HERRERA-ROMERO, J. A. et al. Salinity and soil properties of beach ridge in national marshlands in Mexico. Revista bio ciencias [online]. 2019, vol.6, e412.  Epub Mar 18, 2020. ISSN 2007-3380.  https://doi.org/10.15741/revbio.06.e412.

The delimitation of geoforms of beach ridges was performed by means of field recognition and support of satellite images in National Marshlands in Mexico. One hundred and two sampling points were selected, distributed in three transects, each involving the different beach ridges, as well as mounts and depressions (inter-bars). Each soil sample was analyzed for pH, ECe, texture, organic matter, cations and anions. They were organized by geoforms and basic statistics were obtained, such as mean, median, standard deviation, coefficient of variation and extreme values. The highest values of salinity, organic matter and clay were confirmed to be registered in geoforms of lower altitude by the influence of tidal and fluvial flooding, whereas geoforms of higher altitude such as coastal beach, dune and non-floodable high beach ridges had the highest values of sand and the lowest in clay, organic matter and salinity.
