Processed bathymetry data (GeoTIFF images) acquired with a ship-mounted sonar system in 2019 on the continental slope of the Canadian Beaufort Sea
Bibliographic record
Abstract
This high-resolution gridded bathymetry data set was acquired with a ship-mounted Kongsberg EM2045 Multibeam sonar system in 2019. The file is in GeoTIFF image format, is projected in UTM coordinates (Zone 8N), and was processed using the open-source MB-System multibeam sonar processing software. The grid has 4-meter horizontal resolution. The survey mission was conducted during CCGS Sir Wilfrid Laurier IOS cruise 2019-090 in the Beaufort Sea (Cruise Chief Scientist - Humfrey Melling, Department of Fisheries and Oceans Canada; project PI - Scott Youngblut, Canadian Hydrographic Service). Data were acquired as part of a collaborative research project between MBARI, the Geological Survey of Canada, and Department of Fisheries and Oceans Canada.
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.
