Abstract
Gas hydrates are solid-like substances naturally occurring beneath the oceans and in polar regions. They contain vast, and potentially unstable, reserves of methane and other natural gases. Many believe that, if released in the environment, the methane from hydrates would be a considerable hazard to marine ecosystems, coastal populations and infrastructures, or worse, that it would dangerously contribute to global warming. On the other hand, hydrates may contain enough natural gas to provide an energy supply assurance for the 21st century. This paper attempts to separate the myths, the facts and the issues that relate to natural gas hydrates beyond the doomsday environmental scenarios and overly optimistic estimates. To cite this article: B. Beauchamp, C. R. Geoscience 336 (2004). Les hydrates de gaz, substances solides qui ressemblent à la glace, existent de façon naturelle sous les océans et dans les régions polaires. Les hydrates contiennent de grandes réserves de méthane, et autres gaz naturels, qui sont potentiellement instables. D'aucuns croient que le méthane des hydrates offrirait un risque considérable pour les écosystèmes marins, les populations côtières et les infrastructures humaines s'il était relâché dans l'environnement, ou pire encore, qu'il contribuerait dangereusement au réchauffement global. Par contre, les hydrates pourraient contenir assez de gaz naturel pour constituer une source énergétique fiable au XXIème siècle. Cet article s'efforce de séparer, au-delà des scénarios environnementaux alarmistes et des évaluations trop optimistes du volume des ressources énergétiques, les mythes, la réalité et les enjeux gravitant autour des hydrates de gaz naturels.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
