Cruise Piquero Leg 7: High-Resolution Ocean CTD/STD Profiles

June 4-21, 1969, oceanographic data from the R/V Thomas Washington in the Southeast Pacific. The dataset contains high-resolution conductivity-temperature-depth (CTD) and salinity-temperature-depth (STD) profiles, processed to a standard format with data smoothed at one-meter intervals. Each station record includes position, time, and may include environmental data like meteorological conditions.

Use Cases

• Analyzing vertical profiles of temperature and salinity for water mass identification.
• Studying oceanographic conditions during a specific 1969 cruise based on station position and time data.
• Calibrating or validating ocean models using historical high-resolution in-situ measurements.
• Investigating relationships between surface conditions (meteorological data) and subsurface ocean structure.

Strengths

• Data is processed to a documented standard format (NODC F022), ensuring consistency.
• Provides high-resolution vertical profiles with data reported at one-meter intervals.
• Contains multi-parameter measurements including temperature, salinity, density, and potentially dissolved oxygen.

Limitations

• Critical metadata conflicts: one source lists a last update in 2026, another in 1969, casting doubt on provenance.
• Specific column names, row counts, and file size are unknown across all platforms.
• License and author information is not provided.
