NCEI Accession 0000445 contains bottle-collected oceanographic profiles from the R/V CHAIN in the North Atlantic and other locations. The dataset includes measurements of temperature, salinity, pH, primary production rates, and concentrations of oxygen, nutrients, and chlorophyll a. Data were submitted by the Woods Hole Oceanographic Institution and cover the period from December 1958 to April 1968.
Use Cases
- Model historical primary production rates using chlorophyll a and nutrient concentration profiles.
- Analyze decadal water mass characteristics from temperature and salinity profiles.
- Study nutrient stoichiometry relationships using concurrent phosphate, nitrate, nitrite, silicate, and ammonia measurements.
- Correlate oxygen concentration profiles with biological production data.
- Investigate seasonal or interannual variability in particulate organic carbon across the sampling period.
Strengths
- Nearly 10 years of temporal coverage from 1958 to 1968.
- Multiple concurrent chemical and physical measurements per profile, including over 10 distinct variables.
Limitations
- Data is over 50 years old and may not reflect current ocean conditions.
- Specific sample size (row count) and spatial resolution are unknown from the description.
- Data collection was limited to specific cruise tracks, not a continuous spatial grid.
