On World Ocean Day, 8th June 2021, we jointly organised a webinar and celebrated the collaboration between the International Seabed Authority (ISA) and OBIS. The ISA is now one of the 32 OBIS nodes and will publish the biodiversity data collected by the deep-sea mining contractors, to OBIS. This is an important milestone for OBIS and we welcome our new member. The ISA is also the first UN body that joins the OBIS network.
