Probability Distribution of Turbulent Kinetic Energy Dissipation Rate in Ocean: Observations and Approximations

“…Three commercially manufactured microstructure profilers that are commonly employed by the oceanographic community were used during the field campaigns. In the ECS (Liu et al, ; Lozovatsky et al, ; Lozovatsky, Jinadasa, et al, ; Lozovatsky, Lee, et al, ), we operated the MSS‐60 profiler (Prandke & Stips, ) and TurboMAP (Wolk et al, ), while in BoB/SL (Jinadasa et al, ; Wijesekera et al, ) and in GS (Lozovatsky et al, ), the measurements were taken by VMP‐500 (http://rocklandscientific.com/products/profilers/vmp-500/). In shallow waters (ECS) the measurements were collected in the depth range between the sea surface and 1–3 m above the sea floor; and in deep waters (BoB/SL and GS) the profilers descended to ∼130–150 m, being limited by the length of a tethered cable and weather conditions.…”

“…Details of microstructure data employed in this study as well as the descriptions of background hydrometeorological conditions, regional circulation and local stratification are reported in Jinadasa et al (), Wijesekera et al (), and Lozovatsky et al () for deep ocean measurements taken in the BoB/SL and GS, respectively, and by Liu et al (), Lozovatsky et al (), Lozovatsky, Lee, et al (), and Lozovatsky, Jinadasa, et al () for shallow water measurements in the ECS.…”

Probability Distribution of Turbulent Kinetic Energy Dissipation Rate in Stratified Turbulence: Microstructure Measurements in the Southern California Bight

“…It carries two airfoil probes (to estimate the TKE dissipation rate ε ), fast thermistor FP7, a three‐component accelerometer (motion field), pressure (depth) sensor, and accurate temperature‐conductivity unit to retrieve information on temperature, salinity, potential density, and buoyancy frequency. The data processing followed the methodology of Roget et al () with some minor modification (e.g., Lozovatsky, Planella‐Morato, et al, —the small‐scale shear spectra was fitted to the Nasmyth () rather than to the Panchev and Kesich () canonical shear spectrum to calculate ε at consecutive vertical segments of δ ~ 1.4 m (2‐s interval with 512‐Hz sampling rate). The VMP data between the sea surface and z ~ 10 m could be contaminated by ship movement, and thus, they were excluded from data analysis.…”
