We focus on the active layer dynamics of three sites in Maritime Antarctica. We examine air and active layer temperatures and snow thickness at each site. Active layer regime depended on snow conditions, which were influenced by topography. These factors condition geomorphological processes at the lake catchment scale. Lake sediments record geomorphologic, environmental and climatic signals.
