Saltwater Fingering Dataset

This dataset contains minimal Oceananigans output supporting the manuscripts “Interfacial Roughness Spectra and Finite-Depth Salt-Finger Mixing at a Two-Layer Thermohaline Interface" and "Interfacial Spectral Memory as a State Variable for Finite-Depth Salt-Finger Exchange". The deposit includes mid-plane NetCDF slice outputs and runtime TSV metadata for four nondimensional salt-fingering simulations: a mixed-spectrum baseline, a high-wavenumber endpoint case, a low-wavenumber endpoint case, and an independent mixed-spectrum seed replicate. The NetCDF files contain x-, y-, and z midplane fields saved during the simulations, including salinity, temperature, and velocity components. The TSV files contain probe time series, simulation progress records, startup timing records, and finite-value checks. The complete raw three-dimensional simulation archive exceeds 5 TB and is not included, but available from the data author upon reasonable request.
