  • 3D Screening of master variables using the multiparameter

probes:

  • Profiling of T, pH, O2, conductivity, salinity, (chlorophyll a) at up to 22

stations in an area of typically 1 km2 in few hours

  • Outcome:
  • Efficient tracking under contrasting meterological

conditions of:

ü the spreading of an effluent

release from anthropogenic activities in coastal area

ü and its impact on the physico-

chemical conditions of the media

  • via

ü 3D visualization of conductivity

data

ü intercomparison of the master

variable profiles

  • Bioavalaible metal species measurements with the GIME-VIP

voltammetric probes

  • Profiling in selected stations which may be impacted by effluent release from natural
  • r anthropogenic sources (i.e. identified from the VIP multiprameter probe screening
  • f mater variables from a boat or the drone)
  • Outcome:
  • Efficient tracking of the input of heavy metals and change in the concentration of

their more toxic fraction :

ü Intercomparison of bioavailable metal concentrations monitored in mass water impacted

  • r not by the effluent release

  • I ntercom parison dynam ic vs total, total dissolved m etal concentrations
  • Outcom e:
  • Reliable m onitoring of the dynam ic ( i.e. bioavailable) Me fraction is required for a

m ore rigourous assessm ent of the potential ( eco) toxicity im pact of m etal released

ü Proportion of the dynamic metal species may change significantly: ü from one metal to an another (due to significant difference in metal sorption properties) ü from a given water composition to an another (i.e. metal sorption properties are function of

the physico-chemical conditions and composition of the media
