Final report submitted to the offshore industry is based on following methodology applied during field data acquisition:
-
Field survey planning based on the survey area details obtained from clients.
-
Collection of data using duel frequency shallow-water echo- sounder and DGPS navigation system for bathymetry map generation.
-
Sub-seabed sediment sequence details are obtained using a chirp sub-bottom profiler, high resolution shallow-seismic sparker system and high resolution duel frequency side sonar, integrated with DGPS navigation data towards understanding the seabed processes. A detailed analysis and interpretation of the substrata and seabed mosaics is presented in the final report.
-
Surveys for CRZ demarcation for coastal stretches of the sea, bays, estuaries, creeks, rivers and backwaters which are influenced by tidal action are carried out using a DGPS navigation system, a high frequency echo-sounder and an optical range measuring system (LASERTRACK and 3D laser scanner) as per MoEF guidelines.
