The Register of Antarctic Marine Species (RAMS) has three main objectives: 1) Provide taxonomic data to various Antarctic biodiversity information systems. 2) Establish a benchmark of current taxonomic knowledge of Southern Ocean biodiversity. 3) Serve as an authoritative reference for Antarctic marine species classification.

Notas del editor
- RAMS primary role was to establish a benchmark of the present taxonomic knowledge of the Southern Ocean biodiversity, particularly important in the context of global change. This, in turn, allowed detecting gaps in knowledge, taxonomic treatment and coverage, and estimating the importance of the taxonomic impediment as well as the needs for more complete and efficient taxonomic tools.
