Abstract
AbstractL'ETM (énergie thermique des mers) est une énergie marine renouvelable qui utilise la différence de température entre les eaux chaudes de surface et les eaux froides profondes. Dans le cadre d'un projet d'implantation d'une centrale ETM offshore en Martinique, une première étude d'impact environnemental a été réalisée afin d'alimenter le débat public à venir. Compte tenu de la nouveauté introduite par ce type de projet, des méthodes spécifiques ont été mises en œuvre, basées sur un travail bibliographique conséquent, associé à des mesures et des expertises très spécifiques. La méthodologie présentée ici a consisté en une première étape de recensement des données de site et bibliographiques sur les impacts de projets pouvant comporter des similitudes, afin de hiérarchiser le besoin en études complémentaires qui ont été menées par la suite : impacts acoustiques, impacts des remontées d'eau profonde, impacts du biofouling, etc. Certains de ces sujets font à présent l'objet de programmes de recherche scientifique lancés à l'issue de cette étude.The Ocean Thermal Energy Conversion (OTEC) is a marine renewable energy system that uses the temperature difference between the cold deep waters and warm surface waters to produce electricity. DCNS, a world-expert in naval defence and an innovator in energy has conducted technical, juridical and environmental feasibility studies of a plant offshore Martinique under an agreement with the Regional Council. In this context, DCNS realised a preliminary Environmental Impact Assessment in order to prepare public debate to be done further. Due to innovation of such a project, a specific methodology has been done for that. First step was to study bibliography in details, for site assessment of course, but also for impacts of other projects in the world that should present relevant similarities with OTEC (coastal thermal power plants for example). This bibliographic study dealt with thematic synthesis for each topic of physical, biological and human field that could be impacted by the project (total of 28 topics). The aim was to define priorities for specific assessments that have been done further: acoustic impacts, biogeochemical impacts of artificial upwelling, biofouling impacts, etc. Some of these topics are now on course with specific scientific research programs that have been launched at the end of this study. For each new topic, a specific methodology has been used or adapted for OTEC. These methods are made step by step, with a preliminary approach followed by a specific research program when it is necessary. Noise prediction has been done with a specific tool used for ship construction industry and a 3D propagation modelling. Biofouling has been assessed by a bibliographic approach and will be précised further with experimental moorings. Biogeochemical and biological impacts due to artificial and localised upwelling are now being studied in details with a double skill approach (physical modelling and plankton analysis), after preliminary water chemicals' analysis and modelling.Keywordsénergies marines renouvelablesimpacts environnementauxETMKeywordsmarine renewable energyenvironmental impactOTEC

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
