Columbus Iselin CTD/STD Profiles from Arabian Sea and North Atlantic

NOAA_NCEI provides high-resolution CTD/STD data from the R/V Columbus Iselin across the Arabian Sea, Indian Ocean, and North Atlantic Ocean. The dataset, processed to the NODC F022 standard format, contains nearly continuous vertical profiles of ocean parameters. Measurements were collected between March 1979 and November 1981.

Use Cases

• Analyzing vertical temperature and salinity gradients to study water mass distribution.
• Calculating density (sigma-t) profiles for physical oceanography and circulation modeling.
• Investigating dissolved oxygen or transmissivity data for biogeochemical studies.
• Correlating station data (position, date, time) with meteorological conditions for air-sea interaction research.

Strengths

• Data is high-resolution, with profiles potentially reported at depth intervals as fine as 1 meter.
• Coverage spans multiple major ocean basins (Arabian Sea, Indian Ocean, North Atlantic) over a 2.5-year period.
• Data is processed and standardized to the authoritative NODC F022 format.

Limitations

• Specific column names, row counts, and file size are not provided by any source.
• The license and author information are unknown, restricting clarity on reuse permissions.
• A conflict exists in last updated metadata: one source reports 2026-03 05, while another indicates the data collection end date of 1981-11-06.
