High-Resolution CTD/STD Profiles from Pacific Ocean Cruises (1967-1968)

Data from 1967-01-25 to 1968-04-18 contains high-resolution conductivity-temperature-depth (CTD) and salinity-temperature-depth (STD) profiles from seven research vessels in the North and South Pacific Ocean. The National Oceanographic Data Center (NODC) processed the data to its standard F022 format, providing near-continuous measurements of temperature, salinity, density, and other parameters at fine depth intervals. This dataset represents a snapshot of mid-20th century oceanographic conditions.

Use Cases

• Analyzing vertical profiles of temperature and salinity from specific stations for water mass identification.
• Calculating historical density (sigma-t) distributions to study ocean stratification and circulation patterns.
• Correlating cruise-reported environmental data (e.g., meteorological conditions) with subsurface measurements.
• Examining spatial and temporal variability of dissolved oxygen or transmissivity across the Pacific basin.

Strengths

• Data is processed to a standard NODC format (F022), ensuring a consistent structure.
• Provides high-resolution, near-continuous profiles with depth intervals as fine as 1 meter.
• Includes metadata for each station: cruise information, instrument details, position, date, time, and sampling interval.

Limitations

• Specific row counts, column names, and dataset size are unknown from the provided sources.
• Data values may be subject to averaging, filtering, or interpolation, affecting raw measurement fidelity.
• The license information is not provided, which restricts clarity on reuse permissions.
