Book Description
The oceans and atmosphere interact through various processes, including the transfer of momentum, heat, gases and particles. In this book leading international experts come together to provide a state-of-the-art account of these exchanges and their role in the Earth-system, with particular focus on gases and particles. Chapters in the book cover: i) the ocean-atmosphere exchange of short-lived trace gases; ii) mechanisms and models of interfacial exchange (including transfer velocity parameterisations); iii) ocean-atmosphere exchange of the greenhouse gases carbon dioxide, methane and nitrous oxide; iv) ocean atmosphere exchange of particles and v) current and future data collection and synthesis efforts. The scope of the book extends to the biogeochemical responses to emitted / deposited material and interactions and feedbacks in the wider Earth-system context. This work constitutes a highly detailed synthesis and reference; of interest to higher-level university students (Masters, PhD) and researchers in ocean-atmosphere interactions and related fields (Earth-system science, marine / atmospheric biogeochemistry / climate). Production of this book was supported and funded by the EU COST Action 735 and coordinated by the International SOLAS (Surface Ocean- Lower Atmosphere Study) project office.

Book Description
Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 127. The transfer of gases across the air-water interface has received much attention over the past two decades, particularly in light of increased societal interest in the exchange of greenhouse gases and pollutants between natural water bodies and the atmosphere. Gas transfer at the interface between liquids and gases holds great fascination for a wide range of researchers, from fluid dynamicists to biogeochemists. However, the phenomena of gas transfer, and the problems we face in understanding them, involve daunting issues, including multi-phase flows over a wide range of spatial and temporal scales. Such complexity is increased by the presence of surface films of both natural and anthropogenic origin, which can modify the physical and chemical nature of the interface. As a result, the challenge of working on gas transfer has stimulated the development of multidisciplinary, collaborative efforts and the development of a variety of innovative experimental and observational techniques.

Book Description
The transfer across the surface of environmental waters is of interest as an important phase in the geophysical and natural biochemical cycles of numer ous substances; indeed it governs the transition, one way or the other, be tween the dissolved state in the water and the gaseous state in the atmo sphere. Especially with increasing population and industrialization, gas transfer at water surfaces has become a critical factor in the understanding of the various pathways of wastes in the environment and of their engineering management. This interfacial mass transfer is, by its very nature, highly complex. The air and the water are usually in turbulent motion, and the interface be tween them is irregular, and disturbed by waves, sometimes accompanied by breaking, spray and bubble formation. Thus the transfer involves a wide variety of physical phenomena occurring over a wide range of scales. As a consequence, scientists and engineers from diverse disciplines and problem areas, have approached the problem, often with greatly differing analytical and experimental techniques and methodologies.

Book Description
This thesis investigates the physical mechanisms of air-water gas transfer through direct measurements of turbulence at the air-water interface. To enable this study, a new approach to the particle image velocimetry (PIV) technique is developed in order to quantify free-surface flows. PIV measurements of free-surface turbulence are performed with concurrent measurements of gas transfer in a specially constructed oscillating grid-stirred tank for a range of turbulent mixing and surface conditions. Surface turbulence, vorticity, divergence, and gas transfer are all affected by the presence of a surface film, with significant effects realized for relatively small surface pressures. Results show that while a relationship between surface turbulence and the gas-transfer velocity is an obvious improvement over that found using an estimate of the bulk flow turbulence, this relationship is dependent on the flow regime. However, the data from the grid turbulence experiments, and additional data from experiments with waves, can be reconciled by a single relationship between the gas-transfer velocity and the 1/2-power of the surface divergence, which agrees with previous conceptual models. These results demonstrate the important role of surface divergence in air-water gas exchange, and relate, in a physically meaningful way, the interactions between surface renewal, surfactants, and gas transfer.
