limnological studies (from greek limnê: lake)      >>>"home"...)

observations:

-char(s) on a spawn place :
                                    that day, on that spawn place : 1 !    25.12.08 char(s) on a spawn place (omblière)
                                                  that day, on that spawn place : 4-5 !  31.12.08 char(s) on a spawn place (omblière)

-which fish(es) shall we encounter at 4 depths at day
                                             and at 3 others at night?          which fish(es) do we encounter?)

projects of observation:

-which fish(es) shall we encounter if we descend the robot
  in a bank detected by the sounder?                                    which fish(es) do we encounter?) projects of measurements:

-measurement of the sedimentation at 4 points of the
  bottom of the Léman on 4 objects:
   -which are there since more as 120 years
   -which depths are 140m and 300m                                   sedimentation at 4 points

-measurement of the future sedimentation at different points
   of the bottom of the Léman
   -where the depths are 200m and 300m                             sedimentation

-capture for analyse of the future sedimentation at different
   points of the bottom of the Léman
   -where the depths are 200m and 300m                             sédimentation
