NAAMES: Ship-Based Trace Gas Measurements Over the North Atlantic Ocean

Four seasonal deployments from 2015 to 2018 collected in situ trace gas data from the R/V Atlantis in the North Atlantic Ocean. The NASA NAAMES mission aimed to resolve links between ocean ecosystem processes and atmospheric aerosols and clouds. Data collection for this product is complete and resides in the NASA ASDC archive.

Use Cases

• Modeling ocean-atmosphere gas exchange based on in situ trace gas concentrations.
• Analyzing seasonal phytoplankton bloom impacts on atmospheric composition based on the four deployment phases.
• Studying marine volatile organic compound emissions and processing mentioned in the description.
• Correlating ship-based trace gas data with concurrent airborne and satellite measurements from the NAAMES campaign.

Strengths

• Data spans four distinct seasonal phases over multiple years (2015-2018).
• Part of a coordinated multi-platform NASA Earth Venture mission with ship, aircraft, and satellite data.
• Measurements provide detailed characterization of plankton stocks, rate processes, and community composition.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Most ocean data products reside in a separate SeaBass archive, not this ASDC trace gas product.
