Coastal Gulf of Alaska Biogeochemical and Climate Data

This dataset integrates remote sensing and field studies to examine the biogeochemical connections between the Copper River basin and the coastal Gulf of Alaska. It is hosted by the NASA OB_DAAC organization and was last updated in March 2026. The data focuses on fluxes of particulate iron, carbon, and nutrients, linking glacial melt to marine productivity and salmon habitat under climate change.

Use Cases

• Modeling the flux of reactive particulate iron from glacial rivers to the open ocean.
• Analyzing changes in dissolved organic carbon (DOC) and inorganic carbon (DIC) from glacier-dominated river discharge.
• Studying the impact of estuarine upwelling on nitrate flux and surface water productivity.
• Assessing climate-driven changes in river discharge seasonality and their cascading ecosystem effects.
• Investigating the creation of new salmon habitats in deglaciated watersheds recolonized by nitrogen-fixing plants.

Strengths

• Dataset is maintained by a authoritative NASA data center (OB_DAAC), indicating structured curation.
• Cross-platform presence on NASA Earthdata and Data.gov signals recognized importance and reliability.
• The description provides a detailed mechanistic model of the coastal system, from glacial weathering to fisheries.

Limitations

• Critical technical details are missing: no row counts, file sizes, or specific column names are provided.
• License information is inconsistent, listed as 'other-license-specified' on some platforms and 'None' on others.
• The dataset's temporal and spatial resolution within the described Gulf of Alaska region is unspecified.
