 Neumayer Station III in December 2009
|
|||
The Neumayer Station III , shortly Neumayer III , named after the geophysicist Georg von Neumayer , a German polar research station of the Alfred Wegener Institute in the Antarctic . It is located in Atka Bay on the Ekström Ice Shelf , about 200 meters thick , about 6 kilometers south of the replaced Neumayer Station II, and drifts 157 meters per year towards the open sea with the flowing ice shelf.
After a project period of almost ten years (beginning in October 1999), consisting of a conception, an environmental impact study and the planning and construction phases, regular station operations began on February 20, 2009. The operating time is designed for 25 to 30 years, the entire station with project planning cost 39 million euros.
Station construction
Stilts
The outer part of the station consists of a platform 6 m above the ground surface with two floors, which stands on 16 height-adjustable stilts . The height of the stilts, which are individually adjustable by means of hydraulics, have wide steel plates at their feet, which distribute the weight of the platform over a wide area in order to prevent it from sinking into the snow. To raise the structure, they are retracted individually, filled with snow and then extended again. The advantage of this type of construction is that no snow drifts are deposited over or on the building, since the wind that blows the snow into the space under the platform also blows it out again. Previous buildings in Antarctica that did not stand on stilts have been regularly snowed in over time.
An annual lifting process of 200 cm through snow relining prevents the platform from sinking into the fresh snow.
underground car park
The platform's stilts stand beneath the surrounding snow cover in a ditch that also serves as an underground car park for snow groomers , snowmobiles and non-motorized transport sleds, as well as a cooling room . The side walls of this trench are secured by sheet piling made of metal. The ceiling of the garage is covered by metal plates, between which the stilts protrude. Above this is the snow cover at ground level.
platform
The station is operated all year round and, with 210 m² of scientific laboratory space , spread over 12 rooms, is twice the size of its predecessor. There are 40 beds in the 15 accommodation rooms. All interior spaces on the platform consist of containers which, depending on the size of the room, are connected without adjoining interior walls or with a passage and border a connecting passage in the middle. This construction is surrounded by a protective sheet metal shell with an insulating rigid polyurethane foam filling . Hot-dip galvanized steel was chosen as the material because it not only defies the abrasive winds, but also the high UV radiation at the pole. The photo "Scaffolding cut .." in the picture gallery below shows the upper edge of the trench in the snow through the green metal girders in Antarctica. All areas below are later below the snow surface.

The above-ground station operation of the Neumayer III is predominant in the Antarctic and will also be implemented at the new stations, such as the Amundsen-Scott South Pole Station and the largely privately financed new Belgian Princess Elisabeth Station .
Interior decoration
In addition to the laboratory and accommodation rooms mentioned, there is a comparatively large lounge with many windows facing south, a laundry room with two washing machines and two tumble dryers, a sauna, a server room, shower and laundry rooms, a dining room with a hatch into the kitchen Meeting room, a patient treatment room and an operating room, various storage rooms, a large cold room, a changing room, a boiler room, a training or planning room and a water treatment room.
In the ward hospital, the ward staff doctor can perform difficult operations herself in an emergency.
Outdoor stations and webcam
In order not to influence the measurement results through the station operation, there are smaller platforms at a distance of 900 m to 1,500 m in a similar arrangement to that of Neumayer Station II.
Amateur radio service
The communication facilities also include an amateur radio station with the extra-territorial German amateur radio call sign DP0GVN. It may be operated by members of the station crew in their spare time according to their own preferences.
Since the beginning of 2018 is also under the same call sign a WSPR - Bake in operation.
Research operation
overview
Research has been ongoing in the individual observatories at the Neumayer stations since 1981 . In addition to the main fields of meteorology , geophysics and air chemistry , which have been researched since the 1980s , there has also been research on infrasound since 2003 and on marine acoustics since 2005 .
Penguin Colony Research
One of the research focuses is on the penguin colonies of the Antarctic and the effects of climate change on their habitat.
Glacier research
Snow samples are taken every day at a distance of 1.5 km from the station in order to find out exactly how new snow is transformed into glacier ice.
Outstations
The outstations are long-term observatories, where magnetics, seismics, trace substances and acoustics research is carried out. The station operates a webcam , which can be used to call up the current exterior views of the station and films from the last 24 hours. The current weather data is also made available on the Internet (see web links ).
There is also an air chemistry observatory in a small research container in which the greenhouse gases in the atmosphere, especially greenhouse gases that are harmful to the climate, are analyzed.
Mars research
Apart from that, the Neumayer station is also suitable for research for future missions to Mars; For example, vegetables are grown in the artificial garden "Eden ISS", which only grow under artificial light and with a nutrient solution without soil. The fresh food obtained is used to supply the station, which otherwise only comes from frozen food.
Assembly
In Bremerhaven, the main components were set up on a trial basis and their function tested. The main part of the building materials shipped in individual parts as well as the heavy construction equipment were delivered to the destination from the beginning of November 2007 to the end of January 2008; the latter left the Ekström Ice Shelf in February 2009. A construction team of 90 specialists was sent to the Antarctic for installation. In mid-January 2009, the external work on the station was completed, so that the further expansion of the 99 containers located under the outer shell could take place largely independent of the weather. On February 20, the station was opened for use during a ceremony in Berlin in the presence of the then Research Minister Annette Schavan .
patent
The owner of the patent on which this research station is based is the "Alfred Wegener Institute for Polar and Marine Research Bremerhaven, Germany". It runs under the name "Useful structure for permanent snow areas" and was invented by Ralf Siegmund as part of his work at the Alfred Wegener Institute. The patent runs under the number DE 10358631 B3 and was applied for on December 11, 2003.
