Key Points

This study aims to explore the changes in bottom water oxygenation over the last 30,000 years.
Analyzed environmental magnetic parameters to assess bottom water conditions.
Developed a chronology to date the changes over millennia.
Utilized proxies to measure historical oxygen levels in bottom waters.
Findings indicate significant fluctuations in bottom water oxygenation since 30,000 years ago.
The data suggests a correlation between environmental changes and periods of low oxygenation.

Implication

Dataset reports bottom water oxygenation proxies in the northern South China Sea, indicating environmental changes over millennia.

Abstract

This dataset is relative to the manuscritp "Biogenic Magnetite Indicating Millennial-scale Evolution of Bottom Water Oxygenation Since about 30 ka", including the chronology, environmental magnetic parameters and bottom water oxygenation proxies from the northern South China Sea since about 30 ka.
