Coastal CTD Profiles from the Slope Undercurrent Study 1977-1978

CTD data from nine R/V WECOMA cruises along the northwest Pacific coastline, collected by Adriana Huyer of Oregon State University for the Slope Undercurrent Study. The dataset provides high-resolution vertical profiles of temperature, salinity, density, and other oceanographic parameters. Data is processed to the NODC standard High-Resolution CTD/STD (F022) format.

Use Cases

• Analyzing vertical structure of temperature and salinity for water mass identification.
• Studying coastal current dynamics and the Slope Undercurrent using density (sigma-t) profiles.
• Investigating dissolved oxygen or water clarity trends using optional transmissivity data.
• Calibrating regional ocean models with high-resolution, quality-controlled in-situ measurements.

Strengths

• Data is processed to a recognized standard (NODC F022 format) ensuring consistency.
• Provides high-resolution profiles with sampling intervals as fine as 1 meter.
• Covers a multi-cruise study over 14 months, offering temporal context for seasonal changes.

Limitations

• Specific column names, total row count, and exact file size are not provided by any source.
• Sources conflict on the precise start date (1977-07-27 vs 1977-07-31).
• License information is not available, restricting clarity on reuse terms.
