The environmental awareness and regulations on coastal and marine areas are constantly increasing. Both private and public sectors are now basing many decisions, developments, public audits as well as communication approaches using environmental data.

The survey of coastal and marine environment requires in particular, water analyses (physico-chemical parameters, temperature, salinity, oxygen, microbial loads, etc.), sediment assessment (particle sizes, micro-pollutants, etc.) and analyses of the live organisms (benthos, plants, magnoliophytes, seaweeds, microalgae, fishes, corals and other bio-indicators).

Mapping coastal and marine environment is crucial in the general status assessment of a specific site and the sharp localisation of the environmental concerns. This important but technical practice requires sharp methodologies: lateral sonar, mono- and multi-beam depth, aerial or satellite photography, direct surveys through dives and/or boat videocameras, Remotely Operated Vehicle – ROV, samplings, etc.); collected data are very specific and require experience and good understanding in order to sort, assess, analyses and organise for a clear reporting effort.

SEANEO provides also specific services through numerous skills and technical equipments for GIS marine studies.

SEANEO to date has been involved and works on projects related to marine environment recovering, management and protection of coastal areas (artificial reefs), Marine Protected Areas (Natural Reserves, National Marine Parks, Natura 2000 protected sites), estuaries, lagoons and various other ecosystems (coastal, marine, freshwater, tropical, etc.).

SEANEO manages also preliminary and feasibility studies, impact assessments on anthropic activities such as coastal construction works, fishing harbours and marinas, dredging, sediment extraction, sand beach nourishment, water treatment discharges, industrial and agricultural discharges, artificial reefs, renewable marine energies (off-shore windmills), underwater cable and pipe setup, etc. SEANEO also is providing scientific ecological studies (fauna, flora, species, habitats, ecophysiology, etc.) as well as socio-economic studies (fishing, sailing, diving, etc.).
