OBIS Deep Sea

Open in mapper Explore occurrences

The Deep-sea OBIS node is one of the global thematic nodes of the Ocean Biodiversity Information System, hosted at the OBIS secretariat, and managed by the Senckenberg Research Institute and Natural History Museum. The deep-sea OBIS node aims to provide a single integrated access point to high-quality data and information on the diversity, abundance and distribution of all deep-sea organisms and their ecosystem properties, including habitat and environmental characteristics. The further development of this deep-sea OBIS node and data portal is a shared responsibility of the wider deep-sea scientific community, and is supported by the International network for scientific investigation of deep-sea ecosystems (INEEP project, http://www.indeep-project.org/) and the Deep Ocean Stewardship Initiative (DOSI, http://dosi-project.org/).
