Description
Summary:Planktonic foraminifera census data have been widely used to reconstruct changes in ocean ecosystems as well as ocean chemistry and circulation through calibration functions. Here we analyse new core‐top census data from 22 sites in the western South Atlantic, improving the geographical coverage and spatial resolution of the environmental gradients from the region covered by the Brazil–Malvinas Confluence (~38°S–53°W). We combine them with previous data to provide an up‐to‐date compilation of the western South Atlantic planktonic foraminifera–calibration data set. We study the relationship between the assemblages present in the core‐top samples and the most dynamic environmental variables from the region to establish the environmental variable(s) more resolved by the assemblages. Therefore, we develop and assess a new calibration function using the data set and testing several statistical models at different water depths. Our results reveal that the distribution and abundance of the species in the ... : Supplement to: García Chapori, Natalia Luz; Laprida, Cecilia (2021): Planktonic foraminifera assemblages from the Brazil–Malvinas Confluence: palaeoceanographic implications of sub‐surface temperature reconstructions in the western South Atlantic.
