The proper preservation of both current and historical scientific data will underpin a multitude of ecological, economic and political decisions in the future of our society. The SCIDIP-ES project addresses the long-term persistent storage, access and management needs of scientific data by providing preservation infrastructure services. Taking exemplars from the Earth Science domain we highlight the key preservation challenges and barriers to be overcome by the SCIDIP-ES infrastructure. SCIDIP-ES augments existing science data e-infrastructures by adding specific services and toolkits, which implement core preservation concepts, thus guaranteeing the long-term access to data assets across and beyond their designated communities.
