How to use the Argonautica web site and its data

Each week (on Thursdays), at http://argonautica.jason.oceanobs.com, Argonautica provides: :

The locations and maps are filtered:
- by beacon "group" (e.g. penguin or buoy ),
- by period; default period is the last 12 months. However, you can extend it up to the first tracking recorded in Argonautica (2004), or limit it to the last month, or last week.
- by name (according to the name given to an animal or the oceanographic beacon); no two beacons are affected the same name.
