Bioavailable Organic Particles in the Pacific Ocean from 2022 Cruise

From June 9 to July 25, 2022, field sampling was conducted along the 155°E transect in the Kuroshio-Oyashio Extension during the KK2202 cruise aboard the R/V Tan Kah Kee. The dataset includes total particulate amino acid concentrations, chlorophyll a concentrations, and apparent oxygen utilization values. It was authored by Xiaoxia Chen and is available under a CC-BY-4.0 license.

Use Cases

• Modeling carbon export efficiency based on particulate amino acid concentrations.
• Investigating the relationship between chlorophyll a and bioavailable organic particle size fractions.
• Analyzing apparent oxygen utilization as a proxy for remineralization processes.
• Studying the compositional variability of amino acids relative to total particulate amino acids.

Strengths

• Data is size-fractionated into 1–51 μm and > 51 μm particles, allowing for analysis of particle size distribution.
• Includes molar percentages for 20 individual amino acids, providing detailed compositional data.
• Covers a specific transect (155°E) in the Kuroshio-Oyashio Extension during a defined cruise period.

Limitations

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