Sasaki et al. Figures: Antarctic Ocean Turbulence Micro-Temperature and Finescale Data

Microstructure and finescale parameterization data supporting figures in the paper by Yusuke Sasaki of The University of Tokyo. The dataset includes profiles of turbulence dissipation rate (epsilon), diapycnal diffusivity, buoyancy frequency, shear-strain ratios, internal wave energy, and spectral shape parameters. Data was collected from FP07 microstructure measurements in the Indian sector of the Southern Ocean across the Antarctic Circumpolar Current.

Use Cases

• Validate finescale parameterizations for estimating turbulence dissipation based on profiles of buoyancy frequency and shear.
• Analyze the relationship between internal wave polarization (CCW vs. CW shear) and turbulence generation using shear-strain ratio data.
• Study spatial variability of diapycnal mixing across the Antarctic Circumpolar Current using microstructure-derived epsilon profiles.
• Investigate the spectral characteristics of internal waves using profiles of spectral slope and Hstrain parameters.

Strengths

• Includes direct microstructure measurements of turbulence dissipation (epsilon) from FP07 sensors.
• Provides multiple derived parameter sets (finescale, spectral) enabling cross-comparison and validation.
• Data is structured to correspond directly to specific figures and table rows (e.g., eps_Fine_X for Table 1 rows a-l) in the associated paper.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale statistical analysis.
• Last update date is unknown; freshness unverified.
