Feasibility studies and bathymetric and oceanographic surveys for the waste water treatment project. Two current meters have been placed under the sea surface at –2 m and 20m depths, these gauges have recorded current directions and speeds, salinity, temperature, conductivity for 2 months and samples have been collected under the scope of oceanographic studies. 1:1000 scale bathymetric map of the area has been produced for the same area.
