Orthomosaics of the study area were generated by drones on 19 September 2024 and 18 September 2025. They were created from 895 images (2024) and 1,282 images (2025), captured at altitudes of 120 meters (2024) and 100 meters (2025) using the DJI Mavic 3E RTK (2024) and Mavic 3M RTK (2025) drones. The ground resolutions were 3.19 cm/pixel (2024) and 2.63 cm/pixel (2025). The surveyed area covers approximately 1 km², and the orthomosaics were resampled to a resolution of 10 cm/pixel.

The multispectral images of the study area were acquired by drone on 18 September 2025 using the DJI Mavic 3M RTK. The orthomosaic was generated from 5,128 images across five spectral bands (Green, Red, Red Edge, Near-Infrared (NIR), and Alpha), captured at an altitude of 100 meters (2025). The ground resolution achieved was 4.568 cm/pixel, covering a surveyed area of approximately 0.94 km². The Digital Surface Models (DSMs) were resampled to a resolution of 10 cm.

Digital Surface Models (DSMs) of the study area surveyed by drone between June 2024 and March 2025. Each pixel contains the elevation value corresponding to the terrain at the time of the mission. These DSMs were generated from around 1,300 images (depending of the survey) acquired using the DJI Mavic 3E RTK drone, with a resolution of 3.2 cm/pixel. The surveyed area covers around 2.1 km². The campaign was conducted on the highest tides of each month. The drone acquisitions were carried out by Nicolas Lachaussée from the LIENSs UMR Drone Platform. Photogrammetric processing was performed by Natacha Volto (LIENSs) using Agisoft Metashape software. The vertical coordinate system is NGF IGN69. The vertical accuracy (RMSD ~ 3 cm), calculated using around 100 control points, randomly distributed across the study area. It is derived from the vertical difference for each control point between the value measured with the DGPS SP80 and the value extracted from the photogrammetry-generated DSM. These drone surveys were carried out as part of the thesis of Loës Le Goff Le Gourrierec supervised by Xavier Bertin.

Plusieurs paramètres environnementaux ont été collectés dans les marais des 3 sites d'études PAMPAS (Tasdon, Ars, Brouage) pour chaque coup de pêche de poissons entre 2019 et 2021 : température (air, eau de surface, eau de fond), oxygène (de surface et de fond), salinité (de surface et de fond), hauteur d'eau, turbidité, couverture d'algues et couverture de ruppia sp..

Dans le cadre de l'ANR PAMPAS, l'effet de la submersion sur les communautés planctoniques a été étudié dans plusieurs bassins des marais de l'Houmeau (Nord de La Rochelle).

Caractérisation des structures des communautés de poissons selon l'état d'exploitation et les degrés d'immersion des marais de Charente Maritime, entre 2019 et 2021, dans le cadre de l'ANR PAMPAS.

Dans le cadre de l'ANR PAMPAS, entre 2019 et 2020, une caractérisation des fonctions écologiques de vasais de premier rang dans le Fier d'Ars (île de Ré) a été réalisée : - un vasais situé dans la réserve naturelle de Lilleau des Niges, dans le nord du Fier d'Ars - un vasais de l'Ecomusée du marais salant, dans le sud du Fier d'Ars

Caractérisation des communautés de poissons dans les marais de Tasdon (La Rochelle) en 2019, dans le cadre de l'ANR PAMPAS : - dans le 'Lac de Villeneuve', station 2, réservoir d'eaux pluviales, situé en zone péri-urbaine de La Rochelle, relié à la rivière, 'La Moulinette', en 2019 - en aval de la rivière de La Moulinette, La Rochelle, entre 2019 et 2021

Des prélèvements d'eau ont été réalisés en même temps que le suivi du plancton, à savoir sur les 3 sites d'études de Pampas, entre 2019 et 2022, pour mesurer les sels nutritifs : silicates, nitrates, nitrites, phosphates et ammonium
