INDEMAR Coastal Engineering specialize in the acquisition of high resolution multibeam echosounder, side scan sonar and sub-bottom profiler.



Hydrographic surveys are an integral part of INDEMAR’s services, whether as a stand-alone task or as part of a multidiscipline project.


All our data collection is supervised by a Certified Hydrographer. At our clients’ disposal is a wide array of hydrographic equipment, from single beam echosounders to dual head multibeam systems. Our hydrographic capabilities are further augmented by a full suite of state of the art positioning and motion compensation systems, and Sound Velocity and CTD units.

One of the key advantages of INDEMAR’s hydrographic services are the range of boats we have at our disposal. INDEMAR has access to the right boat for anything ranging from shallow ponds, lakes and inland rivers to estuaries, bays, harbors and open ocean.


INDEMAR can take the raw hydrographic data and provide our clients with a wealth of information through a variety of industry standard and specialized hydrographic processing packages. This includes the ability to post process dual frequency GPS into high precision Post Processed Kinematic (PPK) data which can provide high accuracy tidal corrections in areas where tide gauges are not available or cannot be easily installed. Deliverables can, among many options, include contour charts, profiles, DTM’s, 3D images and/or volume/quantity calculation.




INDEMAR specializes in conducting multidiscipline geophysical surveys nearshore. Our goal is to provide an acquisition solution which will deliver the highest possible quality data accurately, effectively and efficiently. INDEMAR’s will always come up with the best and most cost-effective logistical solution to your survey needs.


Key systems and technologies utilized by INDEMAR during geophysical data acquisition:

  • Seismic Reflection (Analogue and High Resolution Multi-Channel)
  • Seismic Refraction (Towed and Bottom Resting)
  • Side Scan/Sector Scan Sonar
  • Swath Bathymetry


INDEMAR’s geophysicists and geologists have extensive experience in planning and implementing projects, as well as interpreting and utilizing the gathered information to produce final reports tailored to the end needs of the client. This powerful combination of skills results in our ability to provide clients with one-stop shopping covering desk top studies, field measurements, analysis, and data presentation. The result is a high quality, application ready package which is both convenient and cost-effective.
