JGOFS EQPAC: Water-Column Carbohydrate Percentages from 1992 Cruises

Carbohydrate percentages in water-column samples collected during the 1992 Joint Global Ocean Flux Study (JGOFS) Equatorial Pacific Process Study. Data includes measurements from floating sediment traps and plankton tows for ten specific carbohydrates, along with particulate organic carbon, inorganic carbon, nitrogen, and total particulate matter flux. The study involved four primary cruises along 140°W longitude from February to October 1992.

Use Cases

• Modeling marine carbon cycling based on carbohydrate composition and particulate organic carbon measurements.
• Analyzing spatial and temporal variability in organic matter based on data from stations spanning 12°N to 17°S.
• Correlating carbohydrate signatures with total particulate flux data from sediment trap samples.
• Studying the relationship between specific sugars (e.g., glucose, galactose) and broader biogeochemical parameters.

Strengths

• Includes measurements for ten specific carbohydrates and four key biogeochemical parameters.
• Data collected during four dedicated cruises across multiple seasons in 1992.
• Spatial coverage spans from 12°N to 17°S latitude along 140°W longitude.

Limitations

• Last updated 1992-09-18 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
