Influence of Bubbles on Ambient Noise in the Ocean at High Wind Speeds
Bubbles Ambient Noise High Wind Speeds
2009/1/21
Observations of ambient noise in the ocean at high wind speeds reveal significant departures in spectral shape from previously reported values at lower wind speeds. The observations were made in open ...
On the Determination of Kv in the Near-Surface Ocean from Acoustic Measurements of Bubbles
wind waves Acoustic Measurements Near-Surface Ocean
2009/1/20
When wind waves break in deep water, clouds of small bubbles are produced which are diffused downwards by turbulence. We describe here how the vertical diffusion coefficient Kv of the turbulence near ...
A Model of the Turbulent Diffusion of Bubbles below the Sea Surface
Turbulent Diffusion sea surface
2009/1/20
Bubbles produced by breaking wind waves are carried by, turbulence below the sea surface. In an earlier model of the distribution of bubble sizes with depth it was necessary to neglect certain terms i...
Air Bubbles Produced by Breaking Wind Waves：A Laboratory Study
Air Bubbles bubble clouds Wind Waves
2008/12/27
Air bubbles produced by breaking wind waves are measured in a laboratory tank to study bubble clouds produced in freshwater under various wind and wave conditions. Vertical entrainment of bubbles and ...
Some Factors Affecting the Size Distributions of Oceanic Bubbles
Oceanic Bubbles Size Distributions water temperature
2008/12/22
The effects of water temperature, dissolved gas saturation levels, and particulate concentrations on the size distribution of subsurface bubbles are investigated using numerical models. The input of b...
Bubbles in the Near-Surface Ocean：Their Various Structures
Near-Surface Ocean Various Structures
2008/12/16
Air is entrained by breaking waves to produce bubbles. A highly transient macrobubble cloud is first generated under the breaker, with larger bubbles returning sooner to the sea surface. Those remaini...
Production Functions of Film Drops by Bursting Bubbles
Production Functions Film Drops Bursting Bubbles
2008/7/25
Experimental results of Blanchard and Syzdek and of Resch and Afeti on the production of film drops by bubbles bursting at the surface of seawater were parameterized earlier by Wu. More recently, comp...
Bubbles Produced by Breaking Waves in Fresh and Salt Waters
Bubbles Produced Breaking Waves Fresh Salt Waters
2008/7/1
A greater volume of air is entrained by breaking waves to produce many more bubbles in salt, than in fresh, water. There are, however, little differences in their sizes. These results are consistent w...
The Role of Whitecap Bubbles in Air–Sea Heat and Moisture Exchange
Whitecap Bubbles Air–Sea Heat Moisture Exchange
2008/6/30
In high winds, the sea surface is no longer simply connected. Whitecap bubbles and sea spray provide additional surfaces that may enhance the transfer of any quantity normally exchanged at the air–sea...
Jet Drops Produced by Bubbles Bursting at the Surface of Seawater
Jet Drops Produced by Bubbles Bursting at the Surface of Seawater
2008/6/23
Several empirical formulas were reported to describe the production of jet drops by bubbles bursting at the surface of seawater; they were, however, based on scanty data. Recent observations of Spiel ...
Tiny Bubbles: An Overlooked Optical Constituent
Marine Marine vessels bubbles waves turbulence
2015/7/29
While it can be imagined that one of the earliest descriptions of the ocean's surface viewed by man when he put forth to the ocean on rudimentary vessels might be the intensity of whitecapping, the sc...
Methane bubbles in Lake Kinneret: Quantification and temporal and spatial heterogeneity
Methane bubbles Lake Kinneret Quantification temporal and spatial heterogeneity
2014/5/20
The amount of methane bubbles rising from the bottom of Lake Kinneret was quantified by using a dual-beam echo sounder. Both echo-counting (EC) and echo integration (EI) techniques were implemented. B...
