(Adapted from IAI-DIS home page)|
The IAI-DIS is a collaborative database system through which scientific
organizations in the Americas can contribute and share information about their
Global Change data holdings. It was designed as a network of national nodes,
interconnected by the Internet, offering anyone with a Web browser, free
distributed search capability at both directory and inventory levels.
Participating organizations in each country can remotely submit and update
metadata about their assets, also at no charge.
The DIS is coordinated by the IAI as a tool to foster and support international
scientific cooperation and joint research efforts in the area of Global Change.
The first IAI-DIS was installed at the IAI Directorate in Brazil and began
providing service in November, 1999. The Uruguay node was installed in August,
2000 and the other countries will implement their national nodes shortly
thereafter. The IAI hopes to have all member countries joining this effort in
the near future.
This dataset makes reference to the presentation used by Luis Marcelo Achite,
IAI-DIS Manager, where he presented general information about the IAI-DIS
system, its concepts, some technical details, and the architecture of the
Some background information about the IAI (main objectives) was presented as
well. Here is the list of presented itens: 1) The FGDC/CSDGM Standard used by
IAI-DIS; 2) The Z39.50 protocol used to search and retrieve information; 3)
Metadata Clearinghouse and 4) IAI-DIS System.

Taken from the 2008-2009 Progress Report:
Variations to work plan or objectives:
Each year since the 2002/03 season, permit restrictions have impacted substantially on both the work plan and ability of the program to meet its objectives. In this most recent year the following work was not able to proceed:
- weighing of pups to monitor growth
- marking of Hookers sea lions in order to better assess their predation impacts on fur seals.
Despite animal ethics approval to weigh pups, and mark sea lions we have now not been able to monitor inter-annual changes in pup growth rates in the population since 2002. This has impacted on the programs ability to deliver its obligations to the Antarctic State of the Environment reporting process (Indicator 32).
Location: Fieldwork was undertaken at Macquarie Island 08/09 summer. Activities included:
- Monitoring of the fur seal population including assessment of pup production, mortality rates and censusing the juvenile and adult population.
- Biopsies were taken from most pups for DNA assessment of species/hybrid identity, and phenotypic assessments were also made.
- Observations were undertaken to re-sight tagged animals, and to identify mother/pup pairs for long-term demographic studies (reproductive success and survival).
- Faecal samples were collected for on-going dietary studies.
Progress and timeline: As the Macquarie Island program is long-term, completion of any field component is seasonal, prior to the next field-stage that commences in November 2009.
Reproductive and survival data are being entered into a database and these data are currently being worked-up to develop correlates with oceanographic data and reproductive success and pup growth parameters, and determine annual changes in relative survival and the fitness costs of hybridisation.
Difficulties affecting project:
The permit modifications have significantly impacted the standardised monitoring program that has been in place for over 15 years. It appears that we will no longer be able to record important 'environmental context' data in the form of pup growth and maternal provisioning rates (indices of food availability). We will continue to seek approval to at least weigh pups over future seasons. Pup growth data to 90 days age correlate significantly with summer SSTs, which are likely to provide a good proxy for regional changes in primary/secondary production, and important environmental indicators of the implications of warming ocean temperature associated with climate change.
