A diagnosis can only be run from reliable data. Consequently, our teams are equipped with regularly updated reliable resources depending on technological developments and covering a wide research spectrum.

Ecologically:

The methods drawn up allow Creocean to establish a diagnosis for how the environments operate, thereby making it possible to identify possible causes of malfunction. These methods involve measuring many variables:

• Measuring physical-chemical parameters: temperature, salinity, oxygen, Redox, nutritive salts, granulometry, turbidity, light intensity in the water column, etc. and measuring pollutants: organic enrichment, heavy metals, pesticides, detergents, etc.

- for the marine environment: skips, core drills, bottles closed by command, probes, fishing vehicles (trawling nets, hoop nets, plankton net)

- for waste: automatic samplers

• Measurement and use of bioindicators: benthic macrofauna, aquatic plants or algae, fish, etc.

• System for observing marine beds: camera (Nikon D200, D300, D800), underwater camera, towed or hung camera, ROV (Seobotix LVB150SE), Gopro…

In terms of using space:

Running many activities leads to major conflicts of interest that can only be resolved by means of approaches bringing together all the players. To do this, Creocean has developed know-how concerning:

• The inventory of usages and constraints exerted by these uses

• Identification of usage conflicts and running meetings to come to an agreement

• Writing up summary, awareness-raising and popularisation documents

In terms of fundamental and applied knowledge:

In order to systematically propose study techniques and the most advanced approaches scientifically, our teams take part or initiate Research and Technical Development programmes:

• focussed on drawing up tools to assess the quality of environments

• acting mainly on clarifying ecological indicators and methods for interpreting these indicators
