Water bottle samples from 44 stations in a Florida study area provide counts and biochemical analysis of the harmful algal bloom species Karenia brevis. The dataset includes Coulter counts for the 14 to 28 um size class and, at six stations, per-cell measurements of lipid, free amino acid, and protein content. Data was collected during a November 1998 research cruise and analyzed by NOAA NCEI.
Use Cases
- Correlate cell counts in the 14-28 um size class with per-cell lipid content to study bloom energy reserves.
- Analyze spatial variation in free amino acid and protein levels across six sampled stations.
- Compare Coulter counter counts with microscope counts from other researchers for methodological validation.
- Investigate relationships between cellular biochemistry (lipid, amino acid, protein) and environmental conditions inferred from station depth.
Strengths
- Samples from 44 distinct stations provide spatial coverage.
- Biochemical analyses (lipid, amino acid, protein) performed within two weeks of collection to preserve sample integrity.
Limitations
- Limited temporal coverage from a single cruise in November 1998.
- Biochemical analysis (lipid, amino acid, protein) only available for six of the 44 stations.
- Unknown sample size (row count) and specific column schema.
