The Challenger Deep in the Mariana Trench provides the geographic scope for this dataset. It contains full-depth water column analyses of dissolved organic phosphorus (DOP) and dissolved inorganic phosphorus (DIP), combined with results from high-pressure incubation experiments. The data was authored by Tianqiang Bao and last updated on May 11, 2026.
Use Cases
- Modeling phosphorus-alkaline phosphatase activity (P-APA) regulatory regimes based on DIP and DOP concentrations.
- Investigating microbial carbon demand in the hadal zone based on alkaline phosphatase activity (APA) data.
- Analyzing the link between active microbial communities and dissolved organic carbon using path analysis results.
- Studying the role of the SAR11 clade in deep-sea phosphorus acquisition based on its detection throughout the water column.
Strengths
- Includes data from the Challenger Deep, the deepest part of the ocean.
- Path analysis model explains 82.3% of variance in dissolved organic carbon and 75.4% of variance in DIP.
- Combines field observations from the water column with laboratory-based in-situ simulated high-pressure incubation experiments.
Limitations
- Dataset size is only 18.5 KB, indicating a very limited scope.
- Row count and column-level documentation are unknown, which limits suitability assessment.
- File format is DOCX, which may require conversion for analysis.
