The Environment is the infinite sum of all the natural conditions that can be observed in a given area. We do not measure the environment. We try to understand it.

Physical oceanography

Observation of natural mechanisms is essential for coastal engineering projects and environmental monitoring.

On the coastal zone, the construction projects require attention to the orientation and amplitude of currents, swells and tidal fluctuations. These measurements are performed using submerged current meters, ADCP (Acoustic Doppler Current Profiler) or wave measuring buoys.

These informations allow us to understand how the constructions and the surroundings will interact with each other, and thus to dimension and shape the structures, but also on the opposite to evaluate how human intervention can impact on the environment.

Deparentis can supply, install and maintain these instruments, which are generally implemented over periods ranging from a few months to several years.

Soils and water sampling

Sampling from the natural environment is of value throughout the entire life cycle of a project

Soil or water samples can be collected for many purposes, whether it is to make a punctual inventory or to set up environmental monitoring over a long period of time, to characterize the nature of the soil, for toxicological measurements or in the observation of living organisms flora, fauna, plankton.

In all cases, it is imperative for the validity of the analyses to follow rigorous procedures for the collection, handling and storage of samples. Our technicians implement good practices from the field to the laboratory to ensure the integrity of your results.

Camera drop

To survey marine biodiversity, sampling can be supplemented by live observations

For the observation of benthic species, we can deploy underwater photography, video with recording and surface monitoring (CCTV), using camera drop or ROV depending on the mission.

We collaborate with specialists in marine biology who ensure the enumeration and identification of species and more generally to conduct environmental impact studies.

Underwater noise measurement

For concerns about underwater noise or for listening to mammals, we are tuned in.

The measurement and analysis of underwater sounds makes it possible to monitor the state of the underwater environment. This study also makes it possible to detect and prevent the presence of marine mammals, for environmental impact assessments before the start of a marine works or seismic survey.
