High-Resolution Gulf of Alaska CTD/STD Profiles from 1979

Oceanographic profiles from the ACONA cruise in the Gulf of Alaska, collected on July 29-30, 1979. Data is processed to the NODC standard High-Resolution CTD/STD format, containing near-continuous measurements of temperature, salinity, and density. The dataset is managed and distributed by NOAA's National Centers for Environmental Information.

Use Cases

• Analyzing vertical profiles of temperature and salinity for water mass identification.
• Calculating density (sigma-t) from measured parameters to study ocean stratification.
• Correlating station-specific metadata (position, time) with environmental conditions.
• Examining high-resolution data reported at intervals as fine as 1 meter for detailed structure.

Strengths

• Data is processed to a recognized standard format (NODC F022) ensuring consistency.
• Provides high-resolution profiles with potential sampling at 1-meter depth intervals.
• Includes contextual metadata for each station, such as cruise information, position, date, and time.

Limitations

• Exact row count, column names, and file size are unknown from available metadata.
• Data coverage is limited to a brief two-day period in July 1979.
• Conflicting freshness information exists between a 2026 platform update date and a 1979 data collection date.
