Oceanographic CTD Data from Chinese Research Vessels (1992-1993)

NOAA NCEI Accession 9400159 contains depth, temperature, salinity, and oxygen data collected for the World Ocean Circulation Experiment. The Chinese National Oceanographic Data Center provided the data, which was gathered from three research vessels between November 1992 and December 1993. Data submission was on two tapes and four diskettes.

Use Cases

• Analyze vertical profiles of temperature and salinity (CTD data) to study water mass structure.
• Correlate oxygen concentration with depth and temperature to assess biological activity and ocean ventilation.
• Examine temporal changes in oceanographic parameters from November 1992 to December 1993.
• Compare data collected from different platforms (XIANG YANG HONG 09, SHI YAN 3, XIANG YANG HONG 05) for instrument or spatial consistency.

Strengths

• Data spans a 13-month time range from November 1992 to December 1993.
• Includes four core oceanographic parameters: depth, temperature, salinity, and oxygen.
• Data contributed by a national data center (Chinese National Oceanographic Data Center) for an international experiment (WOCE).

Limitations

• Sample size and spatial coverage are unknown, limiting statistical assessment.
• Data is from 1992-1993 and may not reflect current ocean conditions.
• Original submission on physical media (tapes, diskettes) may pose accessibility challenges.
