Seasonal Geogenic Phosphorus, DOM, and Microbial Metagenomics in Aquifers

Seasonal oxidant influx modifies redox conditions, transforming high-molecular-weight humic substances into low-molecular-weight polar compounds and shifting microbial phosphorus metabolism pathways. This dataset integrates field monitoring, molecular dissolved organic matter characterization, and metagenomic analyses to elucidate the coupling between geogenic phosphorus, phosphorus-containing DOM, and microbial functional pathways in alluvial-lacustrine aquifers. It links dissolved inorganic phosphorus fluctuations to a degradation gradient of P-containing DOM and concurrent adjustments in microbial metabolism.

Use Cases

• Modeling seasonal dissolved inorganic phosphorus fluctuations based on degradation gradients of phosphorus-containing DOM.
• Analyzing shifts in microbial phosphorus metabolism pathways (e.g., dephosphorylation vs. C–P bond cleavage) in response to redox condition changes.
• Investigating the transformation of high-molecular-weight humic substances into low-molecular-weight polar compounds driven by seasonal oxidant influx.
• Correlating metagenomic functional data with molecular DOM characterization to understand microbial drivers of geogenic phosphorus dynamics.

Strengths

• Dataset is large, with a file size of approximately 121.6 MB, suggesting substantial underlying data.
• Data is openly available under a CC-BY-4.0 license, facilitating reuse and redistribution.
• Integrates multiple analytical methods: seasonal field monitoring, molecular DOM characterization, and metagenomic analyses.

Limitations

• Column names and the exact row count are not provided, limiting understanding of the data's structure and scale.
• The dataset's temporal coverage (e.g., specific years or seasons) is not explicitly stated.
• The geographic location of the studied alluvial-lacustrine aquifers is unspecified.
