Water bottle samples collected from 14 stations in Florida during a November 1998 cruise provide counts and biochemical analysis of the harmful algae Karenia brevis. Coulter counts for the 14-28 um size class were determined, and isolated algae pellets were analyzed for total lipid, neutral lipid, free amino acids, protein, RNA, chlorophyll, and nitrate. The dataset was produced by Kamykowski's NCSU laboratory for NOAA NCEI.
Use Cases
- Analyze relationships between Karenia brevis cell counts (14-28 um size class) and biochemical concentrations like total lipid or protein.
- Model spatial distribution of algal blooms using station location data and associated biochemical markers such as chlorophyll and nitrate.
- Study algal physiology by correlating free amino acids or RNA content with cell counts from specific water depths.
- Compare Coulter counter counts with microscope counts for calibration and methodological validation.
Strengths
- Data includes biochemical analysis of 5 specific components: total lipid, neutral lipid, free amino acids, protein, and RNA.
- Samples were collected from 14 distinct stations, providing spatial coverage.
- Analyses were performed within two weeks of collection, minimizing degradation.
Limitations
- Sample size is limited to a single cruise over 4 days in November 1998.
- Geographic coverage is restricted to one study area in Florida.
- No row count, column names, or sample data are provided, limiting reproducibility.
