High-Resolution CTD/STD Oceanographic Data from ACONA Cruises

October 1977 to August 1979 data contains high-resolution conductivity-temperature-depth and salinity-temperature-depth profiles from the ACONA research vessel. The dataset covers the Bering Sea, Coastal Waters of Southeast Alaska and British Columbia, Gulf of Alaska, and North Pacific Ocean. Data was processed by the National Oceanographic Data Center to its standard F022 format.

Use Cases

• Analyzing vertical profiles of temperature, salinity, and density (sigma-t) for water column structure.
• Correlating cruise-specific station data, including position, date, and time, with environmental conditions.
• Studying dissolved oxygen or light transmissivity variations at specified depth or pressure levels.
• Examining near-continuous, fine-scale (as fine as 1-meter intervals) oceanographic measurements.

Strengths

• Data is processed to a recognized standard format (NODC F022), ensuring consistency.
• Provides high-resolution profiles with depth intervals as fine as 1 meter.
• Covers a multi-year time range (1977-1979) across several key North Pacific regions.

Limitations

• Key technical details like row count, column names, and file size are unavailable from all sources.
• Data values may be subject to averaging, filtering, or interpolation, as noted in the format description.
• The NASA Earthdata entry lacks a descriptive summary, limiting cross-platform synthesis.
