and social sciences. The SSG may form working groups and panels to address specific questions or groups of questions in specific regions and/or requiring especially close scientific or operational cooperation.
