Yukon River Arctic Carbon and Water Quality Measurements

NASA's Yukon Arctic Carbon Cycle Project provides field measurements from the Yukon River, delta, and plume waters. Sampling occurred during spring/summer transects in 2022 and 2023, with additional samples from similar flow regimes. The dataset includes parameters like dissolved organic matter, chlorophyll-a, radiometry, and lignin phenols relevant to Arctic biogeochemical function.

Use Cases

• Validating satellite-derived ocean color data using in situ radiometry and optical property measurements.
• Modeling carbon export and transformation in Arctic river systems using dissolved and particulate organic carbon data.
• Analyzing phytoplankton community composition via HPLC pigment measurements.
• Studying the bioavailability and chemical composition of dissolved organic matter using lignin phenol and fluorescent DOM data.
• Assessing suspended sediment loads and their optical impact through suspended particulate matter measurements.

Strengths

• Data collection spans multiple field campaigns across two years (2022 and 2023).
• Includes a wide array of biogeochemical measurements, from bulk parameters like chlorophyll-a to specific molecular tracers like lignin phenols.
• Project is conducted by NASA, indicating a connection to satellite calibration and validation efforts.

Limitations

• Specific row counts, file sizes, and complete column names are not provided by any source.
• License is listed as 'other-license-specified' on Data.gov but is 'None' on NASA Earthdata, creating a conflict.
