Pacific Ocean Temperature and Salinity Profiles from IDOE/NORPAX Project

CTD and STD instrument profiles provide temperature, salinity, density, and other oceanographic measurements from the Pacific Ocean. Data were collected from multiple vessels, including the GYRE, as part of the International Decade of Ocean Exploration North Pacific Experiment (IDOE/NORPAX) project. The dataset was submitted by Scripps Institution of Oceanography and processed by the National Oceanographic Data Center into the high-resolution F022 standard format.

Use Cases

• Analyzing vertical ocean structure by plotting temperature and salinity against depth or pressure levels.
• Calculating derived water properties like density (sigma-t) from the core temperature and salinity/conductivity measurements.
• Studying spatial and temporal patterns by grouping profiles using cruise, station, position, date, and time metadata.
• Correlating subsurface conditions with surface observations using reported meteorological and sea surface data.
• Assessing data quality or adding context by referencing the available text comment records for each cast.

Strengths

• Data provides high-resolution vertical profiles, with measurements potentially reported at intervals as fine as 1 meter.
• Collection was part of a coordinated international research program (IDOE/NORPAX), ensuring standardized collection methods.
• Data is structured according to a documented NODC standard format (F022), which includes cruise, instrument, position, and environmental metadata.

Limitations

• Key quantitative metrics like row count, file size, and specific column names are not provided by any source.
• Sources conflict on the last update date, with one indicating 2026-03 06 and another indicating 1980-06-14.
• The license and author information are not specified, which may restrict certain uses.
