The US Antarctic research community has developed disciplinary repositories with excellent tools for specific datasets. Many datasets do not fit into these disciplinary repositories, but provide valuable, often unique data that would otherwise be difficult to preserve or find. The US Antarctic Program Data Center (USAP-DC) is funded by the National Science Foundation (NSF) and provides services to help scientists document, preserve, and disseminate all Antarctic research data including those for which no disciplinary repository exists. Thus, these datasets are preserved for future access. We provide DOIs for these datasets, and increase findability and visibility of the dataset by sharing through various data portals including the Antarctic Master Directory, DataOne and serving of schema.org in dataset landing pages. We recently improved our search interface to include a better map-based search option on the USDAP-DC web page. USAP-DC also maintains project pages for NSF awards and for a groups of collaborative research awards that include basic information of these projects and provide links to datasets hosted by different repositories including those hosted at USAP-DC. This improves findability of data linked to specific projects even if they are distributed across different repositories.
