Welcome to OBIS Canada - Where You Can Explore Canadian Marine Biodiversity!

OBIS Canada is the Canadian regional node of the International Ocean Biogeographic Information System (OBIS). OBIS is an international federation of organizations and people sharing a vision to make marine biogeographic data, from all over the world, freely available over the internet. It functions as a web-based provider of global geo-referenced information on marine species. It provides a single entry point to query expert databases on species and habitats and provides a variety of tools for visualizing relationships between marine species and their environment. OBIS is also the information component of the Census of Marine Life Program.

OBIS Canada is responsible for dissemination of data and information about the biodiversity of Canadian waters. Its main functions are to foster the on-line provision of marine species data from the Canadian region into the OBIS portal, and to provide an access for Canadian users to the international OBIS data network. OBIS Canada is also the information component of the Canadian Center for Marine Biodiversity.
