Ocean Biodiversity Information System

OBIS is a global open-access data and information clearing-house on marine biodiversity for science, conservation and sustainable development.



The Ocean Biodiversity Information System (OBIS) is one of our flagship data systems. OBIS is a global data platform that integrates, quality controls and provides access to over 60 million occurrence records of 135,000 different marine species and that number is growing by millions every year. OBIS is built by the contribution of thousands of scientists who collaborate with data managers to make scientific data available for research, management and public awareness. Every year, OBIS is used in over 100 scientific papers. The UN World Ocean Assessment and the assessments as part of the Intergovernmental Platform on Biodiversity and Ecosystem Services all use OBIS to report on the state of our ocean.
