The associated data highlights the sampling programme for the data acquisition campaign of Observation on the Aerial Platform for the SAMM1campaign (Aerial Marine Megafauna Monitoring) conducted by the PELAGIS observatory.

The associated data highlights the spatial influence of the dataset of the type “Visual Observations from an Aerial Platform” from the PELAGIS Observatory. These ranges represent the different areas of study on which the PELAGIS observatory conducted campaigns of visual observations from aerial platforms. Each area of study is associated with at least one campaign, with observers and geographical sectors linked to that campaign. Each sector is associated with bathymetric strips and transects related to each of the strips, with a few exceptions for the Indian Ocean region.

The associated data highlights the sampling programme for the data acquisition campaign of Observation on the Aerial Platform for the SAMM1and SAMM2 campaigns (Aerial Marine Megafauna Monitoring) conducted by the PELAGIS observatory (UMS 3462 ULR/CNRS). The sampling plan is composed of preestablished sampling strata and transects. These were drawn up according to the specific characteristic of the study area “Mainland France”, or FrM.
