Coastal sensors (Trophimatique)
| Output characterisation | |
| OUTPUT SENTENCE | New miniaturised in situ sensors, capable of high frequency analysis. |
| OUTPUT TYPE | prototype |
| WATER TOPIC | Quality of natural systems |
| KEYWORDS | sensors, coastal water, water samplers |
| OUTPUT DESCRIPTION |
New designs and first uses of new sensors: Trophimatique aims at producing a multi-parameter probe, remotely operated, with a water sampler, and chemical onboard analysers (CHEMINI).
These onboard analysers can measure :
Nitrates, Silicates, Phosphates, and Ammonium.
|
| STATE OF DEVELOPMENT | The probe multisensor is developed and finished. It has been tested in situ satisfactorily, and can even be adapted to 2 buoy models (SMATCH and MOLIT) depending on the needs (surface and/or depth sampling). |
| INNOVATIVE ASPECTS AND ADVANTAGES | - New system - Everything can be remotely operated - Can sample surface water or deep water. - Can be used to validate several Water Framework Directive criteria for water characterization |
| INTELLECTUAL/INDUSTRIAL PROPERTY RIGHTS | ©Ifremer 2006 on the CHEMINI sensors used in the Trophimatique probe. ©Ifremer 2009 on the Trophimatique probe itself. |
| TRANSFERABILITY | This knowledge can be transferred to any other site with coastal waters, and could probably be used on lake or river sensors as well. |
| POTENTIAL USERS/CLIENTS | Public organisations such as local authorities to monitor their chemistry contamination levels, consultancy offices for the same purpose. |
| BUSINNESS CASE | Yes |
| Estimation of risks | |
| INNOVATIVE DISADVANTAGE | Some sensors already exist to monitor coastal waters. |
| EVALUATION OF RISKS FOR OUTPUT USERS | The risk is low : - prototypes have been tested at sea and proven to work succesfully - in some cases, storms can incur the loss of a buoy. |
| ECONOMICAL RISKS | Low risk, loss of a buoy during a storm |
| TECHNICAL RISKS | No risk, system already tested |
| MARKET RISKS | No risk, it's a new system |
| SOCIAL RISKS | No risks known |
| Steps ahead | |
| NEXT STEPS TO ACHIEVE THE STATUS 'READY TO USE' | The output is ready to use, but not well known. |
| TASKS TO BE PERFORMED |
Information about the Trophimatique sensors should be disseminated widely. |
