| Sumario: | <p>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
environmentally comprehensive reference dataset of modern census counts. The
Southern Ocean Radiolarian (SO-RAD) dataset includes census counts for 238
radiolarian taxa from 228 surface sediment samples located in the Atlantic,
Indian, and southwest Pacific sectors of the Southern Ocean. This compilation
is the largest radiolarian census dataset derived from surface sediment
samples in the Southern Ocean. The SO-RAD dataset may be used as a reference
dataset for palaeoceanographic reconstructions, or for studying modern
radiolarian biogeography and species diversity. As well as describing the
data collection and collation, we include recommendations and guidelines for
cleaning and subsetting the data for users unfamiliar with the procedures
typically used by the radiolarian community. The SO-RAD dataset is available to download from <a href="https://doi.org/10.1594/PANGAEA.929903">https://doi.org/10.1594/PANGAEA.929903</a> (Lawler et al., 2021).</p> |
