The dataset provides backscatter strength data from a 500-kHz ADCP by Nortek deployed in Vobster Quay, a 40-m quarry in South-West England (UK). Acoustic data shows the Diel Vertical Migration of small zooplankton at dusk and sunrise on 24-28 June 2016. The dataset also contains 10 turbulence profiles acquired with a microstructure profiler (SCAMP, manufactured by PME) in the same lake during the day. The ensemble-averaged profile shows small dissipation of turbulent kinetic energy in the lake interior, where turbulence is generally suppressed by the summer temperature stratification. Note: This dataset was originally published for a draft of the paper "Can small zooplankton mix lakes?" in Limnology and Oceanography Letters (DOI: 10.1002/lol2.10047). However, the final version of the paper does not refer any more to this dataset. Access to the data is still available upon request
