    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 bubbles, either at a constant rate in a "steady-state" model or in an initial injection where the development of a bubble "plume" is followed, is kept constant. So too are the model representations of Langmuir circulation and turbulence. An increase in temperature results in a reduction of bubble numbers, a halving at 4-m depth for a 10-degrees-C rise in temperature, while an increase in saturation level of 10% increases the bubble concentrations by factors of 3 to 4 at the same depth; the shape of the distribution curves are only slightly modified. The presence of particulates tends to increase the number of small bubbles by inhibiting dissolution.
