Biogeography - mapping of Holocene Planktonic Foraminifera using the ForCenS Database

ForCenS is a database of 4205 assemblage counts of planktonic foraminifera >150┬Ám in Holocene sediment samples compiled by Siccha & Kucera (2017). The database is available for download from Pangaea and is fully documented by Siccha & Kucera (2017). This interface plots data from the database onto a world map to provide an overview of the biogeography of the species. The data in the database is the frequency/relative abundance of each taxon within the planktonic foram assemblage. The original data comes from a wide range of published studies (including CLIMAP, MARGO BUFD and ARL947), it was taxonomically harmonised, dereplicated and treated for numerical and other inconsistencies. Samples with only partial assemblage counts or suspect data were eliminated, see Siccha & Kucera (2017) for full details. The taxonomy employed is the same as that documented on mikrotax, but with some additional categories (e.g. for coiling direction of some species).
