NOAA Oceanographer CTD/STD Profiles from the North Pacific Ocean

High-resolution CTD/STD data profiles were collected by NOAA Ship Oceanographer during a year-long cruise from August 1975 to August 1976. The dataset has been processed by the National Oceanographic Data Center into the standard F022 format. It provides nearly continuous vertical measurements of oceanographic parameters.

Use Cases

• Analyzing vertical profiles of temperature and salinity for oceanographic research.
• Studying historical density (sigma-t) variations in the North Pacific water column.
• Investigating potential relationships between dissolved oxygen levels and other ocean parameters.
• Correlating station-specific environmental data (e.g., meteorological conditions) with subsurface measurements.

Strengths

• Data provides high-resolution profiles with depth intervals as fine as 1 meter.
• Coverage spans a full year of observations from August 1975 to August 1976.
• Data is processed to a standardized NODC format (F022), ensuring consistency.

Limitations

• The exact number of rows, columns, and file size is unknown from provided sources.
• Sources conflict on the last updated date: one lists 2026-04-01, another lists 1976-08-31.
