Summary of documents/data relative to: LIBREVILLE (GABON)

Plot Explanations:

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 LIBREVILLE is available here

The digital hourly water levels (blue bars) are those present in the Shom database. These data may correspond to measurements directly acquired in digital format and validated by the Shom (generally post-2000). They also could be the result of digitisation of paper documents carried out in the past for the needs of Shom. In the latter case, it is possible that no paper document is identified while there is digital data (either the documents are not yet inventoried, or these documents are not the property of Shom and therefore not identified during the inventory).

Detailed list of documents related to water level measurements, carried out at LIBREVILLE , from Shom archives:

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.
