McGill Arctic Research Station (Expedition Fiord) (MARS) is a small research station operated by McGill University located near the centre of Axel Heiberg Island, Nunavut. It is located approximately 115 km (71 mi) southwest of Eureka, a weather and research station. It was first established in 1959 after scientists explored South Fiord (Expedition Fiord). The station contains a small hut, a cook house and two temporary structures. It can support 8-12 people and gives them access to the research activities. The current activities are glaciology, climate change, permafrost, hydrology, geology, geomorphology, limnology, planetary analogues, and microbiology. Today, the station is only used in the summer months so there would be enough power generated from the solar panels.
