High-Resolution CTD Cast Profiles from the East China Sea

Conductivity-temperature-depth (CTD) casts collected during a joint U.S./China oceanographic program provide high-resolution vertical profiles of temperature, salinity, pressure, and dissolved oxygen in the East China Sea. Data were gathered from the vessel SCIENCE-1 over four days in July 1984 by the Woods Hole Oceanographic Institution. The profiles are processed to the NODC F022 standard format, reporting measurements at depth intervals as fine as one meter.

Use Cases

• Analyzing vertical temperature and salinity gradients for oceanographic research.
• Calculating water density (sigma-t) from temperature and salinity columns to study stratification.
• Correlating dissolved oxygen levels with depth and temperature to assess marine biogeochemistry.
• Using station position, date, and time data to reconstruct historical sampling conditions.

Strengths

• Data is processed to the NODC F022 high-resolution standard, capable of 1-meter depth intervals.
• Collected by the authoritative Woods Hole Oceanographic Institution during a formal international program.
• Covers multiple parameters including temperature, salinity, pressure, density, and dissolved oxygen.

Limitations

• The exact number of rows, columns, and file size is unknown across all sources.
• Data is from a single, brief cruise in July 1984, limiting temporal and spatial scope.
• Sources conflict on the last updated date, reporting both 1984-07-20 and 2026-04-01.
