A multi-site, year-round turbulence microstructure atlas for the deep perialpine Lake Garda

A multi-site, year-round dataset comprising a total of 606 high-resolution turbulence microstructure profiles of shear and temperature gradient in the upper 100 m depth is made available for Lake Garda (Italy). Concurrent meteorological data were measured from the fieldwork boat at the location of the turbulence measurements. During the fieldwork campaign (March 2017-June 2018), four different sites were sampled on a monthly basis, following a standardized protocol in terms of time-of-day and locations of the measurements. Additional monitoring activity included a 24-h campaign and sampling at other sites. Turbulence quantities were estimated, quality-checked, and merged with water quality and meteorological data to produce a unique turbulence atlas for a lake. The dataset is open to a wide range of possible applications, including research on the variability of turbulent mixing across seasons and sites (demersal vs pelagic zones) and driven by different factors (lake-valley breezes vs buoyancy-driven convection), validation of hydrodynamic lake models, as well as technical studies on the use of shear and temperature microstructure sensors.

Automated summary

This dataset includes 606 high-resolution turbulence microstructure profiles of shear and temperature gradient in the upper 100 m depth of Lake Garda (Italy) and concurrent meteorological data. The dataset can be used for research on turbulent mixing variability, validation of hydrodynamic lake models, and technical studies on the use of shear and temperature microstructure sensors.
