InterRidge has just begun its second decade. The science plan for this decade identifies the themes (represented by working groups, the mainstay of InterRidge) that will constitute the core of research during this period. The basic structure of InterRidge are its working groups. A working group comprises a working group chair or co-chairs who drive the progress of the group and report back to the Steering Committee, and the working group members. The scientists come from various universities and research institutes around the world, and their expertise is diverse but pertinent to the project the working group is tackling. This ensures that ridge-related research projects are addressed from different perspectives.
| Theme | Objective | End | WG-Chair |
| Utraslow spreading ridges | concentrate on the particular scientific and coordination and coordination problems posed by ultra-slow ridges | ongoing | Jon Snow, Houston, USA |
| Biology | increase international collaboration in hydrothermal biological studies and work on integrating ridge-crest biological and geological research | ongoing | Nicole Dubilier, Bremen, Germany Chuck Fisher, Penn State, USA |
| Monitoring and observatories | promote long term ocean bottom observatories, establish a long-term observatory in the Atlantic | ongoing | Javier Escartin, IPG, France Ricardo Santos, Azores, Portugal |
| Deep earth sampling | strengthen the ties to, and use of, global deep earth sampling facilities such as IODP, ICDP, etc. | ongoing | Benoit Iledefonse, Montpellier, France |
| Biogeochemical interactions at deep sea vents | address questions of biogeochemical interactions in different MOR and BAB environments and link scientists and their needs for technologies and sampling time | ongoing | Nadine le Bris, IFREMER, France |
