Columbia River Estuary Oceanographic Sensor Data from 2008 to 2021

From 2008-04-19 to 2021 05-01, this dataset contains biological, chemical, and physical measurements from a 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 NOAA's NCEI. Measurements include chlorophyll, dissolved oxygen, nitrate, salinity, water temperature, currents, and turbidity.

Use Cases

• Modeling estuarine biogeochemical cycles based on measurements of nitrate, phosphate, chlorophyll, and dissolved oxygen.
• Analyzing coastal water quality trends based on time-series data for salinity, turbidity, and temperature.
• Studying physical oceanography and current dynamics based on three-component (U, V, W) current speed measurements.
• Investigating carbon system dynamics based on partial pressure of carbon dioxide and pH data.

Strengths

• Thirteen-year temporal coverage from 2008 to 2021, providing a long-term observational record.
• Data follows standardized metadata conventions (CF and ACDD) and is provided in netCDF format.
• Includes a wide range of over 20 measured parameters covering biological, chemical, and physical oceanography.

Limitations

• Last updated 2021-05-01 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
