Digital preservation of geoscience information is important to ensure long-term access to valuable scientific data. For example, data from the 1975 Viking Mars mission was corrupted and unusable after 20 years. The presentation discusses the importance of digital preservation, outlines different types of digital information and threats. It also describes institutional repositories, digital preservation strategies like the OAIS model, and the current scenario in India. The research aims to test implementing an OAIS-compliant preservation layer in a geoscience institutional repository.
