Oyambre estuary restoration (N Spain)

This dataset contains information on the abundance and biomass of benthic invertebrates from the Oyambre Estuary (Cantabria, northern Spain). Sampling was conducted between 2010 and 2019 at eight stations distributed along the estuary, with variable sampling frequency over the study period. The data were collected as part of the project "Ecological Monitoring of La Rabia Estuary in the Oyambre System," designed to assess ecological responses to hydrodynamic, morphological, and environmental changes resulting from the reopening of water channels under the new bridges of La Rabia and El Capitán estuary arms. The ecological monitoring was carried out in parallel with physical surveys to evaluate the progress of the estuarine restoration process.
