SC-ADM coordinates the Antarctic Data Management System (ADMS). The ADMS is composed of:
The NADCs are a link between Antarctic scientists and the AMD. Antarctic scientists are responsible for creating metadata, but are also the major beneficiaries of the system.
The ADMS is the most appropriate starting point for overall Antarctic data management. It directly addresses the problems of awareness and access to relevant data.
However, the development of a comprehensive directory of Antarctic data is not a trivial task. It requires the commitment and participation of all SCAR member countries, and significant ongoing resources. Failure to provide this commitment and support will inevitably lead to unnecessary duplication of expenditure, lost opportunities for cooperation, and a lower return on investment from Antarctic science.
The roles of the constituents of the ADMS are clearly defined.
The ICSU World Data Center system and groups such as the World Meteorological Organisation are data repositories. They contain a subset of data collected from Antarctic research, but data management can vary considerably depending on discipline and local factors.
The ADMS is a data index providing a unique, consistent and uniform source of information about all Antarctic data (multi-disciplinary and multi-national), no matter where they are located.
The IDN, implemented by the national space agencies of the United States, Europe, and Japan under the auspices of the Committee on Earth Observation by Satellites (CEOS), provides universal access to data of different disciplines and located in different countries. The ADMS is an extension of the IDN. Within the IDN, the Global Change Master Directory (GCMD) is responsible for the development of DIF metadata, and support.
