The SCAR Antarctic Biodiversity Portal (biodiversity.aq) is an international effort that seeks to increase our knowledge and understanding of Antarctic and Southern Ocean biodiversity. Biodiversity.aq establishes and supports a distributed system of interoperable databases, giving easy access through a single internet portal to a set of resources relevant to research, conservation and management pertaining to Antarctic biodiversity. Biodiversity.aq provides access to both marine and terrestrial Antarctic biodiversity data. It is a community of researchers, data custodians and developers from around the world that supports the mobilisation publication, retrieval and analysis of Antarctic and Southern Ocean biodiversity data in a free and open manner in line with the Antarctic treaty and the FAIR data Principles (Finable, Accessible, Interoperable, Reusable). We aim to create an information ecosystem of various data bases, data systems, web services tools etc that can be used by anyone with an interest in Antarctic and Southern Ocean biodiversity.
