METEOR Cruise CTD/STD Data from Indian and Southern Oceans

High-resolution CTD/STD data from the METEOR research cruise spans the Indian Ocean and Southern Ocean from November 19, 1980, to March 7, 1981. The dataset was processed by the National Oceanographic Data Center (NODC) into the standard F022 format, providing detailed profiles of oceanographic parameters. It captures continuous measurements of temperature, salinity, density, and other variables at fine depth intervals.

Use Cases

• Analyzing vertical profiles of temperature and salinity to study water mass structure in the Indian Ocean.
• Calculating density (sigma-t) from the provided measurements to investigate ocean stratification and mixing processes.
• Correlating environmental data, such as meteorological conditions, with subsurface oceanographic observations from specific stations.
• Using the precise position, date, and time data to map the spatial and temporal distribution of ocean properties during the cruise.

Strengths

• Data is processed to the NODC standard High-Resolution CTD/STD (F022) format, ensuring a consistent and documented structure.
• Provides high-resolution, near-continuous profiles with measurements reported at depth intervals as fine as 1 meter.
• Covers a specific, well-documented cruise (METEOR) over a 3.5-month period from 1980-11-19 to 1981-03-07.

Limitations

• Critical metadata such as row count, file size, and specific column names are unavailable across all platforms.
• License information is not provided, which may restrict clear understanding of usage rights.
• The dataset's presence on NASA EarthData lacks any descriptive metadata, limiting cross-platform synthesis.
