High-Resolution CTD/STD Ocean Profiles from R/V Wecoma in the North Pacific

High-resolution conductivity-temperature-depth (CTD) and salinity-temperature-depth (STD) data were collected during a cruise of the R/V Wecoma in the North Pacific Ocean. The dataset, processed by the National Oceanographic Data Center (NODC) to its F022 standard format, contains nearly continuous profiles of temperature, salinity, and other parameters from April 26 to May 7, 1981. It is provided by the National Oceanic and Atmospheric Administration.

Use Cases

• Analyzing vertical profiles of temperature and salinity to study water mass structure and ocean stratification.
• Calculating derived parameters like density (sigma-t) for physical oceanography and circulation modeling.
• Correlating in-situ oceanographic measurements with concurrent meteorological and sea surface condition data reported for each station.
• Investigating coastal ocean dynamics and biogeochemical processes off California using parameters like dissolved oxygen or transmissivity.

Strengths

• Data is processed to the NODC's standardized High-Resolution CTD/STD (F022) format, ensuring consistency and interoperability.
• Profiles provide high-resolution measurements, with data potentially reported at depth intervals as fine as 1 meter.
• Each station record includes cruise and instrument metadata, precise position, date, time, and sampling interval.

Limitations

• The exact column names, row count, and file size are not specified in the available metadata.
• Conflicts exist in the dataset title: one source specifies 'Coastal Waters of California', while another states the broader 'North Pacific Ocean'.
• The license governing data use is not declared.
