ECOS offers a wide range of services related to survey and data acquisition in the marine environment, including hydrographic and geophysical sampling, environmental sampling and underwater surveys, making use of numerous technological advances.

We have in house equipment to carry out bathymetric surveys down to 500 metres depth (Multibeam Norbit iWBM-LR) and Side Scan Sonar for geomorphological studies (C-MAX DF 100/325kHz).

We also have georeferenced underwater cameras, ROVs, 360º filming systems, which allows us to choose the best solutions to meet the requirements of each project.


Bathymetric studies are essential to have better knowledge of sea floor relief and biotopes, and therefore essential for marine projects monitoring and preparation.

ECOS has a wide experience in doing studies of underwater depth of ocean floors, using better techniques


ECOS has specialized in sampling geophysical data for offshore projects (outfall mapping, underwater pipelines, marine energy, wires or another civil engineering projects,) using innovative techniques for data collection (sub-bottom profile, side scan sonar, multi-beam, etc.)


Underwater inspections enables the information in which is based many of the studies we do.

At ECOS, we carry out underwater inspection by the use of underwater cameras and ROVs or through the direct observation of our diving team. We work across a wealth of different sectors such as water, oil and gas, renewable energy and coastal engineering.
