This dataset is associated to the NSF OCE/Physical Oceanography funded project “Laboratory Investigation of Turbulence Generation by Surface Waves”. There are three papers in preparation that will refer to data contained within this archive. The overarching goal of this project was to address a significant knowledge gap regarding the turbulent dissipation of non-breaking surface waves. To accomplish this, a comprehensive study in the SUrge-STructure-Atmosphere-INteraction (SUSTAIN) wind-wave laboratory at the University of Miami was conducted. A combination of established measurement approaches (Particle Image Velocimetry (PIV) and Vertical Microstructure Profiler (VMP)) and new technologies (Optical Turbulence Sensor (OTS)) have been used carry out the measurements of energy and temperature dissipation under non- breaking waves. Specifically, these are the data originally collected during a series of lab experiments in SUSTAIN in Nov, 2017. All data are based on standardized lab-based observations. Over the 1-month study, TKE and temperature dissipation rate was measure in a variety of conditions, ranging from young waves (high wind speed to wave speed ratio) to old waves (low wind speed to wave speed ratio). The result showed that the short surface waves played a critical role in the generation of turbulence under the nonbreaking waves. This turbulence was modulated by the long waves. These data provide empirical evidence for the parameterization of dissipation related nonbreaking waves.
