The Geoforce DTS® deep-tow, sub-bottom profiler has demonstrated its operational and geological versatility in numerous global geological and geophysical scientific research studies. The unique design and capabilities of our system ensures reliability in high sea states, ease of operation, accuracy of marine subsurface imaging and optimal data resolution. 

Some of the scientific research studies for which the Geoforce DTS® has acquired subsurface data include ocean mapping and reconnaissance surveys for coring site selections. These cores are then used for carbon dating analysis.

Geoforce DTS® Project details include:

  • "Great Flood" research in the Black Sea through to the Sea of Marmara (see data above), in which the sediment transportation was analyzed by researchers from Dokuz Eylul University in Turkey and Memorial University in Canada. The survey was conducted in water depths of 100 meters in the Sea of Marmara and 700 meters in the Black Sea.

  • Tidewater glacier surveys in Yakutat Bay, Alaska where researchers from University of Northern Illinois at Dekalb and Appalachian State University studied Hubbards Glacier sediment deposits. Data were acquired in 300 meter water depths in very low sea states. ​​

  • In California, Geoforce participated in a slumping survey conducted by USGS and NRCan. In this joint project, NRCan provided the Geoforce DTS® deep-tow system and our personnel provided the technical support.

  • Geoforce deep-tow system was also deployed for gas hydrate surveys in the Gulf of Mexico for USGS.

  • Geoforce deep-tow system has been deployed for fjord mapping surveys from Puntas Arenas to Puerto Montt in Chile. Partner research institutions for this deep-water project included Northern Illinois University, NRCan Pacific, Rice University Texas and Byrd Polar Institute.


  • Multi-disciplined survey in the Ross Sea for ENEA - an Italian Government agency for Antarctica research. Data were acquired in 700 meter water depth to map the subsurface for coring sites. 

Some of the submarine fan studies for which our data has been used include:

  • '1929 earthquake' study in Newfoundland, Canada;

  • Airport runway construction collapse in Nice, France

  • Hyuemo submarine fan survey in southern California, USA

  • Corsican submarine fan survey in Corsica, France

In Canada, we have a long standing partnership with Natural Resources Canada (NRCan) Atlantic, NRCan Pacific, and NRCan Quebec to acquire high-resolution subsurface imaging throughout Canada's oceans and seaways. 

Our system has been instrumental to capturing high-resolution imaging on numerous Government sponsored subsurface mapping projects in the St. Lawrence Seaway, Newfoundland, and British Columbia, Canada; in Corsica; Nice, France; and in California, USA.  ​

In the Pacific coastal area and San Juan Islands., Geoforce partnered with NRCan and Monterey Bay Aquarium to survey possible earthquake faults. 

During the above noted NRCan research studies, the tow body's integrated boomer or sparker were deployed and source selections were made in real time to acquire data in water depths between 80 m to 4500 m in Beaufort Sea States of 4 to 5.
