Environmental Marine Geoscience 4. Georgia Basin: Seabed Features and Marine Geohazards
Bibliographic record
Abstract
A multibeam bathymetric swath-mapping program of the Strait of Georgia has provided a 5-m resolution map of the seabed. Numerous geological features of the basin, some of which are considered geohazards, are clearly defined. During the Olympia interglacial period most of the basin was filled with sediment and then subsequently excavated during the Fraser Glaciation, except for a group of isolated banks; the southern basin was partially filled by the pro-grading Fraser River Delta during the Holocene. Marine geohazards that exist in this seismically active region include, slope stability features, active faults, gas pockmarks, and large migrating sedimentary bedforms. Other features, such as sponge reefs, have developed because of the glacial history and dynamic oceanography of the basin and provide unique and critical habitats to marine species. SUMMAIRE Un programme de leve par balayage bathymetrique a faisceaux multiples dans le detroit de Georgie a permis la production d'une carte du fond marin d'une resolution de 5 m. De nombreux elements geologiques du bassin y sont clairement definis, dont certains constituent des georisques clairement definis. Durant la periode interglaciaire d'Olympia, la plus grande partie du bassin a ete rempli de sediments, lesquels ont par la suite ete excaves durant la glaciation de Fraser, sauf un groupe de bancs isoles; la partie sud du bassin a ete partiellement remplie par progradation du delta de la riviere Fraser a l'Holocene. Les georisques marins de cette region d'activite sismique comprennent certains elements de stabilite des talus, des failles actives, des crateres d'echappement de gaz, et de grands elements topographiques sedimentaires migrants. D'autres elements, comme des recifs de spongiaires se sont developpes a cause de l'histoire glaciaire et de la dynamique oceanographique du bassin, constituent un habitat essentiel pour des especes marines.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
