Marine exploration : zooming in on the springs

Each fresh water spring presents specific volumes, physical and chemical characteristics which have an impact in the sea environment. To identify these signs, Nymphea Water has developed its own set of embedded equipment and submarine detection tools.
Mainly using acoustic methods, Nymphea Water carries out marine research from an oceanographic ship with scuba divers and submarine tools to detect variations in salinity.
Three kind of techniques are being deployed : acoustic detection, three-dimensional bathymetry, salinity analysis.

Acoustic detection
Since fresh water is lighter than sea water, its ascending flow can be detected by acoustic waves beamed by sonar on a dedicated frequency.
Imaging process
- Three-dimensional Bathymetry
Using a multibeam sonar, Nymphea Water’s experts are able to make a very detailed bathymetry investigation around the submarine springs.
 - Side-scan sonar
Our side scan sonar is able to detect surface abnormalities on the sea bottom, potentially made by the spring output.
Salinity change analysis
The ship tows a salinity sensor and iso-salinity maps are plotted in the zone explored to detect any potential variations.
