• The major activity for the Marine Environment
  Unit is focused on the following
• Water quality monitoring in the gulf of Tunis,
  the gulf of Gabès and Tunisian lagoons
  (Nutriments, Heavy metals, Pesticides,
  Hydrocarbons etc)
• Assessment of actual situation and possibilities
  of development in Bizerte lake.
• Ecotoxilogy and bio supervision of the coast
• Monitoring of Phytoplankton and toxic
  contaminants in Mollusks production areas.
• Observation of the sea in connection with the

• Introduction
• In the MELMARINA Project, the fieldwork was
  undertaken in Tunisia, during February 2003, to
  verify site selections and to collect basic
  survey information pH, salinity, conductivity,
  temperature, oxygen dissolved, Chla, Suspended
  solids MES, anions (alkalinity, Cl-, SO42- ),
  total phosphorus and total nitrogen.

METHODOLOGY
Sampling
For sediment
Ekman Grab

• Surface sediment sampling was made by Ekman grab
  and heavy metals was determined.

Water
Fauna

• First,  Surface sediment sampling was made by
  Ekman grab, Cover of vegetation was assessed
  within the Grab area (14x14 cm)
• A second replicate grab sample was processed
  through a pair of metal sieves (500 and 200 um
  mesh size) and the numbers of invertebrates
  (notably, the abundance of mollusk shells) were
  estimated,

The abundance of mollusc shells were estimated
