FIRE ASTEX: Underwater Hydrophone Sound Data from the Atlantic Ocean, June 1992

Hydrophone data measuring underwater sound at 19 kHz, collected during the Atlantic Stratocumulus Transition Experiment in June 1992. The dataset was created by the National Aeronautics and Space Administration as part of the First ISCCP Regional Experiments to study cloud systems and energy transfer between the ocean and atmosphere. It includes files in BIN, TAR, ISO, HTML, and PDF formats.

Use Cases

• Analyze spectral ambient noise at 19 kHz to study underwater acoustic environments.
• Investigate energy and momentum flux transfers between the sea surface and atmospheric boundary layer.
• Validate satellite integrations of heat and humidity fluxes in the presence of mesoscale structures.
• Study the physical processes determining the life cycles of marine stratocumulus cloud systems.

Strengths

• Data originates from a coordinated, multi-instrument field experiment (FIRE ASTEX) designed for model validation.
• Collection was part of a nested measurement strategy to quantify fluxes at different scales, from local to mesoscale (50 km).
• Dataset is associated with a specific research vessel (Le Suroit) and time period (June 1992).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to the specific June 1992 Atlantic Ocean campaign.
