There is an Apple hut on the Leonie Island, which was provided by the Dutch Antarctic Division during a joint working programme. There was also a Melon Hut on Lagoon for the same purpose, but this has now been moved to Anchorage Island. Nunatak was the BAS’s house band. The five person indie rock band is part of a science team investigating climate change and evolutionary biology on the Antarctic Peninsula. They are chiefly known for their participation in Live Earth in 2007, where they were the only band to play in the event's Antarctica concert. Being located just South of the Antarctic Circle, the weather is cold year round. Temperatures in summer barely go over freezing. The station has a 900 m (2,950 ft) crushed rock runway, with an associated hangar and bulk fuel storage facility, and a wharf for the discharge of cargo from supply ships. There is a transitory summer population of scientists and support staff who reach Rothera either by ship or through use of a de Havilland Canada Dash 7 aircraft flying from the Falkland Islands. From its inception until the 1991/1992 summer season BAS Twin Otter aircraft used the skiway 300 m (about 1000 ft) above the station on Wormald Ice Piedmont. With the commissioning of the gravel runway and hangar in 1991/1992 air operations became more reliable and access to Rothera was greatly improved through a direct airlink from the Falkland Islands. The Twin Otters mainly fly south of Rothera, via a network of fuel depots, most of which are manned. Heading south of Rothera, the first stop would be Fossil Bluff, then Sky Blu. The Dash 7 will make approximately 20 flights a season to Stanley during the summer, bringing in scientists, support staff, food and equipment. When not tasked for these flights, the Dash can fly to Sky Blu in one hop, landing on the Blue Ice runway, significantly enhancing the range of the Twin Otters by depositing fuel and equipment in much larger quantities.
