TL;DR: In this paper, a combination of bubble modeling and acoustic observations of rising bubbles was used to determine what fraction of the methane transported by bubbles will reach the atmosphere, and the model was validated using methane and argon bubble dissolution measurements obtained from the literature for deep, oxic, saline water with excellent results.

TL;DR: In this article, small-scale turbulence observations allow the mixing regimes in lakes, reservoirs, and other enclosed basins to be categorized into the turbulent surface and bottom boundary layers as well as the comparably quiet interior.

TL;DR: In this article, the effects of dams on aquatic ecosystems are discussed and the consequences of altered processes may not be immediately apparent and may become obvious only after a long period of time or only in combination with other anthropogenic alterations.

TL;DR: The thermal motion of atoms and molecules is perceived on the macroscopic level as molecular diffusion as discussed by the authors, as the slow but persistent movement "down along the concentration gradient" although the average speed of the atoms is on the order of tens to hundreds of meters per second, because the molecules do not maintain the same direction long enough.

TL;DR: In this paper, a steady bubble plume model is developed to describe a weak air (or oxygen) bubble injection system used for the restoration of deep stratified lakes, where the model is designed for two modes of operation, i.e., oxygenation and artificial mixing.
