The inter- action between the wind-driven waves and currents leads to the generation of Langmuir circulations (LC) consisting of counter rotating vortices aligned with the wind. Shortly thereafter, Langmuir turbulence (LT), that is multiple scales of LC, appear. In the field, LT length scales range from several centimeters when short capillary waves first appear up to tens of meters when the spectrum of waves broadens. We present results from a laboratory experiments where the evolution centimeter-scale LT are investigated. We present surface infrared imagery and subsurface Particle Image Velocimetry. We show that evolution from organized small scale LC to LT leads to intense surface mixing thereby disrupting the near surface molecular layers. Subsurface turbulence measurements are presented in the context of scalar (gas) flux through the air-water interface.
