Subduction ARI Oceanographic Data from NE Atlantic Cruises 1991-1994

Four oceanographic surveys collected in the Eastern North Atlantic Ocean during Spring 1991, Winter 1992, Winter 1993, and Spring 1994. This dataset contains temperature, salinity, pressure, and Acoustic Doppler Current Profiler (ADCP) data from CTD and current meter casts, mapped onto specific potential density surfaces. It was produced by the NOAA National Centers for Environmental Information as part of the Subduction Accelerated Research Initiative.

Use Cases

• Analyzing spatial variability of temperature and salinity fields in active frontal regions.
• Studying the formation and evolution of subducting water masses tagged by bobbers.
• Mapping current profiles (ADCP) on potential density surfaces of 26.5 and 26.7 kg/m^3.
• Investigating mesoscale oceanographic variability using data collected in 'star' survey patterns.
• Examining cruise navigation and engineering data from the Seasoar instrument.

Strengths

• Data spans four distinct seasonal cruises over a multi-year period from 1991 to 1994.
• Includes objectively mapped data on three specific potential density surfaces (26.5, 26.7, 26.9 kg/m^3).
• Contains multiple data types: 1- and 3-second CTD, navigation, ADCP, and engineering records.

Limitations

• Exact row count, file size, and complete column list are not provided by any source.
• Conflicting last updated dates exist between platforms (1993-06 14 and 2026-04-01).
• Original data delivery method (CD-ROM with color figures) may pose access challenges.
