Meiofauna, nematodes and associated sediment characteristics of the mangrove-colonized banks of Cayenne estuary (French Guiana) during the wet season of 2022

In March 2022, the working group has been sampling in French Guiana, namely in the Cayenne estuary during an unforeseen rainy season which marked the rainfall record of the past decades.

The locations chosen along the estuary mirrored the opposite marine and terrestrial inputs as well as the influence of the city of Cayenne at the mouth of the estuary. The transects at every sampling location aimed at representing the local heterogeneity of the mangroves, from uncolonized bare mud to dense roots and tall adult trees. Biotic (meiofauna and nematodes) as well as abiotic parameters (pH, redox potential, salinity, CHN, stable isotopes, grain size and pigments) have been sampled for.
