Light is a key mechanism shaping many aspects of the natural world – from ecosystems to individual behavior and physiology. Phases of continuous light and dark during the annual cycle define high latitude systems and physical character istics of light differ at high latitude across the year.

In Arctic systems, however, we have an incomplete and frag mented understanding of how light structures natural processes, and multipl e disciplines investigate how light organizes environmental, ecological, an d organismal processes. Our aim is to consolidate the knowledge of the role that light plays in Arctic ecosystems and societies by bringing together r esearchers and knowledge holders in the ArcticLight Network that have exper ience with marine, terrestrial, human, and cryospheric systems.

This interdisciplinary network will lead to a found ation from which we can build a better understanding of the role of light i n a rapidly changing Arctic and aid in predictions of ecosystem and biodive rsity change for the benefit of society.

The workshop is co-funded through the IASC cross-cutting funds with contributio ns from the IASC Cryosphere WG, Marine WG, and Terrestrial WG.
