Oceanographic Water Column Measurements from NOAA Ship Oceanographer, 1975-1976

Oxygen percent saturation and particulate organic carbon measurements were collected by NOAA Ship OCEANOGRAPHER from August 1975 to April 1976. The dataset is archived by NOAA's National Centers for Environmental Information under accession number 7800256. It captures in-situ water column data from a specific research cruise.

Use Cases

• Analyze temporal trends in oxygen_percent_saturation and particulate_organic_carbon over the cruise period.
• Correlate water column measurements with spatial coordinates (latitude, longitude) and depth to map property distributions.
• Use timestamp and location data to reconstruct the ship's track and sampling events for cruise validation.
• Calculate derived metrics like oxygen concentration from percent saturation given concurrent temperature and salinity data.

Strengths

• Data collected from a dedicated NOAA research vessel, ensuring controlled measurement protocols.
• Provides a continuous 7-month time series from a specific oceanic region.

Limitations

• Dataset is over 45 years old; sensor technology and calibration standards were less advanced.
• Specific sample size, geographic bounds, and data completeness are unknown from the metadata.
• Lacks documented quality flags or uncertainty estimates for the reported measurements.
