Iota Survey

SEABED SURVEY



In addition to bathymetric surveys, IOTA SURVEY carries out geomorphologic measurements of sea floors using acoustic imagery, magnetometry or shallow seismic records depending on the Client’s specifications, with the most suitable sensors and the best data acquisition and interpretation and mapping techniques available.


APPLICATIONS :
 Offshore oil sector: Surveys before pipe laying, debris
  survey, detection of obstructions
 Submarine cables (energy and telecommunications) :
  route survey before laying, detailed morphology of landfall
  areas, characterisation of sedimentary areas before trenching
  etc.
 
Surveys before or after works in harbour and coastal
  areas
: morphology, search for obstructions to navigation,
  evaluation of sedimentary layers, etc.


These surveys and measurements are carried out from a ship chartered by IOTA SURVEY suitable for the operation and the area in question. Positioning & navigation are carried out by GPS (DGPS, RTK), or Total Station.

EQUIPEMENT :


 Side scan sonar: EDGETECH 4100P, IMAGENEX Sportcan, Cmax 800 or others Magnetometer : Magis, Seapsy etc.
