Seasonal development of a turbid hydrothermal lake plume and the effects on the fish distribution

摘要

Measurements of the suspended particle concentration in a lake demonstrate the presence of a turbid hydrothermal plume. The plume, generated from a warm source develops upward carrying a suspension of particles from the bottom It is found that the vertical structure of the plume depends on the stratification of the water column, which in turn Depends on the seasonal meteorological conditions. During the stratified period of the lake, the plume is constricted to The hypolimnion zone. At the beginning of the summer season, the plume reaches the bottom of the metalimnion Meanwhile at the end of this season the plume does not.
