North Atlantic Chlorophyll and Primary Productivity Data from 1988 Expedition

July-September 1988 data from NOAA's Global Change Expedition aboard the Mt. Mitchell, covering the North Atlantic across four legs. The dataset includes parameters like salinity, temperature, chlorophyll a, total pigment, and primary productivity measurements from thirty-four stations. Data was submitted by Dr. D.W. Frazel of RSMAS, University of Miami, and processed by OCL in January 1995.

Use Cases

• Analyze the relationship between chlorophyll a concentration and primary productivity measurements across the sampled stations.
• Model spatial and temporal variations in salinity and temperature against total pigment levels.
• Establish a 1988 baseline for North Atlantic phytoplankton biomass using the chlorophyll a data for comparison with modern studies.
• Investigate nutrient cycling by correlating primary productivity data with other expedition parameters from the related NCEI Accession #9000187.

Strengths

• Data collected from thirty-four distinct sampling stations.
• Includes five key oceanographic parameters: salinity, temperature, chlorophyll a, total pigment, and primary productivity.
• Covers a defined temporal period from July to September 1988.

Limitations

• Sample size is limited to a single expedition in 1988, providing only a seasonal snapshot.
• Data is over 35 years old, limiting its relevance for contemporary climate studies without recent comparisons.
• The related nutrient data is stored in a separate accession (#9000187), requiring a join for complete analysis.
