SATURN River Station 05: Columbia River Estuary Water Quality Data 2009-2020

NCEI Accession 0162430 contains biological, chemical, and physical data collected at the SATURN River Station 05 fixed station in the Columbia River estuary. The Center for Coastal Margin Observation & Prediction collected the data, which was assembled by NANOOS and submitted to NCEI as part of the IOOS Data Stewardship Program. Data collection spans from June 2009 to December 2020.

Use Cases

• Modeling phytoplankton biomass based on chlorophyll and turbidity measurements
• Analyzing dissolved oxygen dynamics and hypoxia events in an estuary
• Studying nutrient fluxes based on nitrate concentration time series
• Correlating water temperature and conductivity with seasonal solar radiation patterns
• Tracking chromophoric dissolved organic matter (CDOM) as a tracer for freshwater inputs

Strengths

• Data collection spans over 11 years, from June 2009 to December 2020
• Measures multiple parameters including chlorophyll, nitrate, dissolved oxygen, and water temperature
• Data is collected at frequent intervals, suitable for time-series analysis
• Follows Climate and Forecast (CF) metadata convention and ACDD standards

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download
• Last updated 2020-12-23 00:00:00; freshness should be verified
• Column-level documentation is absent; field semantics must be inferred after download
