NCEI 0157469: CTD and Bottle Oceanographic Profiles from the North Atlantic

NCEI Accession 0157469 contains chemical, physical, and profile data from the ATLANTIS research vessel in the North Atlantic Ocean. The dataset includes measurements of dissolved oxygen, nitrate, nitrite, phosphate, silicate, salinity, and water temperature collected between January 18 and 31, 2006. Data were gathered by Terrence M. Joyce of the Woods Hole Oceanographic Institution using CTD and bottle instruments during cruise AT013/CMDL2.

Use Cases

• Analyzing vertical profiles of water temperature and salinity (theta) to study ocean stratification.
• Investigating nutrient distributions (nitrate, phosphate, silicate) to assess marine productivity.
• Calibrating satellite-derived sea surface salinity data with in-situ discrete measurements.
• Studying dissolved oxygen levels in relation to hydrostatic pressure and depth.

Strengths

• Data collection uses established oceanographic instruments (CTD and bottle), suggesting methodological rigor.
• Provides a specific two-week temporal snapshot (2006-01-18 to 2006-01-31) from a known research vessel (ATLANTIS).
• Includes multiple related cruise identifiers (AT013 and CMDL2), aiding in provenance tracking.
• Hosted by authoritative institutions (NOAA, NASA Earthdata), indicating formal curation.

Limitations

• Key metadata is missing or conflicting: row count, file size, and specific column names are unknown across all sources.
• The license for use is not specified in any provided source description.
• One platform lists a last updated date far in the future (2026-03-06), creating a conflict with the actual data collection date and casting doubt on metadata maintenance.
