High time and space resolution analysis of Austre Lovén glacier seasonal and interannual dynamics (Svalbard - 79°N)
COM International audience Austre Lovén glacier is a small valley glacier in Svalbard. It has been retreating since the little ice age. Over the last five years, an extensive monitoring program has been conducted in this glacier basin. A network of 36 ablation stakes has been distributed at regular...
