Oceanographic Measurements from EXCELLENCE Expedition (1979-1980)

Oceanographic data collected by the NOAA vessel EXCELLENCE from February 1979 to March 1980. The dataset includes measurements of oxygen percent saturation and particulate organic carbon. Data was collected and archived by NOAA's National Centers for Environmental Information (NCEI).

Use Cases

• Analyze temporal trends in oxygen_percent_saturation to study ocean deoxygenation over the expedition period.
• Correlate particulate_organic_carbon measurements with other oceanographic variables to understand carbon export.
• Map the geospatial distribution of collected parameters to identify regional biogeochemical provinces.
• Use the time-series data to validate historical reconstructions of ocean water quality for the late 1970s.

Strengths

• Data covers a specific 13-month time range from 1979-02-20 to 1980-03-26.
• Includes specific chemical measurements like oxygen saturation and organic carbon.

Limitations

• Unknown sample size and spatial resolution of measurements.
• Data is over 40 years old, limiting analysis of current ocean conditions.
• Limited known parameters; other accompanying measurements are unspecified.
