Welcome on the Website of the Underwater observers network (ROSM)

Jean-Michel Cousteau "I hope the Underwater Observers Network and its members continue their work and realize the value of their contribution to us all." Read more...

In order to reach this goal, the ROSM is currently working on a geo referenced census of aquatic species living in our water

This essential knowledge needed to protect our aquatic environments is unfortunately generally lacking and your help is needed to gather this precious information. We need you to let us know which aquatic species you observe while doing your outdoor activities, and not only the special ones but also the common ones, those that you see day after day. This information is needed because to detect changes we need baseline data. And if the only observations which are noted are the more attractive species, we might not be able to detect changes, and consequently act in time.

Furthermore, your contribution not only will help us to better know about the geographical distribution of our aquatic species but it will also allow those doing outdoor activities to know about the species they might see in sites they may not know. So we are inviting you to join the ROSM and share your observations.
