Abstract: A detailed understanding of the properties of liquid turbulence below theair-water interface of environmental water bodies is the key toward the correctparameterization of interfacial transfer processes for mass,heat and momentum.Inparticular,the transfer of gases across the interface is a critical element in thenatural geochemical cycling of materials as well as for the transport andtransformation of man-made pollutants in the environment. Problem areas forenvironmental engineers range from such traditional concerns as oxygen transfer(tocompensate for biochemical oxygen consumption)to reactive gases such as ammonia orcarbon dioxide(important for the "greenhouse effect")to toxic organic chemicals.
