The Marine Biological Association (MBA) of the UK is a charitable research organisation working to ‘promote scientific research into all aspects of life in the sea, including the environment on which it depends, and to disseminate to the public the knowledge gained’. The MBA developed DASSH (the Archive for Marine Species and Habitats Data), which is the UK Marine Data Archive Centre for benthic survey data of both species and habitats. DASSH provides digital archive facilities for benthic datasets and a digital repository for benthic images and video. Website: http://www.mba.ac.uk/about/ and http://www.dassh.ac.uk/
