Colour-shaded seafloor relief, ice scours sites 1 to 4, Mackenzie Delta, Beaufort Sea, northern Canada, 2006-2007
Bibliographic record
Abstract
The data set is an image of colour-shaded sun-illuminated seafloor topography collected from Mackenzie Delta in the Beaufort Sea in 2007 by the Geological Survey of Canada (Atlantic) (GSCA). Data were collected with a SwathPlus Interferometric Sidescan system on Geological Survey of Canada (Atlantic), Multibeam Expedition, Beaufort Explorer 2007306. These data were collected using Differential Global Positioning System (DGPS) which determines the position of the vessel with an accuracy of 3 to 5 meters. The horizontal accuracy of the swath data is variable, depending on beam angle, water depth and inaccuracies due to sound velocity profile errors. Depth readings are accurate to within 30cm in water depths less than 30m and 1% of water depth in water depths greater than 30m. To create the colour-shaded relief a depth color gradient is applied to a grey-scale image. To have more information about this process and the other images, please refer to the Extended Metadata (XML files).
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
