How do I use the Argonautica website and its data?

Every week (on a Thursday), Argonautica releases the following information on, Argonautica provides:

The locations and maps are filtered:
- by beacon "group" (e.g. penguin or buoy ; different species can appear in a group - e.g. emperor or royal penguins ; note that some grouping depends on the French name of some species: elephants seals are "sea elephants" in French, so they were not listed within the seal group, but by themselves)
- by period; the default period covers the previous 12 months, but it can be extended to the start of tracking records (November 2004), or restricted to the last month or week.
- by name (according to the name given to an animal or the oceanographic beacon); no two beacons are affected the same name.
