How do I use the Argonautica/ArgoHydro website and its data?

Every week (on a Monday), Argonautica releases the following information on https://argonautica.jason.oceanobs.com/html/argohydro/welcome_uk.html, Argonautica provides:

• data on rivers and lakes

The data are sorted:
- by project, grouping several measurements points in each project, over e.g., the same river along its flow, but not only -- it can be rivers under similar or different climates, or a lake and the rivers feeding it, etc.)
- by "station", i.e., a measurement point at a given place, using a given instrumentation. For now, only satellite water level measurements are available.

• How (in practice) can you use ArgoHydro data?
• Displaying data
• Potential scientific uses of such information
