NOAA NCEI CTD/STD Profiles from R/V Wecoma in the North Pacific

NOAA NCEI provides oceanographic profile data collected from the R/V Wecoma in the North Pacific Ocean during a cruise from August 1-4, 1981. The dataset contains high-resolution vertical profiles of temperature, salinity, density, and possibly dissolved oxygen or transmissivity, processed to the NODC F022 standard format. Measurements were taken using conductivity-temperature-depth (CTD) and salinity-temperature-depth (STD) instruments, with data reported at depth intervals as fine as 1 meter.

Use Cases

• Analyzing vertical profiles of temperature and salinity for water mass identification.
• Studying ocean density stratification using computed sigma-t values.
• Investigating historical oceanographic conditions during a specific August 1981 cruise.
• Correlating environmental parameters like dissolved oxygen with depth and location.

Strengths

• Data is processed to a documented standard format (NODC F022), ensuring consistency.
• Provides high-resolution vertical profiles with sampling intervals as fine as 1 meter.
• Includes cruise metadata such as station position, date, time, and environmental conditions.

Limitations

• Specific column names, row counts, and file size are not provided by any source.
• The temporal coverage is limited to a single four-day cruise in August 1981.
• Conflicting 'last updated' dates exist between platforms (2026-03-05 on Data.gov vs. 1981-08-04 on NASA Earthdata).
