IODP 361-U1477 Paleoenvironmental Records and Microbial Paleontology Bibliometrics

IODP Expedition 361 Site U1477 provides a high-resolution oxygen isotope record for benthic foraminifera from 68 to 174 meters core depth. A complementary bibliometric dataset systematically catalogs academic literature on calcareous nannofossils, coccolithophores, and foraminifera from 1995 to 2025. The collection supports the establishment of geological time frameworks using key indicator species like Globigerinoides ruber and Emiliania huxleyi.

Use Cases

• Reconstructing past ocean temperatures and ice volume based on benthic foraminifera oxygen isotope (δ¹⁸O) records.
• Conducting literature reviews or meta-analyses in microbial paleontology using the systematic bibliometric dataset.
• Establishing geological age models and biostratigraphic correlations using absolute abundance statistics of key indicator species.
• Analyzing trends in scientific publication output for calcareous nannofossil and foraminifera research over a 30-year period.

Strengths

• Includes a high-resolution, physically measured paleoenvironmental proxy record (δ¹⁸O) from a defined sediment core interval.
• Bibliometric data covers a 30-year time range (1995-2025) from the Web of Science Core Collection, a major academic database.
• Dataset is openly licensed under CC-BY-4.0, facilitating reuse and citation.

Limitations

• Column names and a precise row count for the datasets are not provided, limiting understanding of data structure.
• The relationship and format linking the three described files (isotope data, bibliometrics, species statistics) is unclear.
• Geographic specificity for the paleoenvironmental core is limited to the IODP site identifier; precise location coordinates are not stated.
