Radiolarian Abundance in the Equatorial Pacific from 1992 JGOFS Study

111 radiolarian species were enumerated from plankton samples collected during four 1992 cruises along 140°W longitude. The Equatorial Pacific Process Study (EQPAC) was conducted by the Joint Global Ocean Flux Study (JGOFS) to investigate ocean biogeochemistry. Abundance data is provided in counts per cubic meter, including total radiolarian abundance.

Use Cases

• Modeling plankton community dynamics based on species abundance data across latitudes.
• Investigating seasonal changes in radiolarian populations based on data from four distinct cruises.
• Calibrating paleoceanographic proxies using modern radiolarian abundance and distribution patterns.
• Studying equatorial Pacific biogeography based on sampling from 12°N to 17°S latitude.

Strengths

• Species-level resolution with 111 distinct radiolarian taxa enumerated.
• Spatial coverage spans from 12°N to 17°S latitude along a consistent 140°W longitude transect.
• Temporal coverage includes four distinct cruises conducted between February and October 1992.

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.
