NOAA Miller Freeman Coastal Carbon and Ocean Acidification Measurements

Surface underway measurements from the NOAA Ship Miller Freeman cover the Bering Sea, Gulf of Alaska, and multiple U.S. West Coast National Marine Sanctuaries from May 2009 to October 2010. The dataset includes partial pressure of carbon dioxide in air and water, salinity, sea surface temperature, and barometric pressure, collected using CO2 gas analyzers and equilibrators. It is part of the Global Coastal Carbon Data Project, focusing on carbon cycle dynamics in continental margin regions.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure difference measurements.
• Monitoring ocean acidification trends in coastal ecosystems using time-series carbon dioxide data.
• Validating regional carbon cycle models with in-situ salinity and temperature observations.
• Assessing carbon dynamics across multiple protected marine sanctuaries.

Strengths

• Data spans a 17-month time range from 2009-05-16 to 2010-10-08.
• Covers a specific geographic scope including eight distinct marine regions.
• Includes data from 18 individual research cruise legs, suggesting detailed spatial coverage.

Limitations

• Column names and dataset size (rows) are not specified in any source.
• Conflicting 'last updated' metadata between platforms (2010 vs. 2026).
• License information is unavailable.
