Seafloor observatories from experiments and projects to the european permanent underwater network EMSO
| Instrumentation Viewpoint
The establishment of a global network of seafloor observatories will help
to provide the means to understand the ocean, and the complex physical, biological,
chemical, and geological systems operating within it. This is a challenge for the
opening decades of the 21st century. The EC experience on seafloor monitoring is
outlined since the early stage (beginning of ‘90s). In particular, the attention is focused
on the GEOSTAR experience, describing the technical characteristics and the
sensors used in experiments. Some recent projects are detailed. Finally, the European
effort towards permanent underwater network EMSO, one of the large-scale
research infrastructures included in the ESFRI Roadmap, is also discussed. All the
previous activities are framed in this context.
