The document discusses two biodiversity information networks - SCAR-MarBIN and ANTABIF - that provide free and open access to Antarctic biodiversity data. They follow a general philosophy of building an electronic ecosystem that exposes biodiversity data and metadata in multiple contexts through community collaboration and standardization. The networks have developed web portals, taxonomic and geospatial databases, field guides, and tools that follow open standards to facilitate data sharing and discovery. Projects aim to georeference genetic data and develop a Southern Ocean biogeography atlas.
