    Monitoring intertidal ecosystems: Assessing spatio–temporal variability with Sentinel-2 and Landsat 8 by Carmen Zarzuelo, Alejandro López-Ruiz, María Bermúdez, Miguel Ortega-Sánchez, Isabel Caballero

    Published 2025-08-01
    “…The methodology involves selecting optimal satellite data, correcting for solar reflectance, identifying intertidal pixels using the Normalised Difference Water Index (NDWI) and classifying these zones into categories such as seagrass beds, mudflats, low marsh and high marsh. By comparing the effectiveness of Sentinel-2 and Landsat 8 datasets, the research addresses common challenges in land cover mapping of intertidal environments — such as cloud cover, reflectance variability and tidal influences. …”

    Disentangling the effects of eutrophication and natural variability on macrobenthic communities across French coastal lagoons by Jones, Auriane G., Schaal, Gauthier, Boyé, Aurélien, Creemers, Marie, Derolez, Valérie, Desroy, Nicolas, Fiandrino, Annie, Mouton, Théophile L., Simier, Monique, Smith, Niamh, Ouisse, Vincent

    Published 2024-12-01
    “…Using correlograms, linear models and variance partitioning, we found that lagoon hydro-morphology (connection to the sea and lagoon surface), which affects the level of environmental variability (salinity and temperature), as well as lagoon-scale benthic habitat diversity (using macrophyte morphotypes) seemed to regulate macrofauna distribution, while eutrophication and associated stressors like low dissolved oxygen, acted upon the existing communities, mainly by reducing species richness and diversity. …”
