June 1992 hydrophone data from the eastern North Atlantic Ocean, collected during the ASTEX field experiment. The dataset contains spectral ambient noise measurements at 19 kHz, recorded from a buoy-deployed hydrophone near the research vessel Le Suroit. It was produced by French research groups under the SOFIA program and archived by NASA's LARC_ASDC.
Use Cases
- Analyze temporal patterns in 19 kHz spectral ambient noise to study ocean-atmosphere interaction dynamics.
- Correlate underwater acoustic data with satellite observations to validate mesoscale flux integrations.
- Investigate the relationship between hydrophone-recorded sound levels and physical processes in marine stratocumulus cloud systems.
- Use the time-series noise measurements as a proxy for studying energy fluxes of heat, humidity, and momentum at the sea surface.
Strengths
- Data originates from a coordinated, multi-instrument field experiment (ASTEX) designed for model validation.
- Provides specific spectral data at 19 kHz, offering a focused metric for analysis.
- Temporally aligned with a known intensive field observation period in June 1992.
Limitations
- Dataset size, row count, and specific parameters beyond the 19 kHz noise are unknown.
- Geographic coverage is limited to a specific region in the eastern North Atlantic during a single month.
- Data is over 30 years old, which may limit applicability to current climate conditions.
