University of Gothenburg leads a scientific network of Long-Term Ecological Research (LTER) sites for genetic monitoring of hard-bottom communities (ARMS-MBON). The network deploys so-called Autonomous Reef Monitoring Structures (ARMS) along the coastline of Sweden, Denmark, Norway, and Finland. The aim of ARMS-MBON is to collect comparative data for the assessment the status and change on the seafloor, using genetic methods. All data collected by the network wil be made accessible to SBDI. ARMS-MBON is now part of GEO BONs global Marine Biodiversity Observation Network (MBON).
