Whether in solid or liquid or gaseous form, matter can convert radiative energy by the absorption process or it can transmit it with the possibility of a change in direction through the scattering process. When added up, these optical properties can tell you a lot about what a medium is made of. Continue reading Shining their own light

Rapid, dramatic changes of surface sea ice
During the Arctic winter, a snow-pack forms over the sea ice. Typically 20-30 cm deep, it is thin relative to the thickness of the ice below. However, this snow layer plays a fundamental role in different domains. Snow is composed of small ice crystals surrounded by air. This very simple structure leads to two important physical properties: Continue reading Rapid, dramatic changes of surface sea ice
A revisited way for bear-watching
When working in the Arctic you have to expect things to break or not to go as smoothly as you would like. Indeed this happened to us quite a few times, here is our most recent eventful day on the ice… Continue reading A revisited way for bear-watching
