Colonization devices were deployed in selected patches with markers for a different succession study. Deployments and recoveries of devices with Alvin dive numbers and maximal temperatures (in °C) measured are listed, as well as corresponding figures and assessment of viability of most tubeworms in a specific clump. N/A, data not available; T, temperature.
