The Department of Navigation, Hydrography and Oceanography carries out hydrographic, oceanographic, geophysics and geological studies for state or privately owned organisations among their requests. These studies are carried out according to the revolving fund principles and bilateral agreements signed between the parties. Fees are calculated with respect to the study's nature and the rent costs determined for the material with the Naval Forces approval.
Within this context, the oceanographic and hydrographic data is collected for the following purposes:
· Coastal Engineering,
· Powerplant Constructions,
· Sewage Outlet,
· Off-shore and In-shore Aquaculture,
· Environmental Effect Evaluation Reports,
· Sea Floor Researches,
· Navigation safety,
· Shallow Water Seismic Works,
· Natural Resource Exploration,
· Bathymetry.
The data collection and analysis studies are listed as follows:
· The current data collection by either classical currentmeters or up to date ADCP’s (Acoustic Doppler Current Profiler). The data is analyzed and then a technical report and comments on the current regime are provided,
· Seismic data is collection for coastal engineering purposes to build ports, breakwaters, piers, cable and pipeline laying and surveying operations. A technical report that has comments on the continuity and thickness of layers and the faults can be provided,
· Geological interpretation of the bottom up to a depth of 30 – 40 cm,
· Side Scan Sonar applications to search for a wrecks and various objects at the bottom,
· Precise and detailed bathymetry measurements by means of single/multibeam echosounders to get the 3D images of the bottom and bottom morphology,
· Hydrographic, Topographic and Geodesic applications to visualize the shore lines,
· Measuring wave and tide data,
· Collecting and processing temperature, salinity, conductivity and density data, and measuring currents and other physical parameters of the seawater with CSTD and other instrumentation that are needed to build and operate an industrial plant in the coastal zone,
· Oceanographic, hydrographic and geophysical surveys for drilling operations,
· Magnetometer surveys to detect the magnetic deviations on the sea,
· Detecting the chemical and physical parameters of water column with CSTD’s multiple bottle water samplers or nansen bottles,
· Lithography services to print books, brochures and documents.
Data types and analysis’s, that can be utilized for engineering and scientific purposes are as follows;
· Sea water temperature, salinity, pH and oxygen measurements,
· Sea water sampling,
· Current, wave and tide measurements,
· Sea floor mapping with side scan sonar in digital and analog medium,
· Geological sampling and analysis to produce sea floor sediment dispersal maps,
· Meteorological data collecting,
· To provide archived data in accordance with accessibility and availability,
· Bathymetric data in analog, digital and vectored form.
