Figure 2: Extension of the Rhöne river, the algorithm used the ratio of the 
subsurface upwelling radiance Lg, (520nm) over Lgg (550nm) on Nimbus-7 CZCS data 
June 8th 1979. 
  
In December (Fig. 3, December 28th 1978) when the Rhône outflow is not 
thm using visible, only small scale turbulences appear. They correspond to areas of low 
m) allow- (0.8mg/m3) chlorophyll content. Visualization of the turbulent features was 
obtained using the ratio L,,(443nm) over Lg (550nm) (Table II).
