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 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.
|Starting date||Ending date||Type of documents||sampling frequency (if ledger)||Scanned (YES/NO)|
