Mid-Pacific Ocean Temperature and Salinity Profiles from 1968 Cruise

Northeast Pacific Ocean data from the RV Thomas G. Thompson's 1968 TT-027 cruise, collected for the O.N.R. Study of the Mid-Pacific Transition Zone. The dataset contains high-resolution vertical profiles of temperature, salinity, and other parameters, processed by the National Oceanographic Data Center (NODC) into the standard F022 format. It represents a month-long survey from April to May 1968.

Use Cases

• Analyzing vertical temperature and salinity structure in the Mid-Pacific Transition Zone.
• Studying historical oceanographic conditions for climate change baselines using depth, temperature, and salinity columns.
• Calibrating or validating ocean models with high-resolution in-situ profile data.
• Investigating cruise-specific metadata, station positions, and sampling intervals for research methodology studies.

Strengths

• Data is processed to a known, documented standard (NODC High-Resolution CTD/STD F022 format).
• Provides high-resolution profiles with potential sampling at depth intervals as fine as 1 meter.
• Includes contextual data such as cruise information, position, date, time, and environmental conditions for each station.

Limitations

• Exact row count, file size, and complete column list are unknown.
• Conflicting last update dates exist between platforms (1968-05 02 vs. 2026-03-05), indicating potential metadata inconsistency.
• License information is not provided.
