Indonesian Throughflow Nutrient Fluxes in Lombok, Ombai, and Timor Passages, 2004-2006

Depth-resolved and cross-strait integrated nitrate, phosphate, and silicate fluxes for the 2004-2006 INSTANT field program period. The dataset, provided by the Australian Ocean Data Network, contains traditional and effective flux calculations for three key straits in the Indian Ocean. Negative fluxes indicate westward transport towards the Indian Ocean.

Use Cases

• Modeling ocean biogeochemistry based on depth-resolved nutrient fluxes.
• Analyzing inter-strait variability in nutrient transport based on data from Lombok, Ombai, and Timor passages.
• Studying temporal trends in the Indonesian Throughflow based on the 2004-2006 observation period.
• Validating ocean circulation models based on traditional versus effective flux calculations.

Strengths

• Data covers a specific 3-year time period (2004-2006) from a named field program (INSTANT).
• Provides flux calculations for three distinct geographic straits (Lombok, Ombai, Timor).
• Includes both traditional and effective flux calculations for comparative analysis.
• Fluxes are depth-resolved and cross-strait integrated, offering detailed spatial structure.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic/temporal bias inherent to the INSTANT program's 2004-2006 sampling.
