The Southern Ocean RADiolarian (SO-RAD) dataset: a new compilation of modern radiolarian census data
Radiolarians (holoplanktonic Protozoa) preserved in marine sediments are commonly used as palaeoclimate proxies for reconstructing past Southern Ocean environments. Generating reconstructions of past climate based on microfossil abundances, such as radiolarians, requires a spatially and environmenta...
