High-Resolution CTD/STD Profiles from RV Alpha Helix

High-resolution CTD/STD data from the RV Alpha Helix in the Gulf of Alaska from 1986-12-15 to 1986-12-19. The data, processed to the NODC F022 standard, likely contains nearly continuous profiles of temperature, salinity, density, and possibly dissolved oxygen or transmissivity at depth intervals as fine as 1 meter. Cruise information, position, date, time, and environmental conditions are reported for each station.

Use Cases

• Analyzing vertical profiles of temperature and salinity to study water column structure.
• Investigating relationships between density (sigma-t) and other measured parameters.
• Using station position and time data to map oceanographic conditions during the cruise.
• Examining potential dissolved oxygen or transmissivity data for insights into water quality.

Strengths

• Data is processed to a recognized standard format (NODC High-Resolution CTD/STD F022).
• Provides high-resolution profiles with potential depth intervals as fine as 1 meter.
• Covers a specific 5-day research cruise in the Gulf of Alaska.

Limitations

• Key metadata such as row count, specific column names, and license are unknown.
• Data is from a single, short cruise in 1986, limiting temporal and spatial scope.
• There is a conflict in the 'last updated' metadata between platforms (2026 vs. 1986).
