Ocean Biodiversity Information System

Free global database of marine species observations, aggregated from a worldwide network of contributing institutions.

OBIS is a global, open-access database of marine biodiversity observations, governed by the Intergovernmental Oceanographic Commission of UNESCO through its International Oceanographic Data and Information Exchange programme. It aggregates species occurrence records, DNA sequences and environmental measurements contributed by a distributed network of roughly 38 national and thematic nodes across around 99 countries, supported by thousands of participating scientists and data managers. Users can query the database by species, location, dataset or publisher through an interactive mapping tool or a RESTful API, making it a standard reference for marine species distribution, conservation planning and ecosystem research. As an intergovernmental scientific infrastructure, access to all data is free.
