IDOE/ISOS/FDRAKE: Oceanographic Station and Temperature Profile Data

Oceanographic Station Data and temperature profiles were collected from bottle and XBT casts from the ALMIRANTE IRIZAR and other platforms from 18 January 1975 to 06 November 1982. Data were collected by the Secretaria De Marina; Servicio De Hidrografia Naval as part of the International Decade of Ocean Exploration / International Ocean Studies / First Dynamic Response and Kinematics Experiment in the Drake Passage. The dataset contains physical-chemical oceanographic data recorded at discrete depth levels, with interpolated values for standard depths, and includes meteorological and auxiliary observations.

Use Cases

• Analyzing temperature and salinity profiles in the Drake Passage based on bottle and XBT casts.
• Studying nutrient distributions (phosphate, silicate, nitrate) from discrete water samples.
• Investigating relationships between meteorological conditions (wind, waves) and oceanographic parameters at the time of cast.
• Calculating derived oceanographic properties like density (sigma-t) and sound velocity from measured parameters.
• Examining water transparency and color trends using Secchi disk depth and Forel-Ule scale auxiliary data.

Strengths

• Contains data from a specific, multi-year international oceanographic experiment (IDOE/ISOS/FDRAKE) from 1975-1982.
• Includes interpolated values to a set of standard depth levels, facilitating comparative analysis.
• Processed to two standardized NODC formats (Oceanographic Station Data and UBT), ensuring consistency.

Limitations

• Column names and exact data structure are unknown from the provided metadata.
• Conflicting last updated dates exist between sources (1982-11-06 and 2026-04-01), indicating potential metadata inconsistency.
• Size and row counts are unknown, limiting assessment of dataset scale.
