North Atlantic Oceanographic Station and Bathythermograph Data 1975-1986

Data from 1975 to 1986 contains physical and chemical oceanographic measurements collected via Nansen casts, CTD/STD recorders, and bathythermograph instruments from platforms like SAXON STAR in the North Atlantic Ocean and other seas. The dataset, processed by NODC into standard formats C100, C116, and C128, includes temperature, salinity, dissolved oxygen, nutrients, pH, and derived parameters like density and sound velocity. It was collected by the Deutsches Hydrographische Institut.

Use Cases

• Analyzing vertical profiles of temperature and salinity (C100 format) to study water mass structure.
• Investigating nutrient distributions (phosphate, silicate, nitrate) for biogeochemical cycle research.
• Using derived parameters like sigma-t density and dynamic depth anomaly for ocean dynamic calculations.
• Examining bathythermograph (XBT/MBT) temperature-depth profiles (C116/C128 formats) for thermal structure analysis.
• Correlating meteorological conditions (air temperature, pressure, wind) reported at stations with ocean surface states.

Strengths

• Covers an 11-year time range from April 1975 to March 1986.
• Includes data interpolated to standard depth levels for consistent comparison.
• Contains multiple measurement types from bottle casts (majority) and electronic CTD/STD recorders.

Limitations

• Key metadata like row count, column names, and exact size are unknown across all sources.
• A small conflict exists on the 'last updated' date: one source lists 1986-03-12, another lists 2026-04-01.
• License information is not provided.
