The paper documents identified in the summary barplot (grey / black bars) come from the Shom archives (up-to-date inventory). It is possible that several types of documents concern the same period (ledger(s)/tide gauge charts) and their stage of dematerialisation (scanned or not) are possibly different: refer to the table below to find out.
The inventory of analog data shown in pink on the figure bottom corresponds to documents which potentially contain water level information and identified in others archive centers than from Shom's. This list, relating to the ILES MARQUISES is available here
The inventory of Shom archives is in progress. Possibliy, this list could change in future. When documents are ledgers, the sampling frequency is noted if reported during the inventory.
