Antarctic Krill Faecal Pellets: Iron Recycling and Export Measurements

Experimental data on Antarctic krill faecal pellets, including their physical characteristics and iron leaching rates. The dataset contains raw and analyzed measurements of pellet sinking rates, dimensions, density, dry weight, and iron leachate over a 12-hour period. It was published via the Australian Ocean Data Network and last updated in July 2026.

Use Cases

• Modeling iron export flux in the Southern Ocean based on faecal pellet sinking rates and iron content.
• Analyzing relationships between faecal pellet physical characteristics (length, diameter, density) and their sinking behavior.
• Estimating bioavailable iron release from krill faecal matter based on the 12-hour leaching experiment data.

Strengths

• Includes both raw and analyzed data for faecal pellet characteristics and iron leachate.
• Data covers multiple related measurements: sinking rates, pellet dimensions, density, dry weight, and iron leaching.
• Experimental design includes a controlled 12-hour iron leaching period under continuous seawater flow.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
