82 measurements of total inorganic carbon and 59 ammonium concentration readings were collected from the North Atlantic water column during a 1989 research cruise. Scientists Peter Williams and Graham Savidge gathered this data aboard the RRS Discovery 182 for the Biogeochemical Ocean Flux Study (BOFS). The cruise operated from May 10 to June 5, 1989.
Use Cases
- Analyze the relationship between total inorganic carbon (TCO2) and ammonium (NH4) concentrations across sampled locations.
- Model spatial distributions of dissolved carbon and ammonium within the +46N to +60N, +18W to +21W study region.
- Establish a 1989 baseline for carbon concentration in the North Atlantic water column for historical climate comparisons.
- Study nutrient (ammonium) availability and its potential coupling with carbon cycle dynamics during the late spring period.
Strengths
- Provides 82 precise TCO2 measurements via coulometry.
- Includes 59 concurrent NH4 measurements via colorimetric autoanalysis.
- Clear spatial (+46N to +60N, +18W to +21W) and temporal (May 10 to June 5, 1989) boundaries.
Limitations
- Small sample size with only 141 total data points.
- Data is over 30 years old, limiting analysis of current ocean conditions.
- Geographic coverage is restricted to a specific transect in the North Atlantic.
