Dissipation rate of turbulent kinetic energy (epsilon, W kg^-1) collected over the eastern Agulhas Bank/Indian Ocean (South Africa) in March 2019

A processed dataset of turbulent kinetic energy (TKE) dissipation, epsilon, [W kg^-1] collected over the eastern Agulhas Bank/Indian Ocean (South Africa) in March 2019 is presented here. The data were collected by a Rockland Scientific MicroRider microstructure sensor (s/n MR105) that was mounted on the upper forward section of a buoyancy driven Teledyne Webb Slocum G2 shallow ocean glider (s/n 424, doi.org/10/hgwf). The ocean glider was deployed on the 14th of March 2019 in a mean water depth of 90 m at a nominal location of 26.950°E, 33.633°S, 20 km southwest of Port Alfred. Recovery took place on the 31st of March 2019 at 24.932°E, 34.923°S by RS Ellen Khuzwayo (Noyon et al., 2019). The MicroRider contained two forward facing shear probes (s/n M1071 & M1074) from which turbulent kinetic energy dissipation, epsilon, [W kg^-1] was derived (Palmer et al., 2015). The vibration of an active thruster on the ocean glider introduced low frequency noise that had a detrimental impact on shear spectra. Thus, only the derived TKE dissipation data from periods when the thruster was not operational are suitable for further analysis. Auxiliary data (latitude, longitude & thruster operation) originate from the ocean glider (s/n 424) and were derived by linear interpolation onto the sensor's time stamps. These data were collected as part of the Sustainable Oceans, Livelihoods and food Security Through Increased Capacity in Ecosystem research in the Western Indian Ocean (SOLSTICE-WIO) project (Global Challenges Research Fund under NERC grant NE/P021050/1), which aims to investigate ecosystem health and resilience in the face of climate change in the Western Indian Ocean.
