Created by the Scientific Committee on Antarctic Research's (SCAR), an inter-disciplinary committee of the International Council for Science, the Marine Biodiversity Information Network (SCAR-MarBIN) is a collaborative web portal that provides free and open access to information on Antarctic marine biodiversity (http://www.scarmarbin.be). The portal started as a major Belgian contribution to the IPY, but grew into an international collaborative effort, with hundreds of scientists from around the world joining forces to build this unique web-based tool, enabling the community to share and publish information that is critical for research but also for conservation purposes.

Initiated by Drs. Claude De Broyer and Bruno Danis, SCAR-MarBIN is based at the Royal Belgian Institute of Natural Sciences in Brussels, Belgium. SCAR-MarBIN is home to the first complete Register of Antarctic Marine Species (RAMS), an authoritative list of species occurring in the Antarctic seas. RAMS is an online, interactive species list that contains information on more than 15,000 taxa and is constantly updated by more than 70 experts worldwide. RAMS data is shared with the World Register of Marine Species (WoRMS) that contains about 122,500 validated marine species names. Using the latest available visualization and database technologies, SCAR-MarBIN makes it possible to instantly download data and map the occurrence and abundance of polar marine organisms.

Huw Griffiths of the British Antarctic Survey said:

"SCAR-MarBIN is a unique tool that allows over a hundred international datasets to be searched and shown on one map. This is the first time such a huge amount of Antarctic biodiversity information has been brought together and is leading to a much better understanding of how and where life in this frozen ocean exists."

Since the data are standardized, a seamless exchange of information can take place with other online marine database networks, including the Ocean Biogeographic Information System (OBIS) or the Global Biodiversity Information Facility (GBIF).

SCAR-MarBIN is the information partner of the Census of Antarctic Marine Life (CAML), one of 17 projects of the Census of Marine Life. This partnership provided the mechanism to incorporate data generated by 18 CAML-flagged expeditions during IPY, but also laid the foundation for new synergies, which are serving to increase knowledge and understanding of marine life in the Southern Ocean.

If global climate change induces responses in Antarctic ecosystems, SCAR-MarBIN constitutes the best available data resource for assessment and documentation of any ecosystem response, and the identification of areas that may require further investigation or protection. On March 31, SCAR-MarBIN is releasing a new (beta) version of its data portal that will improve its usefulness for science, conservation and sustainable management.

Professor Andrew Clarke of the British Antarctic Survey said: "The best international science relies on effective communication. Given the remoteness of Antarctica and the many nations contributing to its study, a mechanism for ensuring fast and effective information flow is essential. SCAR-MarBIN provides that mechanism in an exemplary way. Since its inception SCAR-MarBIN has rapidly established itself as an invaluable tool for allowing a global community not only to gain access to data, but also to analyse and visualize it in innovative and powerful ways. Without doubt, SCAR-MarBIN is now the most important tool for marine ecologists and oceanographers working in the southern polar regions, and its newest version will, without question, increase its value to the scientific community."

With few resources, but a tremendous amount of support from the scientific community, SCAR-MarBIN has surpassed its objectives for the end of IPY. It now serves as repository for scientific information on Antarctic marine biodiversity, and proudly represents SCAR's contribution to the global effort to explore and preserve Antarctica as "a natural reserve, devoted to peace and science."
