Relative abundances of benthic foraminifera in response to total organic carbon in sediments: Data from European intertidal areas and transitional waters

We gathered total organic carbon (%) and relative abun- dances of benthic foraminifera in intertidal areas and tran- sitional waters from the English Channel/European Atlantic Coast (587 samples) and the Mediterranean Sea (301 sam- ples) regions from published and unpublished datasets. This database allowed to calculate total organic carbon optimum and tolerance range of benthic foraminifera in order to as- sign them to ecological groups of sensitivity. Optima and tolerance range were obtained by mean of the weighted- averaging method. The data are related to the research article titled “Indicative value of benthic foraminifera for biomoni- toring: assignment to ecological groups of sensitivity to total organic carbon of species from European intertidal areas and transitional waters”
