Oceans Monitoring

The oceans play a crucial role in climate regulation, biodiversity and the provision of natural resources. Marine geology has an essential role in understanding these processes and helping to manage the oceans for the well-being of the overall ecosystem.

      • OVERVIEW

      Glaciers are melting at an accelerated rate, which can cause an increase in earthquakes related to the release of pressure under the ice caps. Additionally, melting glaciers can increase the risk of volcanic eruptions by releasing pressure on underlying volcanoes.

      Ocean observation has become more and more sophisticated with the development of high-tech “in-situ” instruments. For example, today’s ocean observation instruments include floating buoys for real-time monitoring for estimating mammal population in critical areas and seismic monitoring of the seabed

      APPLICATIONS

      How to monitor Thwaites Glacier which is melting fast?

      The Thwaites Glacier in an isolated part of Antarctica has the potential to cause a catastrophic rise in global sea levels. It is melting fast and accounts for four percent of the world’s annual sea level rise. The scientific community would like to monitor Thwaites in order that they can determine how quickly it is warming and how threatening it could prove to be. Sercel's MATS3G acoustic modem was used on the nupiri muka, a fully autonomous underwater vehicle (AUV).

      • Underwater positioning and navigation from MATS LT

      Our light and compact underwater acoustic modem, MATS LT, was recently used by Kopadia, a French company specializing in underwater inspection projects. By allowing easy integration and delivering good results in very shallow waters, MATS LT enabled Kopadia to design, in a record time, a fully integrated positioning and tracking solution for its AUV.

      • SEISMIC DATA FROM ULTRA-DEEP UNDERWATER

      Conducting underwater seismic surveys can be an extremely challenging task, requiring the deployment of specialized equipment such as ocean-bottom seismometers in hostile environments, often several thousand meters beneath sea-level.
