OMEX 1: Oceanographic Campaign Data from the N.E. Atlantic (1993-1995)

NCEI Accession 0000172 contains physical, biological, and current data collected during the OMEX 1 project in the Northeast Atlantic Ocean. The dataset includes measurements from CTD, XBT, ADCP, bottle casts, and net casts from April 1993 to December 1995. Parameters likely include temperature, salinity, sediment porosity, zooplankton species counts, and current speed and direction.

Use Cases

• Modeling shelf-sea nutrient cycling based on CTD-derived temperature and salinity profiles.
• Analyzing zooplankton community structure based on species count data from net casts.
• Studying sediment transport dynamics using ADCP current speed and direction measurements.
• Investigating water column structure and frontal systems using XBT temperature profiles.

Strengths

• Data collected over a multi-year campaign (April 1993 to December 1995), providing temporal context.
• Multi-instrument approach (CTD, XBT, ADCP, bottle casts, net casts) captures diverse oceanographic parameters.
• Dataset is hosted by authoritative organizations (NOAA, NASA Earthdata), indicating institutional provenance.

Limitations

• Column names and exact data structure are not provided in any source, complicating direct analysis.
• Sources conflict on the last updated date (1995-12-01 vs. 2026-04-01), creating uncertainty about metadata maintenance.
• Key metadata such as row count, file size, and specific license are uniformly absent.
