Short summary

We developed a new method to study how light interacts with sea ice using a compact 360° camera. By lowering this camera into drilled holes in ice, we captured detailed light patterns inside different ice layers. Our research revealed how light is absorbed and scattered in both Arctic multi-year ice and thinner, seasonal ice in Quebec. These findings improve our understanding of sea ice structure and its role in the climate system, helping in the representation of sea ice in models.
