IN2017_V01: Radiolarian Abundance and Taxonomy from Antarctic Ocean Voyage

Quantitative radiolarian data were collected during the 2017 RV Investigator voyage IN2017_V01 in the Southern Ocean. The dataset, generated by Kelly-Anne Lawler with taxonomic assistance from Dr. Giuseppe Cortese, provides absolute radiolarian abundance and species-level identifications for paleoceanographic analysis. Samples were processed using a specific microscopy method and taxonomic nomenclature from Lazarus et al. (2015).

Use Cases

• Reconstructing past ocean conditions based on radiolarian assemblage data.
• Calibrating radiolarian-based modern analogue datasets for the Southwest Pacific region.
• Studying the interaction of the Totten Glacier with the Southern Ocean through multiple glacial cycles.
• Taxonomic studies of radiolarian species distributions in Antarctic waters.

Strengths

• Data is linked to a specific, documented research voyage (IN2017_V01) with a publicly available post-cruise report.
• Taxonomic identifications follow established nomenclatures from Lazarus et al. (2015) and were cross-referenced with WoRMS and radiolaria.org.
• Sample processing followed a published method (Cortese and Prebble, 2015) for consistency.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
