Abstract

fetched live from OpenAlex

Abstract Gas hydrate, a solid form of natural gas and water, is inferred to widely occur in Canadian polar and continental shelf regions and in sediment of outer continental margins. Although direct indications of hydrate are few and widely separated, conditions potentially favorable for gas hydrate formation and stability, especially low to moderate temperatures under permafrost or the deep sea, combined with favorable geological conditions for gas generation and storage, cover vast areas and indicate an immense potential for natural hydrocarbon gas in the upper 2 km of many Canadian sedimentary basins. We have analyzed the potential of gas hydrates for the vast continental shelves and Arctic permafrost regions of Canada (Mackenzie delta-Beaufort Sea and Arctic Archipelago in the north and Davis Strait, the Labrador Shelf, Scotian Shelf, and Grand Banks of Newfoundland along the Canadian Atlantic margin and Canadian Pacific margin). Our conservative calculation suggests 1010-1012 m3 of gas hydrates in these regions has an associated methane gas potential estimated to be in the range of 1012-1014 m3. The volume of methane in hydrates in Canada are geographically distributed in the following regions: 0.24-8.7 x 1013 m3 in the Mackenzie delta-Beaufort Sea, 0.19-6.2 x 1014 m3 in the Arctic Archipelago, 1.9-7.8 x 1013 m3 on the Atlantic margin, and 0.32-2.4 x 1013 m3 on the Pacific margin. The total in-situ amount of methane in hydrates of Canada is estimated to be 0.44-8.1 x 1014 m3, as compared to a conventional Canadian in-situ hydrocarbon gas potential of approximately 0.27 x 1014 m3. This comparison suggests that gas hydrates represent a possible future assurance of North American energy supply if the gas can be recovered and separated from the hydrate form.

Teacher imitation

Not 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.
