| Zusammenfassung |
| A major driver in the advancement of geophysical sciences is improvement in the quality and
resolution of data for use in scientific analysis, and discovery, or for assimilation into or
validation of, empirical and physical models. The need for more and better measurements
together with improvements in technical capabilities are driving the ambition to deploy arrays
of autonomous geophysical instrument platforms in remote regions. This is particularly
true in the southern polar region where measurements are presently sparse due
to the remoteness, lack of infrastructure and harshness of the environment. The
need for the acquisition of continuous long-term data from remote polar locations
exists across geophysical disciplines and is a generic infrastructure problem. The
infrastructure, however, to support autonomous instrument platforms in polar environments
is still in the early stages of development. We report here the development of an
autonomous low-power magnetic variation data collection system. Following two years
of field test at South Pole station, the system is being reproduced to establish a
dense chain of stations on the Antarctic Plateau along the 40- magnetic meridian
(conjugate to the magnetic stations along the west coast of Greenland). The first
two stations have been deployed and are operating. The system is desaigned to
operate for at least five years unattended and to provide data access via satellite
communication. The system will store 1-second measurements of the magnetic field variation
(< 0.2nT resolution) in three vector components plus a variety of engineering
status and environment parameters. We believe that the data collection platform can
be utilized by a variety of low-power instruments designed for low-temperature
operation. The design, technical characteristics and operation results are presented here. |
