Oceanographic profiles from the research vessels ATLANTIS I and ATLANTIS II contain measurements of temperature, salinity, pH, and concentrations of oxygen, nutrients, and chlorophyll a. Data collection spans from 1931 to 1997, with this specific accession covering 1950 to 1974. The Woods Hole Oceanographic Institute submitted the data to NOAA's National Centers for Environmental Information.
Use Cases
- Analyze long-term trends in temperature and salinity profiles to study Atlantic Ocean warming or freshening.
- Model relationships between nutrient concentrations (phosphate, nitrate, silicate) and chlorophyll a levels for primary production studies.
- Correlate oxygen concentration profiles with temperature and salinity data to assess historical ocean ventilation.
- Use pH and nutrient time-series data to investigate pre-industrial ocean acidification and biogeochemical cycles.
Strengths
- Multi-decade temporal coverage from 1931 to 1997, providing a long-term historical baseline.
- Includes a diverse set of chemical and physical measurements per profile (e.g., temperature, salinity, multiple nutrients, chlorophyll).
- Data originates from two dedicated research vessels, ensuring consistent collection methodology over time.
Limitations
- Data recency is limited, with the last update recorded in 1974 for this accession, missing recent decades.
- Spatial coverage is focused on the North Atlantic and coastal North Atlantic, limiting global applicability.
- Unknown sample size and row count prevent assessment of data density and statistical power.
