Riverine Carbon Study in Alaskan Arctic Coastal Lagoons

Stefansson Sound, a coastal Alaskan lagoon system, is the focus of a three-year observational study on the influence of spring freshets. The dataset combines autonomous and direct sampling methods, applying hydrographic, optical, acoustic, and biogeochemical measurements. It is produced by the National Aeronautics and Space Administration.

Use Cases

• Analyzing seasonal carbon flux from rivers into coastal Arctic waters using biogeochemical measurements.
• Studying the physical mixing of freshwater plumes via hydrographic and acoustic data.
• Investigating water clarity and optical properties related to suspended particulates from spring freshets.
• Modeling the impact of freshwater input on coastal lagoon temperature and salinity regimes.

Strengths

• Study design spans a three-year observational period, providing seasonal and interannual context.
• Data collection employs a multi-method approach combining autonomous and direct sampling for complementary measurements.
• Dataset is associated with NASA, indicating a high standard for data collection and curation.

Limitations

• Core dataset metrics like row count, file size, and specific column names are not provided on any platform.
• License information is inconsistently reported, with one source listing 'other-license-specified' and others providing none.
• The last update date (2026-03-12) appears to be a future date, which is a conflict and suggests a metadata error.
