 several kilometres south of Neumayer-Station II. The station's assembly kit was transported to its current position beginning of November 2007. It is moving with the shelf ice at about 200 meters per year towards the open sea.

After almost 10 years of work on the project (beginning October 1999); including conception, environmental impact investigation, planning and construction phases, regular operation of the station began on 20 February 2009. The station replaces the Neumayer-Station II and the Georg-von-Neumayer-Station that preceded it. The expected lifespan of the station is 25 to 30 years and the entire project is estimated to cost 39 million Euro

Construction phase

The station was constructed 6 m (19.7 ft) above ground on a temporary two-level platform and now sits on 16 columns; each hydraulic column rests on a solid snow surface. A garage and further technical equipment are located within a snow cavern below snow level at the front of the station. The moving concrete supporting feet are powered by hydraulic machinery. Through an annual lifting procedure of 80 to 100 cm (31.5 to 39.4 in) it is expected to prevent new snow from causing the platform to sink.

The station will run all year round and includes 210 m² (2,260.4 sq ft) of laboratory surface, divided into 12 compartments; in total, double the area of previous stations. Within the 15 accommodation containers there is room for 40 occupants to sleep. All inner rooms of the platform are built as self-contained units, some of which have aligned connecting passages, depending on their size. The compartmentalized interior of the station is enclosed in titanium protective sheet metal as thin as paper, with insulating Polyurethane

 by March 2009. For construction, a work crew of 90 specialists was necessary. By mid January 2009 exterior work on the station was completed, so that further improvements to the 99 interior containers could continue unaffected by the weather.

Interior

In addition to the previously mentioned laboratories and accommodation areas, there is a south-facing lounge with many windows, a washing room containing two washing machines and two dryers, a Sauna, an IT-room, showering and washing rooms, a dining room with a serving window connected to the kitchen, a conference room, medical treatment and operating rooms, various storage rooms, a large refrigerating area, a dressing room, a heating-system room, a schooling and planning room and finally a water treatment room.

  • Remote stations

    At Neumayer-Station III, in order to minimize any affect that the main station's regular operations might have on the accuracy of scientific projects, small remote platforms are set up at a distance of 900 to 1500 m (2,952.8 to 4,921.3 ft) from the main station. Magnetic-, seismic-, trace element- and acoustic-research are the chief research foci of these remote stations.
