Ocean Temperature and Nutrient Profiles from Indian and North Atlantic Oceans, 1966-1980

Indian and North Atlantic Ocean bottle cast data collected from multiple research vessels between July 1966 and June 1980. The dataset includes profiles for temperature, salinity, pH, and concentrations of nutrients like phosphate, nitrate, and silicate. Data were submitted by the Australian Bureau of Meteorology.

Use Cases

• Model historical ocean temperature and salinity trends based on profile data.
• Analyze nutrient concentration distributions (phosphate, nitrate, silicate) for biogeochemical studies.
• Study dissolved oxygen and chlorophyll a levels for marine ecosystem health assessment.
• Correlate multiple chemical and physical parameters for water mass characterization.

Strengths

• Covers a 14-year time range from 1966 to 1980.
• Includes multiple measured parameters: temperature, salinity, pH, and several nutrient concentrations.
• Geographic scope spans the Indian Ocean and North Atlantic Ocean (west of 40W).

Limitations

• Last updated 1980-06-05 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
